The LEDs I used in my custom fixture produce about 685 lumens each. That's close to a typical 18" T8 flourescent that does 750 lumens.

However, like mentioned, an LED has all that energy focused (in my case, a 120 degree cone) while a flourescent is omni-directional.

Those suckers are so bright they literally blind if you look right at them. I probably should've gone for lower power, and more numerous than just two individual high power LEDs ;) They work though.

The only commercial LED fixtures I've seen that people have had success with and you can easily find in stores is the Marineland Double Bright.
