hey sunbudu3, those lights are only 15 watts...you better buy 200 of them. instead of buying "odor control lights" look of CHILDREN OF BODOM's DIY carbon filter. It is probably the best and CHEAPEST carbon filter fabrication I have seen on this site. Costs about 30 for supplies, a lot for the carbon, but you can use that "crystals only cat liter" in place of the carbon...its like 8 bucks a bag...hope it helps
