    Hey people,

    I'm having heat problems. I want to turn my simple open reflector into air cooled one.
    Does anyone know whether I should get some special glass or any simple glass will do?
    Is this a good idea anyway?

    Thanks
    David

    Hey Kevin, why is that?

    because tempered glass has been treated to make it harder to break and more resistant to heat. just google it to find a local glass dealer.

    I used 2mm regular glass.
    Fixed it using heat resisting silicone to the wing reflector I have.
    Used mylar to close both sides (cut 4" holes in each side for air sucking).
    Cheap diy air cooled reflector - works really well. Will post pictures if anyone is interested. :)

    There you go.
    The red stuff is the silicone.

    I am trying to find a glass shop locally that can get me a bunch of 5.5"x12" glass tubes to make cool tubes with. I will post pics of that when its done, it's pretty cool check out my thread for some details.

    Yep, no problems at all. I'm using a 250w hps bulb. The silicone is actually much stronger than I thought.
