LED scrubber

[new2scrub]

has anybody built a led lit scrubber that works well yet? with all the new hi powered led's coming out with colors like neutral white,warm white,red, and green,and the wide range of optics, i would think some combination of leds would work well for growing algae,not to mention the savings in bulb replacement and power.

Depends on how you define "well".

My opinion :"Well, but not perfect" and expect it to be trickier than you think.

I have been running an LED ATS for over a year now.
Works better than the standard CFL bulbs did, I but never compared it with a T5 setup.
Zero nitrates/phosphates.
I still have nuisance algae, so not out-competing that.
I have a horizontal ATS though, so less efficient there.

what kind of leds are you using? what color? pic?

BTW: The short version:
You want N * (2 red, 1 blue, 1 warm white)
Exact vendor is not important, but the more efficient the better.
Where total wattage is about 1/4 to 1/2 of recommended for CFL.
