yes, you mentioned it quite clearly in your first post. 5000k and 8500k is the color temperature (k = kelvin) of the light produced. havent you learned this in one of your science classes? but yeah when it says the bulb is "8500k HID" theyre just hyping it up. HID my ass. its just a dim white light that is produced. do some research, youll find that cheap bulbs are a waste of money.
