Sylvania 40023 ULTRA LED Grow Bulb allow you to grow plants indoors all year long with little to no sunlight needed. The A21 grow bulb comes with a medium E26 base fitting the standard household light socket. Works great for all stages of growth (germination, growth, reproduction, pollination, and seed spreading). The light bulb is designed to provide a wide light spectrum to encourage healthy plant growth and more yield. Low heat emissions allow for placement close to plants with no leaf burn. Damp rated for high humidity applications.

Sylvania LED Grow Lights provide a wide spectrum of blue, yellow and red light from 400nm 730 nm.
