OSRAM XENARC COOL BLUE BOOST is dedicated for the 12/24V car park and can be used in the majority of the cars equipped with HID xenon headlamps.Trust the number one – just as so many international car manufacturers do OSRAM is a global market leader in the field of vehicle lamps. Each year, half of all globally manufactured cars are equipped with our light sources. Our customers also include the largest international automotive companies. Put simply: With OSRAM, you can rely on lighting solutions that always meet ever growing safety requirements and impress with the very highest quality and performance standards.

Review: Nice bulbs, appears to be legit - I just installed these bulbs today and haven't seen them at night yet, but expect they will be fantastic. I had one bulb burned out, so replaced that one first to compare with the other still working bulb. It seemed much brighter (though both still blinded me.) Upon initial start-up they do appear blue/purple-ish and then settle to a very nice white that can be see on the clear headlight housing but still has that 6000K-ish color that I had previously. As soon as I received the bulbs, I went to the OSRAM site and verified the number on the unbroken seal and the two bulb numbers returned matched what was in the package. So I was comfortable proceeding with all the work to remove the front bumper to get the headlight housing out in order to change. The price was very reasonable compared to other sites that wanted over $200 USD for the same set. As long as they are legit, which they appear to be, it's a great deal. I'll update again once I've had a chance to see them at night.

## Questions & Answers

**Q: is this for 1 or 2 bulbs?**
A: 2

**Q: Does anyone know what the osram 66140cbb-hcb typical life span would be ?**
A: I’ve had them since July 2019, so 2.5 years and roughly 40k miles of wear on them and they aren’t as bright as they were when new. I’d say about 85% as bright. I’m considering buying a new set, would definitely buy these again.

**Q: Do they fit a Ford Focus**
A: Look in your Owners Manual or Online to determine the Xenon bulb type.  These are D1S.

**Q: Which vendor to buy from?**
A: We have 100% authentic Osram bulbs.

### ⭐⭐⭐⭐⭐ Nice bulbs, appears to be legit
*by K***. on August 29, 2020*

I just installed these bulbs today and haven't seen them at night yet, but expect they will be fantastic. I had one bulb burned out, so replaced that one first to compare with the other still working bulb. It seemed much brighter (though both still blinded me.) Upon initial start-up they do appear blue/purple-ish and then settle to a very nice white that can be see on the clear headlight housing but still has that 6000K-ish color that I had previously.

### ⭐⭐⭐⭐⭐ CTSV

Great light quality its bright

### ⭐⭐⭐⭐⭐ GREAT CHOICE BUT BE CAREFUL OF PACKAGING
*by J***A on October 16, 2019*

I've went through various HID models between Philips and Osram, both German, and both excellent products; but for the D1S versions my X5 Retro-M needed, the Osram Cool Blue BOOST won out, after countless hours comparing brightness readings, warmth (Kelvin) and so forth. These are shown as "OFF ROAD ONLY" because of the strict limitations they have yet to approve for European use with this whiter color, even though the actual brightness is "technically" about 10% less than their more expensive NIGHT BREAKER LASER version, but about 10% brighter than the Osram's Cool Blue INTENSE. The Cool Blue Intense is about 10% brighter and 10% whiter than BMW's excellent OEM part, which is about 4500K, and better than most OEM lamps for other cars. Having said all this, their is a HUMAN factor to what we perceive that makes the brightness and color ratings offset each other from one bulb to another, and that's where the Cool Blue BOOST excel. A 10% lower lumen rating (brightness) on a 20% whiter bulb (Kelvin) will have the human eye effect of being much brighter, and much clearer, in most cases. Their true Kelvin temperature is about 6500K, and increases maybe 300 after breaking in (20 to 30 hours of use). The human eye can't see this; nor can the human eye see the 10% deficiency of brightness compared to the most powerful Night Breaker Lasers, because they're running at roughly 4500K; and this warmer temperature color (more red spectrum) is part of the increased brightness. But the human eye likes DAYLIGHT brightness, and that is around 5500K at high noon. (Early morning and later afternoon is more like 4000K or lower.) So don't get hung up on "brightness" ratings (Lumen numbers); they're misleading for a number of factors; but there are several real good videos of sales teams testing all these top performers. The HUMAN EYE likes WHITE LIGHT, and the colors on the road at night jump out at you with the Cool Blue BOOST lamps, better than any other. There is some truth to the argument that lower temperature lamps make driving in snow and heavy rain easier to penetrate, because (theoretically) the lower temperature lamps (4200-4800K) don't bounce off particles like brighter white colors do. But that too is human eye perception; and you might like the softer amber shade of lower temperatures. If so, then the best on the block (for now, October 2019) is the Night Breaker Laser. But, if like me, you want a pure white, powerful long range color rich driving experience with a European look for bystanders, then the Cool Blue BOOST is the best choice. The fact that it is "outlawed" abroad makes it even more appealing! WARNING: Watch out for the WAY and WHO you order whatever you get. ONLY buy in FACTORY SEALED PAIRS. It is important with HIDs to get "production lots" matched, and not replacing one bulb at a time, or buying "two packaged" bulbs, where you're getting two SINGLE bulbs. One can be two years on a shelf longer than the other, and have an obvious color shade difference (if that bothers you, as with me). Secondly, RETURN any TWIN BOX that has had the seal broken. The attached photo may not show it, but this seal had been carefully broken and resealed. A buyer in a hurry would open this without noticing it, and maybe wind up with someone else's rejection while paying NEW price. I can't blame the seller or Amazon, but one of my orders was recycled. Lastly, AMAZON has a habit of shipping these GLASS products, well packaged by Osram or not, in an ENVELOPE, which risks even more that the seal will be broken, or worse. So inspect closely before you keep!
