What Details Should Be Paid Attention to When Purchasing LED Wall Wash Lights?

Currently, low-power LED wall wash lights are widely used in commercial fields such as large-screen terrestrial lighting fixtures. When purchasing LED wall wash lights, attention should be paid to the following details:

1. Coating Process of Wall Wash Light Profiles: The titanium plating process for wall wash light profiles and aluminum profiles is a coating process, which includes additional pre-plating and electroplating processes on the basis of conventional titanium plating processes. In the aluminum profile processing, the electroplated parts are chemically treated in a solution of salt and hydrochloric acid to enhance the quality, thickness, and hardness of the aluminum oxide, make the appearance and the texture of the profiles smooth, healthy, vibrant, tactile, and visually appealing, and select suitable mounting structure styles. The thermal conductivity of aluminum alloy is approximately 50-60% that of copper, which is beneficial for manufacturing heat exchangers, evaporators, heaters, lighting fixtures, radiators, as well as automotive cylinder heads and radiators. Good profile features include corrosion resistance, high thermal conductivity, and durability.
2. LED Chip Light Source Quality: There are many types of wall wash lights in the market, but one quality indicator of LED wall wash lights is the LED chip light source. The chip's color temperature is indicative, and luminosity is crucial. Initially, LED light sources primarily used phosphor. With decades of skill improvements, the luminous power of LEDs has significantly advanced. The luminous efficiency of incandescent lamps and halogen lamps is 12-24 lumens/watt, and that of fluorescent lamps is 50-70 lumens/watt. After improvements, LED luminous efficiency will reach 50~200 lumens/watt, characterized by good monochromatic light, narrow spectrum, and can directly produce colored visible light without the need for filtering. Countries worldwide are competing in researching LED luminous efficiency, which will make significant strides in the near future. Good light sources are characterized by high luminous power, low power consumption, long life, safety and reliability, environmental friendliness, and power factor matching techniques combined with power supplies.
3. Waterproof Grade of Wall Wash Lights: The waterproof grade is an important parameter of wall wash lights and a vital indicator affecting quality, which requires strict standards. When used in sky and land lighting, a waterproof grade of IP65 or above is preferred. It also requires related pressure resistance, crack resistance, high and low-temperature resistance, flame resistance, and impact aging resistance.
