This Dual TripleBright 3 is specifically designed for fluorescent mineral displays where you want two different UV wavelengths, MW and LW370. It comes with special features such as its patented circuits (US patents 6,479,947 and 6,838,837) that allow both lamps to be turned “on” and “off” millions and millions of times without affecting the life of that lamp. The cover is designed so that it can be opened once it is mounted inside the display case. Loosen the one captive bolt and the cover will swing open. The cover is held on by slip hinges so by sliding the cover lengthwise the pins come out of the hinges and the cover can be easily removed to replace the filters if necessary. Most other manufactures of UV display lights have sheet metal screws that have to be removed around the periphery of the cover and you cannot get to the back of the UV light when it is mounted in a display. The Dual TripleBright 3 also has a fan to maintain the optimum lamp operating temperature for maximum UV output.
This Dual TripleBright 3 light has one MW custom designed High Output (HO) lamp (LM-60-312), and one LW370 HO lamp (LL-60-368) that come with the light. Both lamps have a special coating on the inside of the tubing that resists the mercury from penetrating the bulb wall. The special coating allows for long lamp life with minimum UV reduction as the lamps age. The Dual TripleBright 3 comes with two Hoya U-315C SW filters which have the lowest solarization rate of any SW filter. The model DFSL6868 uses two SW FS-60 filters so if one breaks you do not have to replace both filters. The Dual TripleBright 3 uses two 120VAC electronic ballasts that drive the lamps at about 43 KHz for more efficient lamp operation. The light has two custom designed filament transformers that heat the lamps filaments up before it is turned “on” allowing millions and millions of lamp “on-off” cycles. The large aluminum reflector is specially selected from aluminum rolls to have high UV reflection.
