Description: Our LED lamps use high brightness LED chips. The shell comes with great heat dissipation performance, which guarantees the service life of LED . Adopt silicone rubber to strengthen the sealing for high standard waterproof performance of the lamp. All lamps are subject to a 24-hour aging test before leaving the factory; strict quality control before delivery ensures the quality of the lamps. Note: The cool white light is a gray shell, and the warm white light is a black shell.
