LED wall washer purchase considerations

As a new type of energy-saving light source, LED wall washer has been widely used in outdoor Landscape Lighting. It is energy-saving and has a long service life. It has been favored by consumers. Nowadays, there are many kinds of led wall washers on the market. Innovative, but customers are getting more and more difficult in their choices. What kind of wall washers are better? Qun Yao Optoelectronics tells you about the matters needing attention when purchasing LED wall washers.

Learn about LED lights before introducing them

1, the drive power

A high-efficiency, low-heat, and stable drive Power Supply is especially important for LED Lighting products. LED wall washers are no exception. Now let's discuss the non-isolated drive power.

Non-isolated driver power supply characteristics generally require constant current and wide voltage, that is, the market voltage is 85-265V, which is common, low power consumption, high efficiency, and in some cases, high power factor is required. It has the requirements of open circuit short circuit protection, output overvoltage protection, high load capacity, etc., and also needs to adopt some safe design for the part of the driving power supply, using physical insulation, even when using non-isolated driving power supply. It also achieves absolute safety.

2, LED lamp beads

Look at what kind of lamp beads are used. The LED illuminators are wafers. Different wafers have different prices. The chips in Japan and the United States are relatively expensive, and the prices of wafers in Taiwan and China are generally lower than those in Japan and the United States (CREE).

3, protection level

LED wall washers are required to have relevant pressure resistance, chipping resistance, high and low temperature resistance, flame resistance and impact aging resistance.

Protection level: IP65 - IP67 (IP68 highest) The current light age structured waterproof wall washer has an effect of up to I67, with high waterproof and long time characteristics. Even if it is used for a long time, it will not affect its waterproof performance!! Specifically, you can learn about the waterproof rating of led lamps.
