Sharp (brand) LEDs. Check out these numbers!

http://www.sharpleds.com/megazenigata.html

6500K CCT with a 90CRI (and available over 2000 lumens). AMAZING!

Not terribly efficient, but I really want to play with some. Color rendering has been a problem for single-color-die LEDs, but these bad boys sound promising.

How does it compare to the Cree XM-L's?

Good to see some higher wattage LEDs coming out. Not extremely useful for most common sized planted tanks, but could be nice replacements for other lighting applications. Or for very large tanks, instead of HQI's (if the angle is wide enough).

Those look very impressive, except for the name - Mega Zenigata? A row of these over a 3 foot high tank, mounted perhaps 2 feet above the top of the tank, could be a real breakthrough.

I hope they will provide a spectral distribution graph soon, and it would be nice to have a ballpark estimate of the prices for them. The chart they show to demonstrate the good CRI is a little confusing to me.

Depends on what you are comparing. They are very different. The Crees have much higher efficacy (lumens/watt). The Sharps have much better color rendering. The crees have a smaller footprint and can take more heat. The sharps are shorter and have wider light spread. Etc.
