Correct Use of Wall Washer Lights

Model Selection: Choose wall washer lights with appropriate wattage and beam angle based on the usage scenario (outdoor/indoor), wall height, and coverage area; for outdoor scenarios, prioritize models with an IP65 or higher waterproof rating and UV resistance, while for indoor scenarios, choose lightweight models with adjustable color temperature.

Installation Specifications: Outdoor installations must be securely fixed, avoiding direct rain and strong winds, and ensuring proper sealing and protection of wiring; indoor installations require adjusting the installation height according to the wall material (usually 0.5-1.5 meters from the wall) to avoid glare from direct sunlight.

Light Adjustment: Adjust the angle and brightness of the light according to the scene requirements. For wider walls, multiple lights can be evenly arranged to avoid light gaps. For decorative scenes, the color temperature can be adjusted; warm light is suitable for a cozy atmosphere, while cool light is suitable for a technological or high-end feel.

Daily Maintenance: Regularly clean dust and stains from the light fixture surface to avoid affecting light transmission. For outdoor models, regularly check the waterproof seal and repair any damage promptly. Avoid frequent switching on and off to extend lifespan.
