I put before the LED guru's eyes the following to ruminate and 
disseminate upon.

http://www.epistar.com.tw/

Epistar say they have produced a 110lm/W for 1W and 3W warm white 
LED's. According to them the 1W offering has a CRI (hmm some sort of 
index I suspect) of 90 @ 15v the CCT (I know that one) is 3000K

The LED's are made up of a cluster of blue and red chips with a 
yellow/green phosphor. 

The LED clusters can be fiddled with to allow direct AC drive sourcing 
(not at mains voltage, just thought I'd make that clear).
