Q: Why do I need a LED grow light?
A: Compare to HPS/MH lamp, LED grow lights are Energy-saving,Zero heat emiting,No expensive accesories,long life time,higher effeciency,Simple using,Environmental-friendly.
*Energy Saving- LED saves a 60-80% electricity bill than HID lamp.
*Zero heat emiting- LED is cold light source with built in fans for LED chip cool and run well,don't burn your plants.
*No expensive accesories- don't need ballasts, reflectors, air-conditioner which cost your more.
*Long life time- over 50,000hours, don't need replace bulbs or other parts.
*high effeciency- LED only emit useful wavelength for plants growing,over 90% or better effeciency than HID's 35% on output energy.
*Simple using- Plug and play, no need installation.
*Enviromental friendly- don't contain any harmful substance,green hi-technology for our earth.
Q:What is the wavelength suit to my plants?
A:Forms of electromagnetic radiation like radio waves, light waves or infrared (heat) waves make characteristic patterns as they travel through space. Each wave has a certain shape and length. The distance between peaks (high points) is called wavelength.Each shade of light along the visible spectrum can be measured in nanometers (nm) that range from 380nm to about 780nm, from blue/violet to red. spectral region influence the Plant Physiology:
280 ~ 315nm The shape and the physiological processes of little effect.
315 ~ 400nnm Chlorophyll absorbs less, influence light cycle effect, prevent stem elongation.
400 ~ 520nm(Blue) Chlorophyll and carotenoids absorb the largest percentage, the biggest influence on photosynthesis.
520 ~ 610nm Pigment absorption rate is not high.
610 ~ 720nm（Red） Chlorophyll absorption rate is low, for photosynthesis and light cycle effect have notable effect.
720 ~ 1000nm Absorption rate is low, stimulate cell extended, influencing flowering and seed germination In a word, the red,blue,orange is main wavelength/color energy for plants' photosynthesis.
