PHILIPS D1S XenStart HID Xenon Bulb 85415C1 — D1S PK32d-2 35W OEM-grade, 4300K 3200 lm

Philips D1S XenStart 85415C1 is an OEM‑grade HID xenon headlight bulb that restores factory brightness and color for vehicles specified to use D1S bulbs.

Designed and manufactured by Philips in Germany, this XenStart D1S 85415C1 bulb delivers the same light output and color tone many luxury cars left the factory with. It’s a direct replacement for vehicles that require a D1S bulb and uses the PK32d-2 base and 35W power rating common to OEM HID systems. Built to meet automaker approvals, the XenStart line focuses on consistent lumen output, stable color temperature, and reliable fitment so the light you install performs like the original lamp.

How bright and what color temperature can I expect?

The Philips D1S XenStart produces about 3200 lumens (±15%) with a color temperature up to approximately 4300K. That balance yields a white‑warm light that closely matches factory HID tuning, improving visibility without an overly blue tint.

• Typical lumen output: 3200 lm ±15%
• Color temperature: up to ~4300K for natural white light
• Power rating: 85V / 35W for standard HID ballasts

Is this the right bulb for my car and how does fitment work?

This is a D1S‑format bulb with a PK32d-2 base; it is not compatible with D3S sockets.
