my understanding is CFL's are T5's in a spiral ...the price of some higher end 4x54W T5's is dropping fast, you can get good lumens out of a $100 Hydrofarm unit and even more from a $200 TEKive been wondering about peoples custom cfl setups but im no electrician and not that good of a builder. Was just going to switch to t5s, but subbed to this thread hoping i find something good! i dont have any light contraptions just use hanging cfls with the reflector on it from hd
