GlowPanel LED grow lights provide your plants with a balanced spectrum of light for healthy & vigorous plant growth. GlowPanels consume 80% less energy than HPS or Metal Halide grow lights and produce virtually no heat. They're great for growing plants and with today's skyrocketing energy costs, they're also good for your wallet. GlowPanels are economical. Less energy used means less of an impact on the environment. The GlowPanel LED grow light lasts 10 times longer than an HPS or Metal Halide lamp and will operate for up to 50,000 hours without the need for costly replacement bulbs. Because GlowPanels do not contain mercury or other hazardous materials they can be safely recycled after 50,000 hours of use.
