Holy crap!
That's an amazingly compact module! Looks to be - what - 8 inches square? Less even? And it's making 20 watts... That's incredible!
Very nice work!
OK, I have to ask: How much for the 20 watt version, and how much for the 12 watt version? (I know they won't be cheap)
Also, can you do a hybrid version with both 462 nm blue *and* 445 nm blue on the same plate, or is it strictly one or the other?
