I can't decide which one is the best to use. I found three different bulbs that fit into a light fixture socket. The prices range from $19.99 - $49.99 . The brands are as follows:
(ZooMed PowerSun, T-Rex Active VU heat, Solar Brite UVB Mercury Vapor Globe). The Solar gives off 25 microwatts, the T-Rex gives off 50 mircowatts. What is the least amount needed?
