Right now the Ray2 is powering the back portion of my tank, and it is doing splendidly. The plants back there are getting phenomenal growth, pearls like crazy.
BACK: I have the RAY2 in the back
MIDDLE: Marineland Reef (no timer)
FRONT: Marineland Doublebright
I have since turned off the doublebright and use it only for moonlight
For the price of the Marineland Reef (no timer) in 36 inch, you can buy "2" Ray2s
Avoid the EVO lights on Ebay
