I am running short of space, so i am thinking to break the exterior glass cover of a 400W MH bulb.
(similar to http://www.allinbox.com/Mod_infocus_X1/Mod_infocus_X1.htm )
I know that UV is an issue. I think that the lcd is not going to be damaged, because i have a condenser lens .
I think that the rest is going to be blocked by the cabinet.
Is it ok?
Full Version: remove glass from MH bulb?
This is never a good idea.

I would agre that this is not a good idea, but there are things that you can do to make the risks manageable.
Build a metal box and put the lamp inside that. The front face of the box should be tempered glass. Lexan is NOT ENOUGH in this case. You want something that can't melt in the event of the lamp envelope failing. The box need not be air tight, but shouldn't have any unnecessary holes in it. You need that to contain any metal salts and/or mercury should the lamp rupture.
Use additional UV filtering. Lexan XL10 is good for this. More UV filtering is a good idea. Even if the LCD itself is protected, any other parts in the back of the projector should also be shielded.
