What issues should you pay attention to when purchasing LED lights?
2024-01-19
As consumers who do not have electrical knowledge, how to quickly, simply and effectively choose LED products that meet their needs can be roughly focused on the following two indicators.
The first is power and comprehensive light efficiency.
The comprehensive luminous efficiency of LED lights refers to the luminous efficiency of a product's LED lights, and the unit is lumens/watt. The higher the value, the better the energy-saving effect of the light, and the more power it saves. You should choose LED lights with higher lumens/watt.
Choose LED lights with appropriate power according to the use environment. Among the LED lights currently on the market, a 16-watt LED light can achieve a luminous flux equivalent to a 200-watt incandescent lamp, which is enough to meet the lighting requirements of a 10 square meter space.
The second is color rendering index and color temperature.
The color rendering index is an indicator for evaluating the ability of a light source to render color to an object. The color rendering index of a perfect reference light source is 100. The higher the color rendering index, the closer the color response of the light source to the object is to the true color. Generally, the color rendering of lamps between 80 and 90 is considered excellent.
The unit of color temperature is Kelvin (K). The color temperature of general lamps is 2700K-5000K. The color temperature of the light source is selected according to personal preference. For example, if someone likes warm-toned lamps, he can choose lamps with a color temperature of about 3000K.
