Wall washer manufacturer wall washer as a new type of energy-saving light source, the energy saving of wall washer, widely used in commercial lighting, long service life and low price of wall washers are favored by consumers, but everyone knows how much What are the basic parameters of the wall washer manufacturer's products and the precautions when purchasing?
Precautions when purchasing wall washers for wall washers:
1. Commercial lighting brightness (MCD) is different, resulting in different price of wall washers.
2. Leakage current LED is a unidirectional conductive illuminator. If there is reverse current, it is called leakage, LED with large leakage current has short life and low price of wall washer.
3. The LEDs with the same wavelength have the same color. If the color is the same, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.
4. LEDs with different illumination angles have different illumination angles. Special lighting angle, higher price. Such as full diffusing angle, the price is higher.
Basic parameters of LED wall washer:
The power of the LED wall washer determines the distance to which it is projected. Generally, there are 18W, 24W, 36W, 48W and other parameters. But the power is not fixed. Work
It can be divided into DC DC and AC AC. Generally, the built-in power supply is externally connected to AC220V (Japan AC110V), etc. Externally, it is generally low voltage DC24V, DC12V, DC27V, etc. The voltage varies according to different requirements and different manufacturers.
3) IP protection level:
IP65,6 means: completely prevent dust from entering, 5 means: rinse with water without any damage.
4) Color specifications:
Colorful, full color, monochrome
The glass reflective lens has a light transmittance of 98 percent, is not easily atomized, and is resistant to UV radiation.
6) Illumination angle:
The effective projection distance of the high-power LED wall washer (narrow angle) is 5-10 meters, and the narrower the illumination angle, the farther the projection distance is.
