The light source used the high-brightness and high-performance import chips and its operating life is more than 50, 000 hours, energy saving 90% than the filament lamp and 60% than the energy saving lamp.
Using Twelve 1Watt imported high brightness LEDs, this downlight is also available in non-dimmable and dimmable version.
No UV and IR, no mercury, cadmium, lead and other hazardous material, no secondary pollution and less heat, which make the environment cleaner and more comfortable.
Used environmental radiating aluminum, firm housing, better shock resistance and easy to transport.
Don't alter any other parts and install directly same as the traditional light, the special design of lightning protection, over-current protection, over-voltage protection and short-circuit protection benefits your health and property and with CE and RoHS certification.
It is widely used in living room, bedroom, kitchen, washroom, school, university, hospital, hotel, commercial complexes and so on.
