1、 Degree of protection
This is also an unavoidable factor in choosing LED wall washer lamp. Strict requirements shall be carried out during selection. LED wall washing lamps shall be used outdoors, and the waterproof grade shall be above IP65 It is also required to have relevant protection requirements such as pressure resistance and impact resistance, so as to ensure the waterproof and dust-proof ability of the lamp under the conditions of wind, rain, sun, etc.
2、 Control mode
At present, there are two control modes for LED wall washing lamp: internal control and external control. Internal control means no external controller is needed. The designer designs the control system in the wall lamp, and the degree and effect cannot be changed. External control is an external controller, whose effect can be changed by adjusting the key of the main control. Generally, for large projects, customers can change the effect by themselves. We use external control. There are also many wall washes that directly support the control system of DMX512.
3、 LED light source
In order to achieve the desired effect of lighting, it is necessary to pay attention to the different design of different lamp beads in the selection of light sources, and the heat dissipation effect is also different. Of course, the light efficiency is also different. It is not possible to select some low-grade and low brightness lamp beads to top up in order to save costs. Whether the brightness of an LED wall washing lamp reaches the standard depends entirely on the light source.
