K8C 40W Product Description:

1. K8C 40W is modified on the basis of K7C, reducing the power of each bulb to 40W and using smaller light-emitting chips. Although the size has shrunk, the luminous flux emitted under the same power has not changed, which means that the light will be more focused.
2. The chip change is not reflected in the H4 model, and the K8C 40W H4 model still uses the same specifications as the K7C.
3. The early version of K8C warm white is more like 5000K. We have recently made changes to the warm white color. The latest version of K8C warm white will be closer to 4300K, they will be warmer than the old color, same color as K5C 40W 4300K. But it should be noted that the warm white color we offer is different from halogen lamps. If you want to order the same color as a halogen bulb, our 4300K ​​bulbs may not meet your needs.
