CBN: For years, the Osram Cool Blue Intense (CBN) was the gold standard for HID bulbs. Now, the CBN name is technically dropped for the "Next Gen" CBN. Long live the king, even with a name change!

The Best: An instant success story, the Osram Cool Blue Intense "CBN" 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 D4S Headlights!

Amazing: What makes them so amazing? The Osram Xenarc 66440 CBN bulbs offer more lumens than the once industry-standard Philips 4300K bulb, but with a higher Kelvin rating of up to 6200K. Whereas most bulbs lose lumens when their Kelvin rises, the CBN'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 66440 CBNs weren't worth the money, and most of the guys here at TRS use them in our own vehicles. No matter the preference, we have your Osram HID replacement bulbs!
