Adopting super bright integrated led with multiple chips as light source;-- as the led is closely connected to the crust, so the heat from leds can be dissipated by the aluminium of the housing, and the air cross-ventilation system to ensure the long lifespan and light efficiency. -- the light is sealed with silicone rubber, and the surface of the light is anodized and with spraying plastic technique to be sure of the high protection rank ip65. -- various reflectors to make different high reflecting efficiency to make sure the luminous flux;-- ac driver with plugs ( european, american, british, australia ), easy installation;
