I just bought two different led grow lights. Both using the same leds. One is the flat panel type with 225 mixed red/blue leds. And the other is the screw in bulb type with 168 mixed red/blue leds, 30 blue and 138 red.
I'll update later when they have arrived and been set up.
Blue LED light range - 430nm radiation peak athwart a 466nm emission range,
Red LED light range - 662nm radiation peak athwart a 680nm emission range,




I would like to get one of these as well so that I can stimulate flowering in specific parts of the plant while leaving the main lights on above.
