Excellent thread Doc !!! I have many, many questions on cfl's. I have a very small space (3' wide X 2' deep X 7' tall) and my issue is heat. Are there any benefits to using cfl's like these versus a flourescent tube set-up. I was looking at using a 2' 6 lamp on top and a 4' 4 lamp on EACH side of the above mentioned room.

Also, I don't want to highjack your cfl thread but where can I find info on the difference of a T5 and a T8 light ?? Which is better.

Excellent post again. +++reps given.
