Extracting light from a semiconductor light emitting diode (LED) device constitutes a well known
challenge. This is mainly due to the high index contrast between the bulk semiconductor medium
(eg, gallium phosphide: GaP) and the surrounding environment like air. For example, in

    LED lighting is a proven light source that provides longevity, optimal spectral control, photosynthetic efficiency and rapid return on investment with reduced total cost of ownership. Its also the most earth-friendly solution for you and your plants. Designed specifically to provide supplementary lighting for greenhouse, SANSI tailor-made light recipes mean faster growth, bigger harvests, and higher quality plants.

    Product Features:
    Patented ceramic LED technology, LED chips are mounted directly onto the ceramic body, no PCB.
    High quality LED light source, high luminous efficiency, 90% of the light can be absorbed by plants and flowers, life expectancy up to 50,000 hours.
    Revolutionary heat dissipation system, high power efficiency and low power consumption.
    High quality aluminum die-casting shell, no fans, no plates. All materials meet the requirements of environmental protection.
    Uniformed light and spectrum distribution. Each LED chip is mounted in a circle providing uniformed light and spectrum distribution.
    Intelligent control on lighting spectrum, individually adjustable Red, White, Blue dimmers allow precise 3-channel spectral control, meeting various plant growth applications.
