The follwoing is for LUXEONS..not normal LEDs
+high can get very high light density
+last ~50,000 hours (10-15 years+)
+more effectively remove heat
+can use as "spot lights" with a lense
+can do dimming/dusk/dawn
+all sorts of colors if you want to add a little more of a given color
+appears to have a good photosythetic responce overlap
-needs a heatsink
-must DIY some part of it
maybe more +/- ...?
Not sure about wall plug efficiency, but 7watts of luxeons light the tank more than a 7watt PC. Not sure about plant growth, but I am working on that.
