Advantages of LED Grow Lights

LED technology has progressed in recent years. The development of diodes has advanced sufficiently that they are able to emit enough energy for plant cultivation. Light is emitted by the diodes in a specific nanometer range that can be controlled for the most efficient growing conditions. Unlike HPS lights, LEDs can produce all of their light in the photosynthetic active radiation (PAR) range.

The use of LEDs for plant production was first successfully tested by NASA. Since the early 1990s, LED lights have been used in specialized horticulture. They were billed as a promising alternative to high intensity discharge (HID) lights. Many LED lights have not lived up to these expectations, as horticulturalists have noted poor flower growth. However, this is due to poorly designed and manufactured products, not to the LED technology itself. For LED grow lights to be effective, they require a combination of light intensity and a correct balance of light spectrum. The design of our Grow LEDs addresses this combination. Our products revolutionize LED grow lights.

LED stands for ‚??light emitting diode‚?Ě, which is basically an aluminum chip wrapped in silicon. The chip is impregnated with an anode and a cathode. When a current of electricity passes through the chip, electro luminescence is released. The light emitted by LED bulbs is measured in nanometers (nm). These numbers are found in the photosynthetic active radiation (PAR) zone between 380nm and 700nm, which is the viable light spectrum. Although LED bulbs are rated by their peak nm intensity, they can emit light of both higher and lower frequencies. For example, an LED chip rated at 660nm will peak at that intensity but will still emit wavelengths near 640nm and 680nm.

Any wavelength of light can be produced using an LED chip. A few LED companies, such as Osram, Cree and bridgelux, have made Hi-power LEDs (HPLED) that can be driven at hundreds of milliamps (mA) and emit large amounts of light. Most LEDs are only driven at tens of mA, and emit significantly less energy, mostly because other grow light companies tend rely on outdated, cheaper chip technology.

LED Intensity Measurements
Don't be confused by the fact that the 1000 watt HPS light has, typically, 140,000 lumens, which are a measure of a light's visible brightness. The brightest light is emitted in the yellow, green and orange spectrum of light, which is not well absorbed in the PAR zone. For the purpose of growing plans, light must be emitted in the red and blue spectrum. Most of the lumens from an HID light are wasted because they can't be utilized for photosynthesis. The LED lumen measurement may be less than a 1000 watt HPS, but our LED's emit more usable light.

Light Spectrum and Absorption
When horticulturalists use the 1000 watt HPS light, there is a significant waste of heat and electricity because much of the light intensity is not being utilized by plants. Vegetative growth requires blue light, and dense bud development requires red light, particularly deep red in the range of 660.

Our goal is to supply commercial growers the brightest light possible, with the energy efficiency of LED technology. Growers can expect to produce the yields they were able to achieve with a 1000-watt HPS. LED Grow lights are designed with 3-watt Hi-power chips that offer spectacular intensity. We do not use the weaker and less expensive single watt LED chip used by many LED grow light companies. Instead, we bring you the highest quality LED grow light on the market.

Our high quality lights combine the ideal spectrum range with 2-watt chip intensity. Our lights provide the ideal ratio of blue, red, deep red and full spectrum light. You will be pleased with the results when you use the best LED grow light panels available.
