As far as plants are concerned, they'd grow just fine with that combination.

As for looks, it would probably look fine as well, just don't overdo the royal blue. 1 to 5 ratio, maybe, and have...

Nearly any Cree or Rebel LED will give you about the same efficiency, for our purposes for a planted tank. I haven't found a source for Luxeon M's but I haven't really been looking for them either. ...

For those interested, this driver would be perfect for 1 Luxeon M, and it would be FREAKY bright. Enough to light a 10 gallon tank by itself, for low/medium level light. You will have some shadows---...

Alright, man, there are several things that need to be pointed out.

First, the XML is an extraordinary product, and so is the Luxeon M, and saying that one "spanks" the other is just fanboy...

I do indeed see these trump the XML in most of our units, but only because it's far easier to find a driver that handles 1,000mA than one that handles 3,000mA. If it weren't for that, the XML would...

You can get the "bridgelux" (lowercase, in quotation marks, because I'm mildly skeptical of the authenticity of these "bridgelux") from Aquastyle, which ships out of Hong-Kong.

Hoppy, if I read you correctly, you are advocating the use of lots of lower-wattage driven (ie, dimmer) LEDs as opposed to using a handful of higher wattage, brighter LEDs, correct?

Their "cool white" is a 5700K which is distinctly warmer than what most other "cool whites" are sold as. Many of the Crees are rated 6500-8000K. It would look just fine :)

I do agree with you that...

DealExtreme is still reeling from the Chinese New Year, this happens every year with them.

Steve's LEDs or Aquastyle.com will be fine, if Aquastyle has some cheap smaller drivers.

According to the specs, you only get 3-4v output, and 1A current, so you have two options. 1 LED per driver at 1A, or 2 LEDs in parallel at 500mA. You'd want one driver per LED.

You could use a 5v wall wart to drive two LEDs but the current level...
