Aluminum foil once "wrinkeled" does not reflect light with any efficency. What it tends to do is create "hot spots". Pharma' words while maybe sounding critical, were meant to direct DSchwiz in a maner where his money is best spent. Dont take it personal there is always someone who knows more shit than the next guy. And Im usally the next guy! I try to post answers or links when i can help, but there are times when I get "corrected" and im glad i do.....so i can learn.. And while were all trying to help, DSchwiz hasnt followed up yet(lol),
