As a new type of energy-saving light source, LED has been widely used in lighting. Energy saving and long service life are unanimously favored by consumers, but how many consumers really understand the purchase of LED wall washers?
1. The LED brightness (MCD) is different and the price is different. smart lighting fixtures ， The LEDs used in the LED lamps should comply with Class I laser standards.
2. Leakage current LED is a unidirectional conductive luminous body. If there is reverse current, it is called leakage current. LEDs with large leakage current have short life and low price.
3. LEDs of the same wavelength have the same color. If the same color is requested, the price will be high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure color.
4. LEDs with different lighting angles have different lighting angles. Special lighting angles, such as full diffuse angles, are more expensive.
