I have yet to see a high powered red actually at 650nm. Virtually everything I've metered is either under 642, over 660, or 2mW.
I can’t speak for Rick, but I’m going by what he says and I’m guessing he’s calling them that which the manufacturer is calling them. So variance, I’m sure there some. But 4 watts plus of red, got to be a sight to see. :drool:
