Some of Cree's new LED emitters have efficiencies over 100 lumens per 
watt and emit fairly strongly in the blue portion of the spectrum, which 
is good for plants. They even come in high-CRI color bins which means 
the fish and plants will show off their true colors. The expense isn't 
too bad when you consider that these LEDs should have a useful life of 
over 10 years on a 12-hour cycle. You could achieve the same lighting 
levels as an AH Supply 55W kit using only 45 watts or so. The issue 
seems to be that nobody is really manufacturing aquarium lights using 
these emitters yet.
