1.The voltage of the led wall washer is 220V, 24V, 12V, several kinds, so we pay attention to the corresponding voltage when choosing the power supply.

2. Working temperature: Because wall washers are usually used outdoors more, this parameter is more important, and the temperature requirements are relatively high. Generally, the outdoor temperature we require can work at -40°C + 60°C. However, the wall washer is made of an aluminum shell with better heat dissipation, so the general wall washer can meet the requirements.

3. Number of led lamp beads: 2. LED wall washer, protection level: This is an important parameter of wall washer, and it is also an important indicator that affects the quality of guardrail tube. We have to make strict requirements. We use it outdoors and require waterproof level It is best to be above IP65. It is also required to have related pressure resistance, 　 resistance to high and low temperature, flame resistance, impact resistance and aging IP65. 6 means: completely prevent dust from entering. 5 means: flush with water without any damage. , Control method: 4. Color specifications: 6-segment, 8-segment full-color color, colorful color, red, yellow, green, blue, purple, white and other colors. 5. Light-emitting angle: The light-emitting angle is generally narrow (about 20 degrees), medium (About 50 degrees), wide (about 120 degrees), the farthest effective projection distance of high-power led wall washer (narrow angle) is 20-50 meters 6. Mirror: glass reflective lens, light transmittance is 98 -98%, not easy to atomize, resistant to UV radiation. 7. Light source: Generally, 1W is used, because 3W heats up 　 a large amount, the heat dissipation is not good and the light decays faster.

1. Different shapes

    General floodlights are prototypes. Generally, it can aim at any direction and has a structure that is not affected by climatic conditions. It is a lamp that specifies that the illuminance on the illuminated surface is higher than the surrounding environment, also known as a spotlight.

    The wall washer is also called a linear led flood light because its shape is elongated. Its technical parameters are roughly similar to those of LED floodlights. Compared with the circular structure of LED floodlights, the strip-shaped heat sink of LED wall washers is a bit easier to handle.

2. Different lighting effects

    The wall washer irradiates a strip of light, and multiple wall washers are put together to form the entire wall that has been washed by the light. Generally, the distance of light is not far, and the irradiated outline is more obvious.

     The cast light is a beam of light that illuminates the area farther and the area is larger.
