I think that part of the fun of doing this is learning and applying it. Came across a thread were the guys using a parabolic reflector with the bulb point down, The thing about parabolic reflectors is will put the light evenly over whole box, it shaped like an umbrella. The guys in the Uk use them alot. The batwing style Half the light shines and the half reflected with the parabolic one all the light shines down and also is reflected. What do you about that? I value your opinion, because look at stuff a little different then me and can poke holes in my theory, which is important, saves wasted energy and time...rw
