9 Watt UV -Field Light
 
 
Dual Bulb UV Lights
 
 
Display UV Light
 
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.

We currently have models from 9 watts to 190 watts. The bigger units operate on 110 volt AC, 60 Hertz power, but can be custom made to operate on 230 volt AC, 50 Hertz as well, please ask for a quote.
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). The enclosures for the 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).
*** Ballasts ***
A few years ago, Way Too Cool switched over to hi-efficiency, electronic ballasts for all of the 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. Further, in both the AC and DC versions, they use 13 watt ballasts to drive the 9 watt bulbs. The SW bulbs are rated by Philips to have an average life of about 10,000 hours. Using a stronger ballast greatly increases the amount of UV that is emitted by the bulb, but it does shorten the life of the bulb somewhat. The 9 watt PL-S bulbs, have capacitors built into the base of the bulb to allow them work properly with the magnetic ballasts. The DC lamps use a different kind of ballast and the capacitor is not needed, so I take the capacitor out of the base of the bulbs used in the DC lamps. The reflectors are made from highly polished aluminum. The short-wave (UV-C) and mid-wave (UV-B) models feature Hoya filter glass (U-325) for the very best in ultraviolet transmission and resistance to solarization
*** Special Bulbs ***
These Phillips bulbs 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.
Although the big lamps can be taken out 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.
