K7C product features: 1,The two versions of K7C 150W and 110W are quite different, please read this paragraph before ordering to decide which version to buy. 150W has higher power and higher brightne, but we only recommend using it in projector headlights; 110W adopts the design of K5C 110W version, which optimizes the driving scheme and heat diipation system. 2,There is no significant difference between K7C 110W brightne and K5C 110W brightne, and K7C performs better in some projectors. Since the K7C has an extra copper pipe and the upgrade of the cooling fan, the working temperature will be about 8C-10C lower. And K7C's H7 H11 9005 9006 9012 models have added a temperature sensor for the chip position pair, which has a positive effect on protecting the chip from overheating. 3,Some Korean brand cars are not suitable for using bulbs with too high power, please consult us before ordering.
