6ea 18W T8 fluorescent LED plant grow Light different radio R&B

6 pcs of 4FT T8 18 watt LED Plant grow light tube. It mixed red color and blue color, The light output: the blue 460nm light, Red light 660nm light. Light output comparable to 200 watt incandescent, Lifespan of up to 50,000 hours. Mains voltage operation (Input between AC 85V and 265V). Dimension: 30mm diameter, 1200mm length. 30mm diameter tube with G13 standard base, Plugs directly into fluorescent 2 prong receptacle. As T8, T10, T12 fluorescent tube replacement. Bypass Expensive Ballasts And Wire Direct. See how to install it and replace it.
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.
Different radio R&B option: F01, F04, F21,F31, F41, F51, F71, F91. Please make a comments  when you order it.

Why using Full Spectrum:
Make sure you pick the correct spectrum of light for the growth stage of your plants.
There are two types of light spectrums to look for when choosing bulbs: broad and targeted. A targeted spectrum uses specific wavelengths of LEDs to match the photosynthetic requirements.
The best bulbs feature a targeted spectrum, which may include UV, red light, white light, IR, and blue light.
UV: This spectrum helps with growth stimulation, disease reduction, and promoting sugar and protein.
Blue Light: Helps with the overall plant phototropism work.
White Light: A full spectrum will fill in for any missing spectrums.
Red Light: Suitable for promoting photosynthesis, sprouting, as well as blossom. Also, it contributes to the synthesis of chlorophyll and the formation of flower pigments.
IR: Plays a vital role in the development of heat necessary to ripe fruits.
We recommend you choose a bulb with a targeted spectrum that includes all of the abovementioned spectrums.
