DIY Reflector?

[smellsfishy]

I was out shopping with the family being annoyed i wasn't able to finish my tank setup, and it hit me, 12$ later and 6 months use i see no need to replace them they work so well, not bad for a cheap substitute until i could afford better. Notes: i was able to attach them to the flashing which lines my hood thus no heat transfer problems, i wouldn't just screw them into wood. and the placement of the center of the bulb to the center of the bowl is important. I used the 13" ones and the most non scratched and refletive ones i could find, the sharper your refletion the better.
