Specification:
280nm ~ 315nm influence on morphological and physiological processes is minimal
315 nm ~ 420nm chlorophyll absorbs less impact photoperiod effect, prevent stem elongation
420 nm ~ 500nm (blue) chlorophyll and carotenoids absorbed the largest proportion, the greatest impact on photosynthesis
500 nm ~ 620nm dye absorption rate is not high
620nm ~ 750nm (red) chlorophyll absorption rate "high", has a significant influence on photosynthesis and photoperiod effect
750nm ~ 1000nm absorption rate, stimulate cell elongation, impact of flowering and seed germination
> 1000nm converted into calorie
Attention:
It must need a heatsink aluminum for cooling, do not light it without heatsink aluminum.
