1. The power of the wall washer determines its projection distance. Its power is not fixed and can be changed according to demand.
2. The voltage of the wall washer can be divided into DC and AC. The built-in power supply is generally an external AC220V voltage, and the external connection is generally a low-voltage DC24V, DC12V, DC27V, etc. According to different requirements and different manufacturers, the voltage is also different.
3. The IP protection level is an important parameter of the wall washer, and it is also an important indicator that affects the quality of the current guardrail tube. The waterproof level above IP65 is the best, and related pressure resistance, crack resistance, high and low temperature resistance, flame retardancy, impact resistance, etc. are also required.
4. Color specifications. Generally divided into colorful, full-color, monochrome. And the color temperature range is wide.
5. LED wall washers generally have three light-emitting angles: narrow, medium and wide. At present, the farthest effective projection distance of the high-power LED wall washer in the light age is 5-10 meters.
6. Wall washers are generally used outdoors and have relatively high temperature requirements. Generally, the outdoor temperature we require can work at -40°C+60°C.
7. There are currently two control methods for wall washers: internal control and external control. Internal control means that no external controller is used, and the level effect cannot be changed. The external control is an external controller, and its effect can be changed by adjusting the keys of the main control.
8. Wall washers generally use glass reflective lenses, with a light transmittance of 98%, not easy to fog, and resistant to ultraviolet radiation.
