Not to be greedy or ungrateful, but... It seems like the pace of LED improvements has stalled a bit, doesn't it?
The XM-L is about a year old now, and T6 remains the brightest widely available flux bin.
Luminus has not moved the ball since the SST-50 and SST-90, which are a couple of years old. (The CSM-360 isn't what I mean by new; it's really just a 4 x SST-90 package. The point is, same emitter technology.)
Ditto the rest of the field, as far as I can tell: Seoul P7, etc.
So are we on the brink of a wave of new products, or are we stuck because it's getting harder to improve?
We know that Cree has 231 lm/W in the lab, but how far is this from production?
Anyone have the inside scoop on this? BTW, I get LEDs Magazine and even there it's been awfully quiet lately on the fundamental technology front.
