LED plant grow light bulbs, The scientist find that the blue 400~520nm light, Red light 610~720nm, Orange 613~620nm are best rays for plant photosynthesis. LED grow lamp provides the right rays. Spectrum-tailored grow light is plant specific and more efficient than incandescent. The Plant LED grow lamp uses LEDs to generate the specific colors of light that plants use most efficiently for vigorous growth and health. Increase florescence time much more. For example, For the flower in vase indoor, The florescence increased to 20 days is not impossible. Especially useful in indoor plant and stove plant. PAR38 E27 Edison socket standard medium screw base with 204 LEDs mixed 90 pcs blue color LED and 114 pcs red color LED. Total 204 LEDs 18.5W floodlight bulb with 120 degree beam, Light output comparable to 150 watt incandescent, Lifespan of up to 60,000 hours, 300~400LM, Input AC 220V/230V.
This bulb glue a cover in front side with glass cement, LED sealed inside the glass, But as outdoor lamp, The fixture must be water-proof.
