Very Cool LED's!!!

Looks decent but pricey. Would want to see an independent test with PAR measurements to see penetration at depth as I don't see any optics. Also it doesn't look big at about 14" x 8" so I would also want to see coverage as any decent sized tank will need more units (at least the slave units are slightly cheaper). So let's guess one master unit and two slave units for a 48" tank and you're looking at $3000. I honestly don't know why the costs have to be that high. The cost of the LEDs has come down greatly in the last few years.

The various lighting options would not be hard to do with LEDS. Just needs a computer programmer to set it all up. No magic there but it is nice to have all the options.
