Product Description

These lamp fixtures are available only in 110-240 volt AC versions. The ballasts have a switch to select between 110-115 volts or 220-240 volts. The ballasts feature a programmed start cycle that will energize tubes/bulbs/lamps for an average of 50-60,000 on/off cycles before burning out the tube/bulb/lamp. The tubes/bulbs/lamps have 4 pin 2G11 bases. Philips makes tubes/bulbs/lamps that emit UV C and UV A color /10. Philips DOES make a standard UV B in an 36 watt compact fluorescent color /01 version, but it is strictly for medical use and it is very expensive. WTC uses a wavelength transforming sleeve with Nichia UV B phosphor embedded throughout to convert 36 watt UV C tubes/bulbs/lamps into UV B. See Patent #8558203B1. These will do a good job of illuminating a display case approximately 4' wide x 2' tall x 2' deep, but the UV will be a bit weak at the edges of the 4' case. It will be necessary to put bright specimens at the edges.

There were customers who tried to operate the lamp fixtures without turning on the fan because the fan noise annoyed them. This caused the ballasts to turn off because of their high temperature protection and to turn back on when the ballasts cooled off. Eventually, the ballasts stopped working and the lamp fixture was returned for warranty repair. The WTC solution was to change the wiring schema so that the same switch that powers the fan also sends power to the other switches. The result is that the tubes/bulbs/lamps cannot be turned on unless the fan is already on.

The 36 watt fixtures can also be custom manufactured in a "Quad" version with white light LEDs and with a remote control having 5 switches to select between any or all of the wavelengths - UV A, UV B, UV C, White light, and power/fan. Switch #1 turns on the fan and power to the other switches.
