Grow better, stronger plants with the Feit Electric GLP20FS/HB/175W/LED full spectrum grow light. This 20-inch LED High Bay Grow Light uses 175 watts of electricity and comes fully assembled. Rated for high humidity, it is suitable for soil or hydroponic gardens. It can be hung over plants indoors or in a greenhouse to simulate sunlight for vegetative/early growth periods. This no-humming LED emits precise wavelengths and color for superior photosynthetic response in the 450 nm blue spectrum preferred for vegetative growth. Full spectrum LED emits 315 μmol/s of PAR plant-usable light to promote plant growth. Integrated LEDs mean there are no lamps to dispose of or replace. Their relatively cool operating temperature prevents leaf burn allowing lights to be placed closer than high-pressure sodium lamps. It includes two triangle hanging harnesses, as well as a 5-foot plug-in chord and an easy on/off switch. Durable smooth-edge housing and a lightweight design make the installation process easy. Energy-efficient and low-heat, these Feit Electric grow bulbs produce even light distribution and have an average life of 50,000 hours / 47 years. Choose a quiet, dependable general-purpose grow light for your hydroponic needs.
