Elegant appearance, scientific heat dissipation( Aviation aluminum 6063) and optical design, with independent intellectual property and patent, and certificate of CE and FCC. Stable: Wide voltage and constant current drive, no stroboscopic, fast transient response ( no delay), and no damage even frequently switch on and off. Energy saving: above 90LM/W lighting efficiency, and preferable lighting character. At the same illumination, 13w LED Tube light equals 40w traditional lighting, saving 75% power. Life span: LED Tube Light applies low attenuation light source, which ensure 10 times of life span compared to traditional lighting, without maintenance cost and more suitable for fixed situation. Environmental protection: It does not contain mercury and other harmful material, neither the ultraviolet ray, no stroboscopic, friendly to the eyes, no noises which could ensure the comfort and safety when using.
