How to choose led wall lamp

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 [lumen (lm) / wattage (w)] is higher than 80LM / W, such indicators It is in the period of growth, and the higher the value, the more power is saved.

2, color rendering index: color rendering index is mainly to reflect the authenticity of the color of the object after being illuminated by light, the current LED light display index standard is greater than 75, it is best to choose 80 or better, if there is a studio can choose Buy a light bulb with a high index, which better reflects the authenticity of the color.

3, color temperature selection: different environment choice of LED wall light is also different, generally the color temperature range of the lamp is 2800 ~ 6600K, the smaller the value will be biased towards yellow light, and vice versa, the blue light is more suitable for the bedroom, living room, etc. For creating a warm and comfortable feeling. The white light is brighter and clearer, which is more suitable for study, kitchen and so on.

4. Product quality: The LED wall lamp is mainly composed of the outer casing component and the driving power LED. Since the LED lamp generates a large amount of heat, it is better to choose a housing with good heat dissipation. In addition, the power factor of the driving power source needs to be above 0.9; the LED chip directly determines the brightness and decay of the lamp bead.
