Hello. Often when I buy led bulbs from china, the light color is dirty and has the wrong color. I have often bought warm white and often received light with too much green color or something that looks like dark yellow light. The problem is that when you find something, almost all shops with light products sell the same thing. You don't know what you're getting. Many home ceiling light bulbs now HAVE EXTRA warm light color which is too dark yellow. In my car I have LED. in the middle of the roof of approx. 4000k color you cannot change, and glow bulb in mirror, makeup light that is impossible to find in 4000k color and which does not shine extremely brightly. And has a flat smd LED bulb on the right side. w5w bulb sits horizontally. I know about a bulb but it only comes in 6000k light color. I don't want 10 different light color shades in my car!
