Unlike "broad spectrum" plant grow lights, which produce a lot of light plants can't use efficiently, LEDAgro Grow Lights enhance the colors of light used by plants for efficient and healthy growth. By boosting light plants need and delivering greater intensity through our patented delivery methods we save power and money. Product life is 70,000 hour lifetime marked as a 30% decrease in brightness. The LEDs will still continue to function long after the 70k hour milestone is reached. Each product has a balanced, stress free, light spectrum that allows for 24/7 operation for up to a 40% increase in plant growth. Use as a primary light source, supplemental light, or to extend your greenhouse season to 365 days per year.
