LED grow lamps
 
LED panel light source used in an experiment on plant growth by NASA. Pictured plant is a potato plant.Recent advancements in LEDs have allowed for the production of relatively cheap, bright, and long lasting grow lights that emit only the wavelengths of light corresponding to chlorophyll's absorption peaks. These lights are attractive to indoor growers since they do not consume as much power, do not require ballasts, and produce a fraction of the heat of HID lamps.[3] There are four chlorophyll absorption peaks and LED grow lights use four different types of LEDs to hit all four peaks (two red and two blue).[4][5] Early LED grow lamps required hundreds of 1 or 2 watt LEDs to be effective replacements for HID lamps. Newer advanced LED grow lamps use automotive grade 6 watt LEDs and have shown similar results to HID lamps.

1. 15W led grow panel is made of 225 little power LEDs. High efficiency,Wide angle, long lifespan and good heat solutions.
2. Built-in power supply, CE approved. No setup required, just simpler and safer plugs
directly into AC120V/220V, no reflector & ballast needed.
3. Use only the exact spectrums (R&B) required for plant photosynthesis.
4. Ideal for all phases of plant growth, and works well with any indoor garden, whether
hydroponics or soil based.
5. Environment-friendly: Don‘t contain the harmful substance HPS & MH have, much less
hazardous waste to deal with.
6. It saves 50% to 90% in energy consumption compared to incandescent bulbs or
fluorescent tubes. Wide angle projection insures uniform leaf coverage.
7. Red& Blue mixture is very good for growing and flowering of plants.
