How to choose LED lights?

How to choose LED lighting products with many types and brands? The inspection agency reminds that the following aspects should be noted when purchasing LED lights:

First, the luminous efficiency: the higher the luminous efficiency, the more energy-saving. At present, it is generally recommended to select the luminous efficiency of the LED lamp [lumen (lm) / wattage (w)] is higher than 80 LM / W, this indicator is in the growth period, The higher the selection value, the more power is saved.

The second is the color rendering index: the color rendering index reflects the authenticity of the color of the object after being illuminated by light. The value is 0-100. Now the LED bulb color rendering index standard is greater than 75. It is recommended to choose 80 or better. It is necessary to purchase a bulb with a high index to reflect the authenticity of the color.

The third is the choice of color temperature: different decoration environments should choose LED lights of different color temperatures. The color temperature range is 2700~6500K, the smaller the value is to the yellow light, the other is the blue and white light. The yellow light is usually used in winter and bedroom, living room, dining room, etc., to create a warm and comfortable feeling. The white light is brighter and clearer, suitable for summer and study, kitchen and so on.

The fourth is product quality: a LED lamp is generally composed of 3 large parts: housing components, drive power, LED. Since the LED lamp generates a large amount of heat, it is recommended to select 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. It is recommended to choose the big brand with warranty LED lights
