GE® LED grow light with Balanced Light Spectrum(TM) for seeds and greens is designed to fit your plant's growth stage. GE's grow light uses a balanced spectrum with a red: blue ratio inspired by best practices of professional growers. The balanced spectrum allows not only chlorophyll but also other plant pigments to optimize their light-harvesting. Compared to typical purple grow lights, the light features high PPF (Photosynthetic Photon Flux) to provide more light for photosynthesis and growth. This PAR 38 bulb uses 32W of energy and provides a balanced light spectrum ideal for seeds and greens. High Output PPF of 50 micromoles per second.
