Color Temperature Note - Color temperature 5500K headlight bulbs, including Osram Cool Blue, DO NOT emit a bluish-white light. The actual color is closer to warm white, although it’s whiter than OEM 4300K. Please refer to the images carefully for accurate reference.. The nature of the HID Xenon bulb is that the color temperature shifts over time, becoming whiter as it ages and eventually turning a bluish color before the end of the bulb's life. However, they also lose brightness in the process. This means a USED 4300K OEM bulb might look whiter than a brand-new Cool Blue (CB) bulb, even though it’s producing less light.. Size: D4S. Base: P32d-5. Kelvin: Up to 5500K. Lumen: 3200lm ±15%. Power: 42V / 35W. MPN: 66440CB. Made in Germany
