    theory of magnifying light...???

I was going to try growing under these lights but the engineer told me they produce harmfull RF waves so I did not. not only that but the little buggers get damn hot. They are pricey aswell for a ballast setup. all glass bulbs no metal. prob need a certain ingition temp. The thing about the cable is it really does not produce light out of the sides and just really out of the ends unless reflected back thru the buffer which is made of like kevlar or nylon. The nylon is nasty shit to work with.

    As far as the glass goes Lumens are decreased every layer of glass they travel through. Light waves can also be streched making a strange or unbalanced spectrum. What that means is beyond me right now, but it sounds like a groovey experiment.

    One love

    Thanks for the reply Karmaxul, I hadn't read it.

I sound argumentative...I'm not smart enough about any of this to be a know it all..just askin. I suppose its not even that great of a diff when you get down to it, but painting for me is so much easier and covers so well, as well as being washable and smells pretty. Thanks guys.
    if you get white paint look for some with a fine metalic flake in it

    Why would you get metalic flake in it?

    A even distibution is ideal in my book

    Are you saying that in theory, one watt of power = 1 lumen?
