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 D4S Headlamps!
Amazing: What makes them 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 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 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. No matter the preference, we have your Osram HID replacement bulbs!
Feedback: Don't just take our word for it, read the reviews on HIDplanet!
Genuine: The Retrofit Source is 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!).

Great bulb....i shopped around before purchasing to compare the morimoto d4s, the osram version and the Phillips version. The original factory d4s were from some company named with an "H", they were fairly dull in color around 4k. I swapped out to the morimoto d4s 6500 a few years ago and was easily impressed as this bulb is excellent at its price. One of my morimoto finally gave out and so i began to wonder what the hype is for $170 bulbs. I compared the osram to the Phillips brand and found that the lumens In the osram was overall brighter. Then to narrow down to which osram model. The nightbreakers are too yellow for my preference and the CBH and CBB hadnt hit the aftermarket completely so I went with these the cbi and immediately after installing my wife said that they were noticeably brighter. After a drive last night I could see the difference overall in light output while keeping the pure white look very closely. These bulbs are great and since the cbh and cbb are now available and more costly I'm now more confident in this cbi purchase from the retrofit.
