Features:
1. Red and blue light combination, provide accurate and adaquate light that plant needs in growth;
2. E27 lamp holder, wide range of applications;
Spectral range effects on plant physiology
1. 280nm ~ 315nm influence on morphological and physiological processes is minimal
2. 315 nm ~ 420nm chlorophyll absorbs less impact photoperiod effect, prevent stem elongation
3. 420 nm ~ 500nm (blue) chlorophyll and carotenoids absorbed the largest proportion, the greatest impact on photosynthesis
4. 500 nm ~ 620nm dye absorption rate is not high
5. 620nm ~ 750nm (red) chlorophyll absorption rate "high", has a significant influence on photosynthesis and photoperiod effect
6. 750nm ~ 1000nm absorption rate, stimulate cell elongation, impact of flowering and seed germination
7. >1000nm converted into calorie
