this cfl setup

Initially, I did find those claims exaggerated. T5's to compare to a 400W HPS?! And then I did the math. It's true. Amazingly, they're telling the truth.

There are two sides to this. Positive side, less energy consumption and no need for an expensive ballast. Negative side, lots of lamps to change, lots of room occupied by this lamp.
