Read this thread: http://www.plantedtank.net/forums/li...ver-bulbs.html From that you can figure out how many of what wattage spiral fluorescent bulbs you would need, with them mounted either horizontally or vertically. You would need a lot of bulbs if they are horizontal, or a lot less if they are vertical. You can't make the decision by adding up the wattages.

If you are willing to use Home Depot work lights, http://www.homedepot.com/h_d1/N-5yc1...atalogId=10053 and 26 watt 6500K bulbs, 3 of them will be adequate.
