1, the power size:
The power of the wall-washing lamp determines the projection distance, generally, there are 18W, 24W, 36W, 48W and other parameters. But the power is not fixed. Power can be flexibly changed according to requirements! General high-power LED wall washer lights are single-row, multi-row is called Linear LED Floodlight!
2, the voltage:
LED wall washer voltage can be divided into DC and AC AC, the general built-in external AC220V power supply (Japan AC110V) mains and so on, external words are generally low-voltage DC24V, DC12V, DC27V and so on. According to different requirements, different manufacturers, the voltage is also different.
3, IP protection class:
This is an important parameter of wall washer, but also the impact of the current quality of the important indicators of the quality requirements of the waterproof level should be above the IP65 is the best, but also requires a related pressure, resistance to fragmentation, high temperature resistance, , Anti-aging grade.
4, the color specifications:
Sub-colorful, full-color, monochrome.
5, color temperature:
(Warm white) 4000K (incandescent) 6000K (white) 7000K (cool white)
6, the light angle:
LED wall washer its light angle is generally narrow (about 20 degrees), the (50 degrees), wide (120 degrees) three, at present, the light era high-power LED wall washer (narrow angle) Effective projection distance of 5-10 meters.
7, the working temperature:
Because the wall is usually used in outdoor lights are more, so this parameter is more important, the temperature requirements are relatively high, the general situation we require outdoor temperature -40 ℃+60 ℃can work.
8, the control mode:
LED wall washer for the current there are two control methods: internal control and external control two. Internal control is not an external controller, the designer of the control system designed in the wall inside the wall, the degree of effect can not be changed. External control is an external controller, the effect can be adjusted by the master key to change the effect. Usually in large projects above, the customer can change their own requirements, we are using external control this program.
Glass reflective lens, light transmission rate of 98-98%, not easy to spray, can resist UV radiation.
10, light source:
Generally use 1W, 3WLED as a light source, but the technology is not mature, the current market with 1W more common, because the 3W heat, heat loss to do bad bad light faster.
