    Descriptive info: UV Lamps.. UV Display Lamps.. Caution: As with any mid-wave or short-wave ultraviolet source, you must not allow anyone to look into the light or shine it on bare skin as it will cause damage to the eyes and/or sunburn to any exposed skin.. Although we take our big lamps in the field, the display lamps are primarily intended for inside conditions.. These high-powered ultraviolet display units will light up your fluorescent collection for an awesome exhibit.. The units are available in long-wave, mid-wave, and short-wave ultraviolet models as well as combinations of the various wavelengths.. We currently make models from 9 watts to 190 watts.. The bigger units operate on 110 volt AC, 60 Hertz power, but I can custom make them to operate on 230 volt AC, 50 Hertz as well.. For 230 volt AC, please allow a few weeks extra for manufacturing because I do not keep all of the necessary parts here in stock.. The standard display units are made in a metal fixture with a black powder coat finish, stainless steel lids and a black plastic handle.. The metal boxes come in 4 basic sizes - small 3" x3" x15" (7.. 62cm x7.. 62cm x38.. 1cm), medium 4" x4" x18" (10.. 16cm x10.. 16cm x45.. 72cm), large 4" x8" x18" (10.. 16cm x20.. 32cm x45.. 72cm), and extra-large 4" x5" x24" (10.. 16cm x12.. 7cm x60.. 96cm).. As special orders, I can make the display units out of oak or Baltic Birch plywood.. When working with the wooden boxes, I can resize many of the dimensions to fit your needs.. I currently offer the smaller units in 12 volt DC versions or 110 volt AC versions.. The enclosures for my line of 9 watt lamps are black ABS project boxes.. They come in two sizes 2.. 5" x4" x7.. 5" (6.. 35cm x 10.. 16cm x19.. 05cm) and 3" x6"x8" (7.. 62cm x 15.. 74cm x20.. 32cm).. Models of Lamps.. 36 watt units and 60 watt units.. Single bulb units.. I no longer make a 25 watt unit.. The size of the box and the filter are the same for 25 watt bulbs, 36 watt bulbs and 60 watt bulbs.. Since the 36 watt bulbs are so much stronger than the 25 watt ones, it does not make sense to me to make a 25 watt unit.. These units all use the 4"x4"x18" box.. The standard unit is set up for 110 volt AC, 60 Hertz power, but I can make these units with 230 volt AC, 50 hertz power.. Dual bulb units.. These units are available in the 4x4x24" box and all of the units have an installed fan to keep the box cool.. They can be any combination of the following bulbs: 36 watt SW, 36 watt MW, 36 watt LW or 60 watt SW.. The MW and SW bulbs require Hoya glass to pass the UV.. 95 watt and 190 watt SW Units.. 95 Watt Model.. These Units are also available in the 4"x4"x24" box.. For the 95 watt unit, the Hoya filter glass size is 3"x19 5/8".. 190 Watt Model.. The 190 watt unit has two of the 95 watt bulbs and the filterglass is 4"x19 5/8".. Philips rates the bulb at 32 watts of UVC at 100 hours of use.. For comparison, a Philips 25 watt SW bulb emits 7 watts of UV C.. These units require a fan to cool the bulb.. 190 watt SW units.. Ballasts.. A few years ago, I switched over to hi-efficiency, electronic ballasts for all of my larger AC lamps.. The electronic ballasts cost quite a bit more than the magnetic ballasts, but they give off more light and they do not wear out the bulbs as fast as the magnetic ballasts.. The smaller 9 watt (see description below) AC units do still use magnetic ballasts.. Futher, in both the AC and DC versions, I am using 13 watt ballasts  ...   it were a 13 watt bulb.. This does shorten the life of the bulb a little, but the original rating is for 10,000 hours of use.. I felt that the increase in UV output was worth the slightly shorter life of the bulb.. This only applies to the DC models.. *** Special Bulbs ***.. One very strong selling point for the Philips bulbs that I use, is that they put out more UV over the life of the bulb than the standard quartz bulbs and they also have much less mercury in them.. Philips also uses a different kind of glass so that none of the ozone producing UV gets emitted from the bulb.. Most of the standard quartz bulbs do produce ozone.. Philips figured out that part of the reason that the standard quartz bulbs lose efficiency is that the mercury gets into the structure of the quartz and changes it so that less UV gets through.. Because the mercury absorbs into the glass, the standard quartz bulbs have to put in about 5 times as much mercury, so that there will be enough mercury left at the end of the useful life of the bulb.. Philips found that putting a coating of yittrium oxide on the inside of the bulb helps to stop the mercury from getting into the glass.. This coating allows the bulb to emit much more UV over the life of the bulb.. Tests have shown that at 10,000 hours, the quartz bulbs are emitting only about 53% of the UV that they did when the bulbs were new.. The Philips bulbs, on the other hand still emit about 80% of the UV that they started out with.. The quartz bulbs do start out with a little more at the beginning since the quartz glass allows about 92% of the UV through, while the boro-silicate glass only allows about 88% of the UV through.. The cross over point where the Philips bulb starts outperforming the quartz bulbs is about 2,000 hours, so for the rest of the 8,000 hours of typical use, the Philips bulb produces much more UV than the quartz bulbs.. Standard lamps include 9 watt, 18 watt, 35 watt, 36 watt, 60 watt, 60 watt rotating, and 95 watt models.. The 9 watt can be AC or DC, while the 18 watt and 35 watt are DC only.. All larger lamps are AC.. Special order lamps include larger models with multiple bulbs.. Allow 6 weeks for manufacturing and delivery.. The.. attached file.. shows retail prices and a breakdown of standard versus special order lamps.. UL Listing.. None of my lamps are UL listed at this time because that process is very expensive and out of my price range to make happen.. The UL Listing costs about $6,000 for each model of lamp.. However, there is another way to meet the requirement.. The UL Listing only applies to the part that plugs into the 110 volt AC.. If a UL Listed 12 volt power supply provides the power for the big display lamp, the whole unit meets the UL requirement.. I am told that the Fire Marshals at the big shows are requiring display lamps to be UL Listed.. These DC units should satisfy the Fire Marshal as long as the power supply is UL Listed.. I am in the process of making some 36 watt display units (and probably the 60 watt unit also) in 12 volt DC versions.. The 12 volt versions are a little more expensive because of the inverter ballasts and also because of the power supply.. In addition to making my line of DC display lamps, I am looking into the possibility of offering to convert other types of lamps to DC.. If you think you would like to convert some of your lamps to DC, please e-mail me to discuss it.. I won't offer the service if there is no interest in it..

    Descriptive info: Frequently Asked Questions.. What are fluorescent minerals?.. The term "fluorescent" generally means that the material absorbs ultraviolet radiation and re-emits the energy at a different energy level.. Fluorescent minerals look like ordinary rocks, except when you expose them to ultraviolet light! Then, they fluoresce with fantastic colors.. Where do I get fluorescent minerals?.. Fluorescent minerals occur nearly everywhere in the world.. I mine fluorescent minerals near Wickenburg, AZ.. I sell the minerals that I mine and I also sell fluorescent minerals from other localities.. The north-west corner of New Jersey is world famous for fluorescent calcite (red) with willemite (green).. Greenland is also relatively famous for fluorescent minerals with a large variety of very bright colors.. See also the links for other sources of fluorescent minerals.. What do the different colors mean?.. There is no deep meaning to the colors.. Most of the time, the fluorescent color is because of trace amounts of some other element mixed in with the basic rock or mineral.. For example, trace amounts of uranium (a few parts per million), in silicates such as quartz, agate, petrified wood, common opal, and chalcedony, will cause the material to fluoresce with a strong yellow-green color.. Many uranium ores also fluoresce the same bright yellow-green color.. Similarly, calcite can fluoresce many colors depending on the trace amounts of other elements.. Calcite commonly will fluoresce a shade of red ranging from a dull red to a fiery-red, due to manganese and a small amount of lead.. If the manganese has replaced between 3% and 15% of the calcium, the calcite will fluoresce red with the very brightest color occurring around 5.. 5% manganese.. Calcite with trace elements other than manganese can fluoresce green, light blue, bright blue-white, yellow and/or hot pink.. Why are they called fluorescent lamps?.. They are called fluorescent lamps because the white powder (a blend of phosphors) actually fluoresces in response to the ultraviolet radiation on the inside of the tube.. Wikipedia, the free encyclopedia, has an excellent discussion of fluorescent lamps including the history and all technical aspects.. Fluorescent lamps on Wikipedia.. How does a fluorescent lamp work and what is a ballast?.. Here are some links to some very complete discussions of all aspects of fluorescent lamps and ballasts.. The pages even discuss and show wiring diagrams:.. http://members.. misty.. com/don/f-lamp.. html.. http://www.. uvlamp.. com/TechArt/uvlamp.. htm.. http://home.. howstuffworks.. com/question337.. What are Ultraviolet (UV) lamps?.. These are special fluorescent tubes/lamps/bulbs that emit ultraviolet radiation also see above and below.. The low pressure mercury vapor tubes that emit UV C radiation do not have any phosphor in the tube the mercury vapor produces the UV C radiation.. For low, medium, and high pressure mercury vapor tubes that emit UV B, UV A, or a blend of UV A and UV B, the inside of the tube is coated with a phosphor or a blend of phosphors.. Ultraviolet phosphors are materials that absorbs the UV C and re-emit the energy as UV A or UV B radiation.. What makes your Way Too Cool lamps special?.. I manufacture a full line of ultraviolet lamp fixtures ranging from 9 watt models to 190 watt models in many combinations of UV A, UV B, and UV C.. These lamp fixtures are available in 12 volt DC versions and AC versions that will operate on 110 volts or 230 volts AC and 50 or 60 hertz.. What is ultraviolet radiation (UV)?.. The electromagnetic spectrum ranges from cosmic rays at one end, to radio waves at the other end.. The ultraviolet (UV) region of the electromagnetic spectrum is situated between visible light and x-rays, with the wavelengths of the UV A radiation being shorter and more energetic than violet visible light and the wavelengths of vacuum UV radiation being slightly longer and less energetic than x-rays.. The full UV radiation spectrum ranges from wavelengths of about 100 nanometers (nm) to 400 nanometers and the UV radiation spectrum is usually divided into 4 sections; vacuum UV radiation (also called far or very UV, from 100 nm to about 200 nm), UV C radiation (also called germicide or short-wave UV, from 200 to about 280 nm), UV B radiation (also called mid-wave or medium-wave UV, from 280 nm to about 320 nm), and UV A radiation (also called poster lamp , black-light, or long-wave UV, from 320 nm to 400 nm).. Some sources (such as the US FDA), define the range of UB V as being from 260 nm to 320 nm, and other sources give the upper range only as high as 315 nm.. In the figure below, the disputed region of the UV B (midwave) is in a shaded color.. Where does UV radiation come from and what is it used for?.. In addition to sunlight, UV radiation can be emitted from a variety of sources such as light emitting diodes (LED s), lasers, electric arcs (especially as in arc welding), xenon bulbs, halogen bulbs, excimer bulbs, and mercury vapor lamps/tubes of low, medium and high pressures.. UV C radiation is used extensively for sterilization, purifying, and deodorizing applications in food, air, water, and general surface sterilization processes because the UV C radiation not only deactivates micro-organisms such as: bacteria, molds, spores, fungi, and viruses (by direct irradiation which damages the DNA such that the micro-organisms cannot reproduce), but the UV C radiation also breaks down the chemical bonds of alcohols, pesticides, chloramines, and other contaminants such as NDMA or MTBE.. UV B radiation is the agent that causes human skin to sun-burn and the UV B radiation is needed to start the suntanning process.. The lamps/tubes used in suntanning booths usually emit a combination of UV B and UV A.. UV B is also used extensively in various medical treatments especially for skin diseases.. UV A radiation is used for special effect lighting, suntanning, photo-lithotropy, and photo-chemistry.. Are Ultraviolet lamps dangerous?.. Yes, there are several SAFETY CONCERNS about UV lamp fixtures to be considered.. If using the lamp by hand, you must make sure that it is NEVER pointed toward someone, so as to prevent "sunburn" to anyone's eyes or skin.. Also make sure that the UV is never directed towards any animal's eyes.. It is always a good practice to wear UV blocking safety glasses when looking at, or when collecting fluorescent minerals.. Almost all of the inexpensive plastic safety glasses will block the SW UV.. You can check to see that your glasses do block the UV, by putting the glasses close to a fluorescent rock and pointing the UV lamp toward the rock.. The portion of the rock directly below the glasses will remain dark while the rest of the rock fluoresces.. It is also a good idea to wear long sleeves, long pants, and to put sun-block on any skin that may be exposed to the UV.. For use in display cases, the SW and the MW UV has to be contained within the display case to prevent sunburns.. I use UV blocking Plexiglass or UV blocking Lexan to make the "window" to be able to look in the display case while at the same time protecting people from the UV.. Here are some links to information about UV and eye damage:.. http://radsafe.. berkeley.. edu/nir1101b.. tsbvi.. edu/Outreach/seehear/fall99/ultraviolet.. who.. int/uv/faq/uvhealtfac/en/index.. blackwell-synergy.. com/doi/abs/10.. 1111/j.. 1751-1097.. 1989.. tb05553.. x.. How does UV radiation create a sun tan?.. (Excerpted from.. US Patent 4967090.. ) Skin pigmentation and thickening of the upper layer of the skin called the corneum are the body's natural protective reactions to exposure to.. ultraviolet energy produced by the sun; these reactions are the skin's defense against further assault.. Skin pigmentation, or tanning, is the result of a complex biological process, and to understand it, one most understand the skin's response to different wavelengths of ultraviolet radiation.. Deep down in the skin are special cells called melanocytes.. Once these are stimulated with ultraviolet light, they will utilize substances which they have stored up to produce the pigment melanin.. Because these substances only absorb.. (UV B) ultraviolet light, these UV B rays must be present in order to achieve melanin production.. Longer wavelength ultraviolet (UV A) can also formulate melanin but only when there exists enough sensitizing material in the skin to bring about a UV B-type reaction.. However, this requires a very high radiation UV A intensity for a long period of time.. On the other hand, UV B can induce the same desired melanin production utilizing very low levels of radiation with more frequent exposures.. The pale pink colored melanin granules formed in the melanocytes will travel upward toward the horny layer or corneum.. They are stored around the nuclei of the keratin cells there.. In this manner, the pigment protects the UV B sensitive DNA located inside the nuclei without impeding the other positive effects of ultraviolet light.. In the preliminary stages of melanin production, very little protection is offered to the skin.. In order to render the pigmentation process effective, the melanin granules must darken (oxidize).. This requires a higher dosage of longer wave UV A.. The dosage of UV A must be sufficiently high in order to provide enough energy to initiate the oxidation process.. It must be remembered that UV A rays are not as energetic as UV B rays.. Long-wave radiation is essential because high doses of short[er]-wave rays will activate substances in the body such as absorbic acid and cysteine which hinder the tanning process.. These antioxidants not only inhibit oxidation of pigment but can even reverse the process.. Thus, UV B serves to synthesize the pigment granules while UV A ensure their oxidation.. Together they form a light protection mechanism.. UV B is also essential in developing the skin callosity in the horny layer or corneum.. This light-induced thickening stabilizes the skin to guarantee protection from excessive radiation.. After the skin has been exposed several times, this callosity will develop within one to three weeks and can remain for several months.. Most tanning lamps produce a spectrum of ultraviolet light which is similar to that of the sun.. Most lamps provide the small amount of UV B necessary to initiate the tanning process while at the same time, providing the UVA needed to darken the pigment (melanin).. Ultraviolet tanning lamps and tanning equipment used in the United States must comply with very specific regulations which are enforced by an agency of the Food and Drug Administration.. These regulations restrict certain ultraviolet lamp characteristics and require extensive labeling of lamps and suntan equipment.. The U.. S.. FDA defines UV A as the region of 320 nanometers (nm)-400 nm and UVB as the region of 260 nm -320 nm.. In the design of sun-tanning equipment and UV sources it is necessary to consider that tanning ability and tanning characteristics vary from one individual to another.. In this regard there are two main factors which should be considered: 1.. Skin Type this refers to the (genetic) capability of an individual to produce and maintain a pigmentation in the skin.. It is determined by the histologic response of the skin to ultraviolet radiation and classified by the observable effects.. 2.. Present Skin Pigmentation - this refers to the relative pigmentation level of the skin at the time just prior to UV exposure.. Previously well-tanned skin, exhibiting a high level of pigmentation is generally more resistant to erythema (sunburn) and hence may tolerate higher levels of UV B before the onset of Minimum Perceptible Erythema (MPE).. Increased UV B will elicit, however, an increased melonogenic effect ultimately leading to a darker appearing skin.. Previously, un-tanned skin will be more susceptible to UV B induced erythema and therefore UV B levels should be minimized in the early portion of an indoor tanning program.. Because of the factors mentioned above it is necessary in a commercial indoor tanning application or in the consumer tanning products marketplace to offer sunlamp products which are appropriate to the range of "tannable" skin types and skin conditions.. This means that sunlamp product manufacturers, to be fully competitive, must offer products which produce the radiative characteristics necessary for safe and effective tanning of a range of skin types and conditions.. To this end many manufacturers offer a variety of ultraviolet sources which when used in conjunction with their tanning equipment give the desired ranges of UV A and UV B appropriate for the person(s) undergoing the tanning process.. To cover the range of ultraviolet lamps to meet the needs of the market, equipment manufacturers and distributors generally make available three separate groups of lamps having the following characteristics:.. 1.. Lamps with a relatively low proportion of UV B radiation approximately 1% UV B/UV A and lower,.. Lamps with an intermediate proportion of UV B; approximately 1.. 0-3.. 0% UV B/UV A, and.. 3.. Lamps with a relatively high proportion of UV B; 3% and above, usually to 5% maximum.. In all cases, UV A is defined [by the US FDA] as the region of 320 nm -400 nm, [and ] UV B is defined as the region of 260 nm-320 nm.. How does a sun-tanning lamp differ from one used to make rocks and minerals fluoresce?.. The tubes/lamps/bulbs used for rock collecting usually have a relatively narrow band of UV emission and they do not generally use blends of phosphors as the sun tanning lamps do.. The fluorescent response of many minerals can be very specific to the wavelength.. For example, some calcite from Mexico fluoresces three different colors depending on the wavelength to which it is exposed.. This calcite fluoresces a bright blue-white under UV C radiation with a peak of 254 nm, yellow under some UV B tubes/lamps with a peak around 315 nm, yellow under UV A with a peak of 352 nm, and hot pink under UV A with a peak of 368 nm.. If such a specimen of calcite is exposed to a sun-tanning lamp, the fluorescent response would probably be mixed such that the pink and the yellow would blend into a salmon color.. A relatively small number of other minerals also exhibit a different response to various UV wavelengths, so mineral collectors prefer UV tubes/lamps with relatively narrow emission bands.. How does UV C disable micro-organisms?.. More than 100 years ago, scientists realized that some components of strong sunlight were capable of disinfecting and sterilizing items by killing micro-organisms (such as bacteria, spores, molds and viruses).. One such portion of the electromagnetic spectrum was identified as being ultraviolet radiation of wavelengths between 200 nanometers (nm) and 300 nanometers.. The region of ultraviolet radiation is often called UV C, short-wave UV, or germicidal UV.. The DNA in most life forms is double stranded with hydrogen bonds connecting parts between the two strands.. When micro-organisms are exposed to UV C radiation, the energy is absorbed in the hydrogen bonds in the DNA, causing some of the bonds to rupture and also causing portions of the DNA to fuse.. This disruption of the DNA chain prevents the cell from replicating and the micro-organism ceases  ...   DC fixtures, no additional power supply is needed because the 12 volt power supply will operate both the fan and the bulb(s).. For the AC versions, I install an internal 12 volt power supply to run the fan.. In the larger lamp fixtures, am currently using a 12 volt power supply that runs on any power from 100 volts to 240 volts and from 47 to 63 hertz.. In the smaller units, I still use 110 volt AC 12 volt power supplies.. Lyman Hays, an electrical engineer, did independent testing of various lamp fixtures and reported his findings in the UV Waves (the newsletter of the Fluorescent Mineral Society (FMS).. uvminerals.. org.. Of particular interest is Lyman s statement: "In my earlier discussion, I observed the Way Too Cool 95 Watt light is the brightest of those tested.. According to Figure 2, its peak irradiance is about 11% higher than that of the next brightest light, the TripleBright II.. Measurements for Figure 2 were made after the lights were on long enough for their internal air temperatures to stabilize.. If instead comparison is made using the highest irradiance values reached as the lights warmed, then the Way Too Cool 95 W reached peak irradiance 43% higher than did the TripleBright II.. This example serves to illustrate the importance of temperature control.. ".. As a direct result of Lyman's testing, I have added much more cooling to the 95 watt lamps (and to many of the other display units).. On the larger wattage units, I now use TWO centrifugal blowers rated at about 40 CFM each - with one blower pulling air into the unit and one blower pushing air out of the unit.. This provides much more cooling air flow and as a result, the UV output is greatly increased.. Using two fans does not double the air flow, but it does increase it by up to 50%.. The 60 watt bulbs/tubes require a pretty strong cooling air flow as they were designed to be in HVAC ducts with air flow past them.. The only time I would not run the fan is if I were outside running the lamp under cold conditions.. DO NOT LOOK AT THE OUTPUT of the lamp unless you have some sort of eye protection - even cheap plastic safety glasses allow you to actually look right at the filter.. How can you tell if the bulb is too hot or too cold?.. DO NOT LOOK AT THE BULB UNLESS YOU HAVE UV BLOCKING GLASSES ON.. The SW filter glass always looks redder than LW glass because the Hoya glass does allow a little red light to come through.. However,.. when the bulb is either too cold or too hot, the filter glass and the bulb will appear redder than when it is at a good temperature.. When you first turn the lamp on, it will take a few minutes for the temperature to stabilize.. As it warms up, the color will shift a little.. Normally, the SW filter will look a nice purple and the LW filter will look a nice blue.. If the bulbs are too hot OR too cold, the UV output changes and the color shifts so that the SW bulb looks much more reddish.. I was out collecting one time when it got down to nearly freezing and the lamp did not have a switch to turn the fan off, so it looked really reddish and the UV was way down.. Do both the 9 watt AC 110V and DC 12V lamps run in overdrive (i.. e.. 13 watt ballast) or is it just the DC unit?.. Both the AC and the DC versions are overdriven with 13 watt ballasts.. The 9 watt units use an "instant start ballast", which is the roughest on the bulbs for turning them on and off because they get the full power right away and each time a little of the coating on the filament gets burned off.. I overdrive all of the 9 watt bulbs with 13 watt ballasts because it produces almost 50% more UV.. With a standard 9 watt ballast, Philips rates their 9 watt bulbs for a lifetime of about 3,300 on/off cycles.. The 13 watt ballasts are slightly harder on the filament, so we estimate about 3,000 on/off cycles.. I have contracted with a company to test the life cycle of several of the lamps/tubes.. I do have a few of the 13 watt ballasts that will operate on 240 volts 50 hertz.. The 240 volt ballasts are not a stock item here in the USA, however, one of the major manufacturers does custom make them at three times the cost of the 115 volt versions.. The 230 volt, 9 watt ballasts are bigger than the 110 volt versions and I cannot fit three of them into the enclosure, so I cannot make a three wavelength model that will plug directly into 230.. For these reasons, I recommend using the DC models with a universal 12 volt power supply in countries that have 230 volt AC power.. As it stands now, I am limited to instant start ballasts on the 9 watt bulbs because the available lamps/tubes only have two connections exposed i.. two pin bulbs.. I am working on getting bulbs with 4 pins instead of 2 pins.. That would allow me to use a more friendly ballast and to extend the life well beyond the 3,000 on/off cycles.. So far, I have not found the bulbs in that style, but I am looking.. Because the big display lamps are commonly placed inside or on top of a display case, I can put the switches on the power cord, for a slight extra fee.. I use a small project box to hold the switches and I run a cord with multiple pairs of wires between the switch box and the lamp.. Also, for all of the bigger bulbs/tubes, the ballasts I use are programmed start ballasts - when first powered up, the ballast sends a small amount of power to warm up the filament, then it increases the voltage until the bulbs "fires", then it ramps up the power until the lamp is at full power.. The whole process takes 1 to 2 seconds, but it means you can turn the bulbs on and off up to 50,000 cycles before burning out the filaments.. For the bigger lamp fixtures, the ballasts I am using are called "programmed ballasts".. Whenever power is applied, the ballast sends a specific amount of power to warm up the filament of the bulb/tube, then the ballast starts raising the voltage until the bulb/tube lights up (when the voltage drops due to the ionization of the gas), and then the ballast raises the current until the bulb/tube is at full power.. The entire process takes a second or two every time the bulb is turned on.. I spoke with the Electrical Engineer who designed the ballast and he said it was designed to be able to cycle a Philips bulb on and off for at least 50,000 cycles without burning up the filament.. If you will be cycling the bulb on and off, this becomes important to you.. Why do we need filter glass?.. All of the easily available UV sources emit white light along with the UV.. This white light interferes with looking at the fluorescent colors and it makes the colors look washed out or faded.. The filter glass blocks the white light while letting the majority of the UV pass through the filter.. The best SW filter glass available is made by Hoya of Japan.. However, transmitting SW UV is not easy.. Hoya glass will only transmit about 64% of the SW UV when the glass is new.. As the glass is exposed to long term UV C, the UV C transmission decreases until the filter eventually needs to be replaced.. The LW glass on the other hand passes about 85% of the LW UV and never needs replacing.. Can the long wave tube be substituted for a medium wave tube at a later time? Are the lamps tuned to work with only a SW/LW combination?.. The SW bulb has Hoya SW filter glass.. The LW bulb has the much less expensive LW filter glass.. The LW filter glass will only pass about 60% of the MW, while the SW glass will pass about 90%.. You could switch the SW bulb with a MW bulb, but I do not think you would be happy with the MW bulb behind the LW glass.. However, I can make the lamps with any combination of parts.. The SW glass WILL work with the either the LW OR the MW bulb, so it is possible to use TWO pieces of SW glass in building a lamp fixture, but it adds to the cost because of the difference in the cost of the SW glass vs.. the LW glass.. How big a display case will a lamp fixture light up?.. Obviously, in the world of fluorescent minerals, more UV power is better.. If the very powerful lamps are out of your price range, you will want to use a smaller case.. The 9 watt units will work with a small display case up to a 1 foot cube or so but you will want a unit with a fan if the lamp fixture will be on for long periods of time.. The 9 watt units are OK at about 1/4 to 1/3 of a meter high with a spread of about 1/3 of a meter.. A 36 watt SW (UV C) lamp fixture will light a standard case that is 2' tall x 2' deep x 4' wide, BUT the minerals at both end of the case will not be lit well so you would need specimens that fluoresce brightly at the ends.. According to Philps a 36 watt tube/bulb emits 12 watts of UV C.. A 60 watt SW lamp fixture will light a standard (2'x2'x4') case fairly well and will reach out to the ends, but it will not be bright if you raise the lamp much higher than a standard 2' tall case.. A 60 watt bulb emits 18 watts of UV C.. A 95 watt SW will do a good job in a 5 foot tall case if the specimens at the bottom fluoresce well.. A 95 watt bulb emits 32 watts of UV C.. I also make a unit with a 95 watt SW and a 65 watt (or a 60 watt) LW bulb.. A 120 watt SW unit has two 60 watt bulbs so it emits 36 watts of UV a bit more than a 95 watt unit.. A 190 watt SW unit has two 95 watt bulbs so it emits 64 watts of UV C.. The Franklin Mineral Museum in New Jersey recently revamped their 28' long display with 8 of the 190 watt SW units.. As for dual units, to my eye, a unit with 36 watt SW and 36 watt LW always seemed a little miss-matched on response in a group of mixed SW and LW fluorescent minerals.. The LW minerals seem brighter to me than the SW minerals - yes, the LW minerals.. To my eye, the 60 watt SW/ 36 watt LW combination gives a very good blend of SW and LW.. I think the answer lies with the filter glass.. Hoya glass will transmit about 64% of the SW UV when the glass is new.. As the Hoya glass is exposed to UV C radiation for long periods of time, the UV transmission decreases until it eventually needs to be replaced.. The LW glass on the other hand passes about 85% of the LW UV and never wears out.. Now let s look at some realistic numbers.. According to Philips, a 36 watt LW tube emits a total of 9 watts of UV A and a 36 watt SW tube emits a total of 12 watts of UV C.. Not all of the total UV energy will be directed out through the filter glass, but we can use the numbers that Philips provides for a relative comparison value because the two lamp fixtures are of the same design.. If you crunch the numbers, 64% of 12 watts (for the UV C tube and filter combination) is almost exactly the same as 80% of 9 watts (for the UV A tube and filter combination).. They both end up with about 7 watts of UV available.. Battery Power.. The 9 watt models (with the 13 watt ballasts) use about 1 amp for each bulb that is turned on.. The common lead acid battery packs are usually 7 or 8 amp-hours.. For a triple unit with all three 9 watt bulbs on, an 8 amp-hour battery will last for approximately 2.. 5 hours of use and there is not any quick and easy way to recharge the smaller batteries while out in the field.. Harbor Freight Tools.. www.. harborfreight.. sells a "jump start battery" system with a 17 amp hour battery, a built in charge, white light, and a volt meter.. The normal price is $59 and it goes on sale regularly for $39.. There is also a 12 amp-hour unit.. 12 VOLT JUMP START AND POWER SUPPLY.. JUMP-STARTER AND 12 VOLT POWER SUPPLY.. For a useful comparison, I had a 36 watt SW unit in the field all night using the 17 amp-hour battery unit.. I ran the unit from about 5 PM to about 1 AM, then again from 2 AM to about 4:30 AM.. Of course, the more bulbs/tubes that are on, the more power is used.. One big advantage to the "jump start" units is that you can hook up the battery cables and reverse feed power from your car battery to the unit to get a fast recharge on the jump start battery while actually out collecting.. The really nice thing about a 36 watt unit, is that it is a good size to be used with a display case at home AND also out in the field.. Microscope lamps.. I do make a lamp fixture for use with a stereo microscope.. The current version is custom manufactured with two 9 watt bulbs positioned side by side for a higher energy density.. These UV A tubes/lamps emit a wavelength of 368 nm because that is a good wavelength to make the hydrocarbons fluoresce.. Approximately a dozen of these lamp fixtures are currently being used by petroleum geologists to quantify information about oil samples.. Apparently, the color of the fluorescence (ranging from white to a dark yellow), identifies the composition of the oil/wax while the color density distribution tells them the relative ratio of oil to rock.. I make a simple plastic/acrylic stand to hold the lamp in place at about a 45 degree angle shining down onto the microscope stage.. The stand is removable so that the lamp unit can also be used as a hand held device..

    Descriptive info: Fluorescent Collecting.. Fluorescent Tunnel Photos.. The Diamond Joe mine and the Purple Passion mine are both in the same hydrothermal vein consisting mainly of calcite, but having some quartz, galena, and silver ores.. This vein extends intermittently for about 3,000 feet running roughly north and south.. Some time in the early 1900's several prospecting cuts and short tunnels were made along the vein to determine where it was best to mine.. The largest prospect tunnel is located about 1,500 feet south of the Purple Passion mine up on a hill.. The tunnel bores horizontally through soft koalinized granodiorite for about 40 feet to access the vein.. This tunnel turns left for about 40 feet along the vein.. The walls and  ...   then used some software to stitch the photos into one long loop.. Harvey did a great job - this is an amazing sight, although not quite as good as being there in person.. You may access Harvey's Masterpiece at:.. azminfun.. com/panos/fluores_tunnel.. Click on the thumbnails to see a larger photo.. The Fluorescent Hillside.. The best fluorescent minerals in the vein are actually between the old Diamond Joe inclined shaft and the Purple passion shaft.. When we first started working the vein for fluorescent minerals, the top of vein started about 15 feet up the hillside.. We have worked that area down to about ground level.. This next series of photos shows us drilling, blasting and looking at the fluorescent hillside..

    Descriptive info: Hogan Claim Specimens.. The fluorescent material here typically has calcite (Fl.. red), willemite (Fl.. green/yellow-green), and fluorite (Fl.. blue/violet).. Other fluorescent minerals found in this material include aragonite (Fl.. white/cream), caliche (Fl.. cream/orange), hydrozincite (Fl.. blue-white), smithsonite (Fl.. pink), and two unknowns - one that fluoresces deep pink/rose under SW and the other fluoresces a light blue under SW.. The pinks and the light blue all fluoresce yellow under LW.. We suspect that the deep pink is cadmium rich smithsonite and that the light blue is either lead rich smithsonite or zinc hydroxide.. We have also seen some small spots of bright orange that we suspect may be clinohedrite.. Testing is underway to figure out exactly what  ...   On Sunday October 25, 2004, we mined a large museum specimen of this material with 7 or 8 fluorescent colors..
