D3S: Osram 66340 CBI (5500K) (Duobox)
The Best: An instant success story, the Osram Cool Blue Intense "CBI" series of HID Lamps has easily out-performed the competitors in all aspects. We're excited to announce that they are now available in a Mercury-free version for vehicles with D3S Headlights! Amazing: What makes them so amazing? The Osram Xenarc 66340 CBI bulbs offer more lumens than the once industry-standard Philips 4300K bulb, but with a higher Kelvin rating of up to 6000K. 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! Backed: Bottom line? Everybody who uses them agrees they're among the best D3S headlight bulbs ever made. We've never heard a customer complain that their Osram Xenarc 66340 CBIs weren't worth the money, and most of the guys here at we use them in our own vehicles. No matter the preference, we have your Osram HID replacement bulbs! Genuine: We are proud to offer these bulbs in their original retail packaging from Osram. We pride ourselves on being one of the last few distributors shipping genuine Philips & Osram lamps in the US. It is estimated that 80% of these bulbs sold through outlets such as eBay or Amazon are fakes (even for the new D3S/D4S bulbs!).
