how much vats? (w) .. i dont know if reflector like this could handle the heat from HPS
nickfury, i suggested something like this. this is idea for ballast, he deffenetly shouldnt use cardboard for HPS.
anyway, its pretty hard to burn cardboard. lights would make it crispy and it would crisp apart, but deffinetly not burn![]()
...ballast for light bulb
yea its alot cheaper to bye one
read this...then tell me how your little cardboard box would help him out..and what it has to do with a ballast.......
