LED wall washer, literally understood, is to make the light shining on the wall produce a wash-like effect. It is mainly used as decorative lighting to outline the outline of the building wall. In recent years, the rapid development of LED technology, its high efficiency, energy saving, green energy saving, rich colors, long service life characteristics of the lamp, has a great advantage in the wall washer. So after 2014, almost all wall washer lamps have been replaced by LED light sources.

The choice of LED wall washer has the following characteristics:

1. Choose according to voltage and power. The irradiation distance of the LED wall washer is determined by its output power. The conventional power is mainly 18W, 36W and 48W. The greater the power, the longer the projection distance. The greater the power, the greater the output voltage required. The voltage of LED wall washer has two types: DC and AC. Generally it is built-in AC22V, external DC12V DC24V DC27V, etc. The power of the wall washer can be adjusted within a certain range, which is convenient for adjusting the effect.

2. When choosing a wall washer, pay attention to its IP protection level parameters. This is an important parameter that affects the quality of its use. Those with IP protection above 65 are all LED wall washers with better quality. Of course, the overall quality is also related to other parameters, such as pressure resistance, chipping resistance, high temperature resistance and so on.

3. Color and color temperature: The wall washer is generally divided into seven colors, full color and single color, and the color temperature is controlled at about 2700-7000K.

4. Light-emitting angle: The light-emitting angle of LED wall washer is generally narrow (about 20 degrees), medium (about 50 degrees), and wide (about 120 degrees). At present, the high-power LED wall washer (narrow) The effective projection distance of the angle) is 5-10 meters.

5. Working temperature: The wall washer usually works outdoors, so its working temperature becomes very important. If you can't withstand too high temperature, then the practicality will be greatly reduced! Standard LED wall washer outdoor work stability is generally controlled at -40 degrees-60 degrees.

6. Control method: There are two control methods for the wall washer, which are internal control and external control. Internal control is to design the program directly in the lamp, it cannot be adjusted externally, and the lighting effect is fixed and cannot be changed. External control is to link the controller externally to the LED wall washer, and the illumination effect can be adjusted through the control. The user can choose the control method for more specific applications.
