I've pretty much said what everyone else that's bothered to look at the light will say.

Most growers on this forum don't use UV supplement light anyways, HID bulbs emit enough as it is generally.

All gas lights, even filament halogen lights, emit UV. This is why digital photographers still use old non-gas tungsten filament bulbs, as UV screws with your digital camera sensor. my T5s emit UV.

hps and mh bulbs do emitt uvb light but if you have your light in a vented hood with a glass sheild u will loose almost all of the uvb, as any glass reflects uvb, therefore it looses its uv benefits.it has been proven that plants with good levels of uvb will be more potent because the plant uses resin production as a gaurd against uvb rays.hope this helps.

Actually, glass absorbs light. :)
