1. The efficiency of LED wall lamps is higher. The luminous efficiency of high-power LED wall lamps has exceeded 100lm/W, and because the spectrum of LEDs is almost all concentrated in the visible light frequency band, the light efficiency is far greater than that of incandescent lamps and is catching up with energy-saving lamps and fluorescent lamps.
1. Luminous efficiency: Generally speaking, the higher the luminous efficiency of the lamp, the more energy-saving. It is generally recommended to choose the luminous efficiency of the LED lamp [lumens (lm) / wattage (w)] to be higher than 80LM/W, such an index It is in a growth period, and the higher the value, the more power will be saved.
