Removing the color wheel or other pieces of glass between the lamp and the dlp chip will shorten the life of the chip significantly (because it doesn't like the UV light and the hinges of the little mirrors will fry)

Hope this helps!

How true is this, really? I have yet to read of anyone destroying the DMD chip even after upgrading to a 20W UV LED and blasting away. I would imagine you are more likely to destroy the DMD chip from all the heat/IR given off by running those bulbs at full tilt. Technically, I believe the datasheets show that using a 405nm LED shouldn't lessen the life of the DMD chip at all. The UV they are talking about is more close to UVB than violet/UVA wavelengths. You'll probably lengthen the life of the chip since you aren't producing so much heat.
