LED Grow Lights offer the most advantages of any indoor garden light. Unlike HID (High Intensity Discharge) lights like HPS (High pressure Sodium) and MH (Metal Halide), LED Grow Lights do not contain any harmful chemicals like mercury. LED Grow Lights also operate hundreds of degrees cooler than HID Grow Lights, reducing the number of crops one loses to heat stress each year. LED's produced narrow wavelengths (colors) of light, which can be combined and calibrated to match the wavelengths plants use most efficiently for photosynthesis. HID Lights on the other hand produce a full-spectrum white light, much of which (up to 70%) is unused by plants. By using LED's of the proper wavelengths, and combining them into precise ratios, plants can absorb up to 100% of the light they emit! This allows the gardener to replace HID lighting with LED Grow Lights, while saving hundreds of dollars on electricity and bulb replacements each year! LED Grow Lights also eliminate the need for bulky ventilation equipment, and often time allow the user to garden stress-free without the need of an air conditioning unit!
Quantum LED Grow Lights from Grow Stealth LED take LED Grow Light technology a step beyond photosynthetic science, focusing on the Quantum Efficiency of plant growth. Quantum efficiency addresses the number of photons required for the formation of one oxygen molecule in photosynthesis (a byproduct of CO2, Water, and Light). Scientists have long believed that light in the 500-600nm region of PAR is unusable by plants, however new research suggests that light in this region plays a vital role in growth times, yield, and photosynthetic efficiency. Research published by NASA confirms that when the 3 regions of PAR are properly balanced (400-500nm, 500-600nm, & 600-700nm), growth times and fruiting yields can be significantly altered. In one study with tomatoes, scientists reduced the entire growth cycle from 130 days to 100 days, while increasing the yields by 30% at the same time! Grow Stealth LED is the only company to incorporate this advanced science into their LED Grow Lights. Their lights also feature high-power 3W LED's, with intensified 90 degree lenses for added light penetration to enhance photosynthesis. So if you're searching for a new light for your indoor garden, try Quantum LED Grow Lights from Grow Stealth LED and make your plants happy!
