Feit Electric's 14 in. LED Full Spectrum High Bay Grow Light uses 86 watts of electricity and comes fully assembled. 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. Built-in long-lasting 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.
