The luminous efficiency of high-power LED wall lamp has exceeded 100 lm/W, and the luminous efficiency of LED wall lamp is much higher than that of incandescent lamp and is catching up with energy-saving lamp and fluorescent lamp because the spectrum of LED is almost entirely concentrated in visible light band.
The quality of light is high:
Because there is no ultraviolet and infrared rays in the spectrum, so there is no heat, no radiation, will not bring burden to the human eye, will not fade many objects illuminated.
Good color rendering:
Compared with fluorescent lamps, high power LED wall lamp has a high color rendering index, usually around 80. The color of the object is better presented.
Low maintenance cost:
LED has a long life and a half-life of luminous flux over 50 thousand hours. It is generally used for more than 30 years.
It can make the lamp compact and exquisite, more suitable for different places of use, and can install different arms, so that the lamp light changes richly.
