Has anyone ever tested the par of a compact fluorescent light bulb like in a room light? I was thinking about changing over to those to possibly save some mula on the electric bill but keep all my plants alive. Currently have 160 watts... IK watts, that was what I was told I needed when I started my tank 6 weeks ago, over my 72 bow (4xT12 6500k). I saw something on youtube about this kid who used Compact Fluorescent light bulbs over his tank and had some good results over the two weeks. Is that a bad idea to change over and does the watts mater on those at all for PAR readings?
