Without any professional measuring instruments, what tips can ensure that consumers can choose high-quality LED table lamps?
1. Select the color of LED lamp: turn on the LED lamp and observe the color of the light
It is recommended to select the LED light source that emits warm color (yellow) light, and avoid using the LED light source that emits white light, especially the LED that emits dazzling blue and white light.
2. Control the illuminance of LED lights
Many led table lamps have three or more gears: strong, medium and weak. It is recommended to select appropriate gears. Too strong and too weak illuminance will damage vision, especially to avoid excessive lighting.
3. The human eye is the most sensitive and precise photoreceptor. When you feel that the light is very uncomfortable, you should pay attention to it
For example, if the eyes feel that the LED table lamp is dazzling and the eyesight is easy to fatigue, it may be that the color temperature of the LED lamp is too high or the illumination value is too large.
