COB 4WATT 4000K netural white LED bulb

COB LED is a new technology for LED lamps. Compare to point LED source, Chip on board give out more comfortable light, no spot, no glare. And the risk of the cob lamps to eyes is one level.

Luminous flux of 4W MR16 bulbs can be 240lm. We use cree,itswell,osram,epistar led. Customized requirements are also available.Our hotsellling product is COB-MR16-5W &COB-MR16-3W They are widely used in home,hotel,club,office and restaurant.

1. Over 80% energy saving than incandescent or halogen bulbs
2. Lifespan is over 50,000 hours.
3. No flickering. Good for human eyes.
4. No RF interference or UV radiation.
5. Special design for excellent thermal management
6. Top quality CREE LED available.
7. beautiful design with China Patent.
8. vibration and shock resistance.
