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

Amazing: What makes them so amazing? The Osram Xenarc 66140CBNs offer more lumens than the once industry-standard Philips lamp, but with a higher Kelvin rating of up to 6200K. Whereas most bulbs lose lumens when their Kelvin rises, the Osram Xenarc 66140CBN'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 the Osram Xenarc 66140CBNs agree they're among the best D1S 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 use them in our own vehicles. No matter the preference, we have your Osram HID replacement bulbs!

From Osram: XENARC COOL BLUE INTENSE - discover that modern look at high power!

Awesome Bulbs!!!!!


These bulbs are the best of the best. Very nice light output and they last. They are not the cheap garbage you buy from other places. If you want the true Osram or any other HID bulb buy from the Retrofit Source. They sell only the best bulbs on the market. Not knock offs, it's the real deal. These bulbs may not be the cheapest in price but you definitely get what you pay for. You will not be disappointed.


Clean white light, brighter than stock VW / Phillips HID bulb


I was a little nervous about the higher Kelvin color rating, but they really are a very nice clean white. yes, they have a higher blue component than stock bulbs, but it results in a clean white light and does not appear blue at all. Color closes matches noon daylight on a cloudless day. They took about 8 hours or so to burn-in and reach their full brightness, but one they did -wow! Very pleased.


Still my favs!!


These are crystal white!!! My 1st set lasted about 4 years and developed a lighter flicker (we are talking super light... only noticable on white garage). Got a new set and I didn't realize how much my OG pair had color shifted. My lord is the output on new bulbs insane




Excellent brightness and color quality


Installed these in a 2012 Volkswagen Golf R.

(My install write up with pictures: http://forums.vwvortex.com/showthread.php?8418282-HID-bulb-turned-pink-HID-bulb-replacement)

First off, was concerned about the color quality of the higher color temperature. But they are a clean white light. Yes they have more blue component than stock, but not so much they look blue, they look white, a very close approximation of noon day sun on a cloudless day - very pleased. Once broken-in, they are a bit brighter than the stock Phillips bulbs that came with the car.

Highly recommended.


Such an amazing bulbs!!


Those bulbs are very bright using the OEM ballasts, previous OEM bulbs were not as bright as this bulbs. In short, these bulbs deserves the cash!


You get what you pay for!


If you want a cheap low output knockoff then these are not for you. Go to Ebay and Amazon. If you want brilliant white color and exceptional brightness then these Osram Xenarc CBI D1S are for you. Pricey? Not in my opinion. 100% percent satisfied with these 100% authentic bulbs from The Retrofit Source.
