Red and Blue LED Gro Lights--Anyone use?
I have been seeing these on ebay. Anyone using a version of them? 110V 168 bulbs to 900 bulb versions depending on suface area to be covered.

Too Red
I would avoid this light. Per the specifications, it has the following mix of LEDs:
30 Blue light LEDs: 465nm (nanometer) wave length 138 Red light LEDs: 650nm (nanometer) wave length Note that it has much more red than blue which makes it more suited to terrestrial plants. For zooxanthellae, you need more of the blue spectra:  Source: Photobehavior of stony corals: responses to light spectra and intensity O. Levy*, Z. Dubinsky and Y.
