Product Detail
4w COB LED Bulb
Aperture: 240 lumens ; Size:D50*H58mm
Light color: Cool white 6000 Kelvin
COB LED 4w 6000k cool white LED spot lamp
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 3W 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.
