Designed to fit your plant's growth stage. Advanced red light spectrum. For flowers & fruit. Recommended For: Flowering. Fruit production. Non-dimmable. BR30. Medium Base. Light Appearance: White to the eye. High output PPF 15 micromoles per second. Grow your plants like a pro. Our light offers an advanced red light spectrum that allows plant pigments to optimize their light harvesting. Compared to typical purple grow lights, it appears more natural to the human eye, so you can use it in any room without disturbing your family or neighbors. It allows you to appreciate your plant's beauty and makes it easier to spot any pests or discolorations, so you can make sure your plants stay healthy. Advanced Red Light Spectrum: GE's grow light delivers an advanced red light spectrum inspired by best practices used by professional growers. It allows plants to maximize the absorption of light needed for their growth stage. High PPF Output, Better growth: A grow light's power is measured differently. What matters is the Photosynthetic Photon Flux (PPF), measured in micromoles per second. The higher the number, the more light the plant gets for photosynthesis and growth. Our light is designed to maximize the PPF with an advanced red spectrum to give your plants great tools for growth. GE's grow light pleases your plants and your eyes.
