Knowledge on LED Wall Washer Lights

Knowledge of LED Wall Washer Lights

1. Power Size: The power of the wall washer light determines its projection distance, with typical parameters being 18W, 24W, 36W, 48W, etc. However, the power is not fixed. It can be flexibly changed according to demand! Generally, high-power LED wall washer lights are single-row, and multi-row lights are called linear LED floodlights.
2. Voltage: The voltage of LED wall washer lights is divided into DC voltage and AC voltage. Typically, they are connected externally to AC220V (in Japan AC110V) mains power. For external connections, it is typically low-voltage DC24V, DC12V, DC27V, etc. Depending on different requirements and manufacturers, the voltage also varies.
3. IP Protection Level: This is an important parameter for wall washer lights and a current significant indicator of the quality of guardrail tubes. The waterproof rating should be above IP65, and there should also be requirements for pressure resistance, anti-breakage, high and low-temperature resistance, flame retardancy, and aging resistance to impact.
4. Color Specifications: Available in multicolor, full color, and single color. Color Temperature: About 2200K (amber), around 3000K (warm white), approx. 4000K (incandescent), about 6000K (white), and around 7000K (cool white). Emission Angle: The emission angle of LED wall washer lights generally has narrow (about 20 degrees), medium (about 50 degrees), and wide (about 120 degrees) types. Currently, the farthest effective projection distance for high-power LED wall washer lights (narrow angle) is 5-10 meters.
5. Operating Temperature: As wall washer lights are often used outdoors, this parameter is quite important, with high requirements for temperature. Generally, they can operate in outdoor temperatures ranging from -40℃ to +60℃. Control Method: Currently, LED wall washer lights have two control methods: internal and external control. Internal control means no external controller is needed; the control system is designed within the wall washer light, so the extent and effect cannot be changed. External control allows the effects to be changed by adjusting the main control's buttons. Usually, in large projects, where clients may wish to change effects themselves, external control is adopted.
6. Mirror Surface: Glass reflector with a light transmittance of 98-98%, not easy to fog up, and resistant to UV radiation. Light Source: Commonly uses 1W, 3W LEDs as the light source. However, due to immature technology, 1W LEDs are commonly used in the market, as 3W generates a large amount of heat, which, if not dissipated properly, leads to faster light decay.
