This is the LED grow bulb that delivers 50% more spectrally optimized light per watt than other grow lights.

Optimizing photosynthetically active radiation (PAR) to maximize plant growth, the passively cooled bulb delivers 12% blue light (400-500nm) to support strong stems and compact growth without the radiated heat generated by lesser bulbs.

Providing 104° F wide flood optical distribution light that maximizes irradiance when placed close to a plant’s canopy, the bulb provides optimal light for high-, moderate-, and low-light plants.

Dimension 5" D x 4 3/4" Diam. (1 lbs.)
