The voltage of the LED wall washer is 220V, 110V, 24V, 12V, several kinds, so we should pay attention to the corresponding voltage when choosing the power supply. In addition, there are 18V and 36V. Because these two transformers are relatively few in the market, It is not easy to match the transformer, so 24V or 12V is generally used for low voltage.
2. Working temperature:
Because the wall washer is usually used more outdoors, this parameter is more important, and the temperature requirements are relatively high. In general, the outdoor temperature we require can work at -40℃+60℃. But the wall washer is It is made of an aluminum shell with better heat dissipation, so this general wall washer can meet the requirements.
3. Number of LED lamp beads:
The number of LEDs of the universal wall washer light is 9/300mm, 18/600mm, 27/900mm, 36/1000mm, 36/1200mm.
4. Protection level:
This is an important parameter of the wall washer, and it is also an important indicator that affects the quality of the current guardrail tube. We have to make strict requirements. When we use it outdoors, the waterproof level must be above IP65. It is also required to have relevant pressure and resistance Fragmentation, high and low temperature resistance, flame resistance, impact resistance aging grade
IP656 means: completely prevent dust from entering. 5 means: flush with water without any harm.
5. Control method:
There are currently two control methods for LED wall washer: internal control and external control. Internal control means that there is no external controller. The designer designs the control system in the wall lamp, and the degree of effect cannot be changed. The external control is an external controller, and its effect can be changed by adjusting the buttons of the main control. Usually in large-scale projects, customers can change the effect by themselves. We all use external control solutions. There are also many wall washers that directly support DMX512 control systems.
6. Color specifications:
2 segments, 6 segments, 4 segments, 8 segments full color, colorful colors, red, yellow, green, blue, purple, white and other colors.
7. Light-emitting angle:
The light-emitting angle is generally narrow (about 20 degrees), medium (about 50 degrees), and wide (about 120 degrees). At present, the effective projection distance of high-power LED wall washer (narrow angle) is 20-50 Meter.
