PAR30 35 watt LED plan grow lights, E27 Edison socket standard medium screw base. It mixed red color and blue color, The radio R&B=3:1 (1:1 available too), The light output: the blue 460nm light, Red light 630nm light. Mains voltage operation (Input between AC 85V and 265V). Dimension: 95mm diameter, 129mm high. Material: Aluminum.
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. If this bulb as outdoor lamp, The fixture must be water-proof.
