OSRAM 66440CBI Xenarc CBI D4S Light Bulb, (1 Pack)

The Osram Cool Blue Intense "CBI" series of HID Lamps has easily out-performed the competitors in all aspects, making it an instant success story. We are excited to announce that they are now available in a Mercury-free version for vehicles with D4S Headlamps.

What makes these bulbs so amazing? Osram's Cool Blue Intense bulbs offer more lumens than the once industry-standard Philips 4300K bulb, but with a higher Kelvin rating of 5000K. Whereas most bulbs lose lumens when their Kelvin rises, the CBI's still manage to give users the benefit of brighter light combined with whiter light - the best of both worlds indeed!

The bottom line is that everybody who uses them agrees they're among the best D4S bulbs ever made. We've never heard a customer complain that their Osram's weren't worth the money, and most of the guys here at TRS use them in our own vehicles.

These bulbs are compatible replacement for all HID/Xenon headlights accepting "D4S" bulbs. They have a 2000-hour lifespan, which can last 6-10 years under average daily use. The 5500K color produces a pure white light, and they meet and exceed OE specifications for measured luminosity and reliability.

In summary, the Osram Cool Blue Intense "CBI" series of HID Lamps is a game-changer in the industry. Its superior performance, long lifespan, and unparalleled customer satisfaction make it the go-to choice for anyone in need of high-quality D4S headlamps. The availability of a Mercury-free version is an added bonus, making it an even more environmentally-friendly option. Whether you're looking to upgrade your vehicle's lighting or simply want the best of the best, the Osram CBI series is the clear winner.
