i'm using the XML's becuase they are the most ligh for the watts. and becuase really cant any other stuff I found some 10w an 5w reds but thos gota be tro strong.
the old cree's seem like they waste lots of power for the light you get.

that one claim 5W but its on 2.5v @ 1amp = 2.5W
my question is, what xm-l BIN is the in the 660nm area? it should be around the 2700K area. I know one is really "light temp" and once is wave length.
one of those bins for xml have to be close (see the warm chart in page 7 on my first link above) i have found the xm-l for 5-8$ each on website around the net.
