High power LED Wall lamp luminous efficiency of over 100 LM/w, more because of the LED spectrum is concentrated almost entirely in the visible band, far more efficiency than incandescent bulbs and are catching up with energy-saving lamps and fluorescent lamps.
As the spectrum without ultraviolet and infrared light, no heat, no radiation, not to give burden to the human eye, not as objects fade.
Compared with fluorescent lamps, high color rendering index of high power LED lamp, usually around 80. Photo color is better.
Low maintenance costs:
LED life is long, luminous flux half-life of more than 50,000 hours or more, for more than 30 years of normal use. Strong resistance to impact and shock, no tungsten wire, glass and other easily damaged parts, non-normal "scrapped" the possibility is very small.
Enables lighting small and exquisite, more suitable for use in different places and different arm can be installed so rich in lamps and light.
