LED Technology

Look closely at the wavelengths between 400 - 470 (violet and blue) and the wavelenghts between
610 - 720 (orange and red) in the image below (nm = nanometer):

The red and blue wavelengths of the light spectrum predominantly impact the plants photosynthesis process. Generally, blue enhances vegetative growth, while red promotes flowering. LED grow lamps that contain these light frequencies scientifically manipulate photosynthesis.

200 - 280 nm
UVC ultraviolet range which is extremely harmful to plants because it is highly toxic.

280 - 315 nm
Includes harmful UVB ultraviolet light which causes plant colors to fade.

315 - 380 nm
Range of UVA ultraviolet light which is neither harmful nor beneficial to plant growth.

380 - 400 nm
Start of visible light spectrum. Process of chlorophyll absorption begins.
UV protected plastics ideally block out any light below this range.

400 - 520 nm
This range includes violet, blue, and green bands. Peak absorption by chlorophyll occurs,
and a strong influence on photosynthesis. (promotes vegetative growth)

520 - 610 nm
This range includes the green, yellow, and orange bands and has less absorption by pigments.

610 - 720 nm
This is the red band. Large amount of absorption by chlorophyll occurs,
and most significant influence on photosynthesis. (promotes flowering and budding)

720 - 1000 nm
There is little absorption by chlorophyll here. Flowering and germination is influenced.
At the high end of the band is infrared, which is heat.

1000+ nm
Totally infrared range. All energy absorbed at this point is converted to heat.

HERE’S WHY LED GROW LAMPS AND PHOTOSYNTHESIS GO HAND IN HAND

Here are the advantages and benefits you’ll get from LED Grow Lamps · No special bulky or heavy ballast is needed that eventually burns out and needs to be replaced · Use a simple standard inexpensive light bulb socket · Plants, like trees, best utilize the Blue and Red wavelengths for chlorophyll production during photosynthesis · LED’s don’t produce harmful heat that can injure and burn your plants, or yourself, which can grow right up next to the bulbs better utilizing the space you have · LED’s are extremely energy efficient, will not consume large amounts of expensive energy in comparison to metal halide or high pressure sodium systems, and will save you tremendously on your energy bill · LED’s have long bulb lives ranging from 100,000 to 150,000 hours! · LED’s don’t require any special cooling fans or reflectors as other grow lamps do · Blue wavelengths enhance vegetative growth, while Red wavelengths promote flowering during photosynthesis · LED grow lamps don’t produce the annoying white glare produced by other grow lamps and are compatible to the human eye, your home and plants, providing just the right combination of light energy plants need · LED’s are environmentally safe and don’t contain any hazardous chemical elements, like mercury, found in metallic vapor and florescent lamps
