Choose according to the working voltage and strength
The illuminance range of the directional wall washer is maintained and determined by its output power. The larger the potential, the longer the projection interval. The higher the power, the higher the intrinsic result voltage. led facade lighting manufacturers ，The intensity of the wall washer can be modified through a certain array, which can easily and quickly modify the expected results.

Observe the main parameters of its IP waterproof platform.
It is indeed an important parameter that affects its level of use. IP security guards above 65 are very high-quality directional wall washers. Obviously, overall good quality can also be related to other major criteria, such as the level of resistance to compression, amount of resistance to breakage, amount of resistance to temperature, etc.

Selection of optimal color and directional tinting temperature
LED wall washers are usually divided into color, fantasy and monochrome, and the temperature with lampshade is controlled at around 2700-7000K.

Choose a viewing angle
Guided wall washers generally have three viewing angles: narrow (about 20 degrees), medium (about 50 degrees), and wide (about 120 degrees). The far powerful chuck has a range of 5-10 meters.
