    Remember incoherent light radiates from the source (unlike coherent light aka LASER) so only a small portion of the light will be reflected back to the bulb.

    To the mylar store!

    I think I'm going to get a 50' roll. If I have enough left over, I'll be posting some up on the trade board for seeds.

    I once read somewhere (maybe at TF?) that having creases can direct focus the light intensity on a small part of you plant damaging that portion; however, I doubt there is much fact in this since most people are using florescent bulbs anyway and the odds of the crease being such a way that it focuses more light than usual on one specific location is probably slim to nil.

    Someone else's two cents I thought I'd throw in.

    I have always used flat white as a reflector. The diffuse reflector seems to spread the light better. And flat white is nearly 100% reflective.
    There's a tunnel at the end of the light...

    Dyflam is exactly right, flat white is also a good reflector...

    Which leads to the question, which is better... I dunno, but I have an infrared thermometer and just for fun when things warm up a bit I will coat some pieces of Plexiglas with flat white paint, gloss white paint, Mylar, foil and whatever else I can think of... place them all in the sun at the same time and measure the temp variations

    I have always assumed Mylar would be best due to the fact that the high end light fixtures use highly polished metal surfaces instead of flat white, but it would be interesting to see what the temp changes of each surface would be... seems like that would be a good indication of how each surface compares

    Be nice to own an infrared thermography camera

    Where are all our physics majors LOL

    Cheers'
