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!

Very happy with these bulbs. I replaced both these bulbs and the ballasts on my Avalon. The ballasts were making a hissing sound after 7 years of use. The bulbs gave my headlights a sharp cut-off and extremely bright hot spot. I thought it was the projectors on my car that were out of date. Turns out, it was the bulbs and the ballasts. The color is a little yellow, but these bulbs take a while to burn-in to achieve their true colors. I am happy with these bulbs and now I love driving at night again.

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.
