But the typical pattern seen in spec sheets in almost every bin level is that reds are less efficient as far as radiometric emission is concerned. This is why many companies are using blue diodes as the base of their white LEDs.
According to the specs blue is 45lm to reds 125lm. At least for the 625nm red. The 660 is just given in mW. I dunno. I planned on saving them anyway. Two for sure are dead theyre both 625nm red. Thx Khyber
