HQI FAQ:
Q. Why does the arc tube look fired?
A. We test all XDE and XM bulbs before we ship them, thus, the arc tubes were fired. The arc tubes sometimes are left with a silver or smoke look to them, since they ran only a small amount of time, generally less than 2 minutes. The bulb is new, and this dark color generally goes away after the first time you fire it more than a few hours. Over time, most arc tubes turn dark in color at the tips of the arc tube.
Q. The end of my bulb chipped while I installed it. What can I do??
A. Unfortunately, the manufacturer will not accept any kinds of returns for bulbs broken or chipped by the user. With the exception of bulbs broken in transit, we cannot accept any claims on chipped or broken bulbs. We inspect / test all bulbs before they leave our warehouse to insure they are in new condition, and working. Be extra careful while installing these bulbs.
Q. What kind of glass should I use to shield this bulb?
A. Most regular glass will filter out UV rays. Of course, we are not glass experts, so we recommend that you go to your local Hardware Store, Glass Shop or Frame Store to find out which glass will filter the most UV. You can use tempered glass, since HQI type bulbs burn at a very hot temp, but are not required to.
