1. According to the 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 farther the projection. The higher the power, the greater the output voltage required. There are two voltages of LED wall washers: DC and AC. Generally, it has 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. IP protection over 65 is a better quality LED wall washer. Of course, the overall quality is related to other parameters, such as pressure resistance, chipping resistance, high temperature resistance, etc.

3. Color and color temperature: Wall washers are generally divided into seven colors: panchromatic and monochrome, and the color temperature is controlled at about 2700-7000K.

4. Luminous angle: LED wall washer has three luminous angles: narrow (about 20 degrees), medium (about 50 degrees), and wide (about 120 degrees). At present, the effective projection distance of Baxter Lighting's high-power LED wall washer (narrow corner) is 5-10 meters.

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

6. Control mode: Now the control mode of wall washer is divided into two types: internal control and external control. The internal control is directly designed in the internal program of the lamp, and cannot be adjusted externally, and the lighting effect is fixed. The external control is an external link controller of the LED wall washer, through which the illumination effect can be adjusted. Users can choose how they want to control more specific applications.

LED wall washers, literally, are to make the light shining on the wall produce the same effect as washing. It is mainly used as decorative lighting to outline the walls of buildings. In recent years, LED technology has developed rapidly, and its high efficiency, energy saving, green power saving, rich color, long service life lamp characteristics, in the wall washer has a great advantage. So after 2014, almost all wall washers have been replaced by LED light sources.
