    Hi

    What glass do you use for a metal halide?
    I need to replace one, is it a uv glass and where can I find it?

    Thanks

    Tempered Glass. if you use normal stuff, it cracks first time the MH heats it up.

    Any glass company would sell it, but it's a little bit $$.

    hi

    iv got 2 aquamedic 250w metal halide units. unfortunatly the glass on one is broken, i have found a supplier to get Tempered Glass, the only problem is the glass on the unit 3mm and both the suppliers iv found can only do 4mm. would this matter in anyway?

    thanks

    If a LFS cannot help with a spare, then try Triumph Glass in Alrode.

    Give Shelia a call.

    Triumph Safety Glass

    If 4mm glass will slide into the fitting then there should be no issues. I have had them temper 3mm glass for me before. But if it brakes when being tempered they still charge you. You take the risk.

    However i use 4mm for 150w halides, 5mm for 250w and 6mm for 400w.

    @Jeann1, GSA do not temper glass.

    The glass has to be cut to size first and then put in an oven for heat treatment. Once it is tempered you cannot cut the glass anymore. It will shatter.

    So usinh the 4mm will not weaken the light output in anyway?

    Thanks for your guys input
