How to choose led wall light

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 the growth period, the higher the value, the more power saving.

2. Color rendering index: The color rendering index mainly reflects the authenticity of the color of the object after being irradiated by light.
