To dissipate heat generated when the lights are illuminated, the housing is designed with ventilation holes. Under significant temperature or humidity variations, condensation or minor moisture accumulation may occur inside the lens. This moisture will naturally dissipate during subsequent use of the lights and is considered normal operation. Please contact us immediately if any functional abnormalities occur. 【High-Quality Construction | Waterproof & Durable Design】Built with reinforced materials to withstand harsh weather and resist moisture penetration.
