LED wall washer is very common in our lives, which almost depends on their energy-saving and environmental protection functions. It can be used for lighting or setting color temperature in entertainment venues. Since there are many applications on the market, purchases are common. What should I pay attention to when buying? That place is here to explain to everyone:

 1. The application of a good wall washer is mainly reflected in the chip, and money is also a chip. What brand is good? This needs to be determined according to our purchase price. Usually, low-end and mid-end products are purchased every day. In order to achieve commercial goals, in order to obtain the best results, high-end products will be selected.

2. Turn on the light for half an hour, and then check the heat dissipation. If it is very hot, it is considered that the heat dissipation part is cutting corners. Generally, the quality is good and it is almost impossible to generate heat. The energy-saving performance of the lamp is also reflected in its heat dissipation. Compared with the traditional fluorescent lamp, it will heat up after a long time, and the light is warm. However, this kind of LED lamp cannot have this phenomenon, and can also be used as one of the reasoning specifications.

3. Check whether the chip is used under the rated high current, choose to buy 2/3 of the rated high current for use, and the quality is good.

4. View the approximate lumens per watt. If it is lower than 80LM, it is a low-end product, and the light will attenuate faster.

5. Looking at the drive power, it will be treated with glue. The electronic components inside are almost visible. However, we can consult the LED wall washer manufacturer for this efficiency. The efficiency should not be too low, at least it should be greater than 88%, and the PF value of this unit should be greater than 93%. If this parameter specification can be reached, the bulb will not be too bad.
