90W UFO Hydroponic Lamp plant Grow Light Red Blue LED,WITH 70PCS RED PLUS 20PCS BLUE ULTRA BRIGHT LEDS,WaveLength - Red=660nm, Blue=460nm
1) Powerful 90w led grow light to replace 2 pieces x standard 400W to 600W HPS grow light, save 90% on electriciy.
2) Lifetime over 50,000 hours
3) Use only the exact spectrums required for plant photosynthesis
4) Built-in ventilation fans with a "easily removable" feature so that when a mechanical problem happens with the fans, it can be replaced independently!
5) Built-in thermo-sensitive devices cut off power supply when over-heating happens, either due to high ambient temperature or ventilation fans problem.
6) The low heat emission eliminates the need for ducting & heat exhaust fans
7) Ideal for all phases of plant growth, and works well with any indoor garden, whether hydroponics or soil based
8) No setup required - this is a plug-n-play grow light
9) Each light covers 18 square feet
Applications: Horticulture & Hydroponics Lighting
Cover material: flame retardant PC

he below information may be of help when selecting LEDs for your project.when you choose led grow light , the most import thing is about Lumen ,

200 - 280 nm UVC ultraviolet range which is generally harmful to plants. LEDs in this spectrum are non-existant or very expensive.

280 - 315 nm Includes harmful UVB ultraviolet light which causes plants colors to fade. UV LEDs in this range are now available and coming down in price.

315 - 380 nm Range of UVA ultraviolet light which is neither harmful nor beneficial to most plants.

380 - 400 nm Start of visible light spectrum. Process of chlorophyll absorption begins. UV protected plastics ideally block out any light below this range.

400 - 520 nm This range includes violet, blue, and green bands. Peak absorption by chlorophyll occurs, and a strong influence on photosynthesis. (promotes vegetative growth)

520 - 610 nm This range includes the green, yellow, and orange bands and has less absorption by pigments.

610 - 720 nm This is the red band. Large amount of absorption by chlorophyll occurs, and most significant influence on photosynthesis. (promotes flowering and budding) The ratio of red (660nm) to far red (630nm) in sunlight is about 1.2:1

720 - 1000 nm There is little absorption by Chlorophyll here, but Phytochrome uses a nice portion. Flowering and germination is influenced. Near and above the higher end of the band is the Infrared spectrum, which can also be heat and could cause elongation or affect water absorption/transpiration.
