I got tired of looking at my crappy, way-too-simple batwing reflector for my cool tube, so I started looking around for better reflectors, but I couldn't find any. So I bought a cheap basic light fixture/reflector for about $30 and used its reflector to sloppily put it on my cool tube. I beat down the middle so it was flat and used aluminum twisty ties to attach it on because I couldn't figure out a better way. It works pretty well and is secure. I figure for $30, if I get two extra grams because of it, I'll be satisfied with that. My question about it is, will it help improve my yield at all by providing better light reflection and therefore more light penetration? Why don't cool-tubes come with or have the option of having better reflectors? I read that cool-tubes have the worst light penetration... could it partly be because of such a shitty reflector? It's a 600w HPS. What do you think? Here is what I had originally, but got annoyed with: Here is what I did and have now: **** RP ONLY
