Output efficiency is hitting 200L/watt 2x the efficiency of any other tech atm but plasma..
"Ideally" and in a perfect world you would use violet pump emitters w/ RGB phosphors..
Just like tubes and MH...
unfortunately both costs and efficiency of violet based LEd's is not up to the 200L/w...
(Using it because it is the only "industrial" metric to use..)
Hybrids will still be popular due to the geometry of the LED's though I believe this is temporary..
Matter of fact it is really only necessary due to the popularity of puck style panels..
Most panel styles can relatively easily eliminate a lot of the need..
