Cool Blue Advanced: Osram's latest introduction to the 6000K bulb market, the Cool Blue Advanced just came out in Q3 2018, and replaces the Cool Blue Hyper bulbs from 2016. If you are looking for the best, brightest 6000K bulb on the market, the CBA is the best of the best for a variety of reasons!

Amazing: What makes them so amazing? Osram's Cool Blue Intense (CBI) bulbs broke all the rules when they produced more lumens than a comparable 4300K bulb while offering a whiter 5500K light output. But now...they've done it again with the Cool Blue Advance. Even more light output compared to the Cool Blue Intense, but in a 6000K version. Mind blown!

Bottom Line: Most people who prefer OEM bulbs these days prefer Osram. Most people who prefer Osram prefer the CBI. Most people preferred the CBI because it was the brightest...so we have a feeling these will pick up in popularity pretty quick! No matter the preference, we have your Osram HID replacement bulbs!

In Testing: Powered from the same Matsushita ballast and projected through a new Morimoto 4TL-R Bi-xenon projector, the CBH trumped all. We'll let the numbers do the talking. Philips 85122 WX: 223 Lux. Osram D2S CBI: 316 Lux. Osram D2S CBA: 332 Lux!

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.

Awesome bulbs 6000K color hue correct as described, I highly recommend these OSRAM 66240 CBH over the Philips 85122 WX 6000k that has a more reddish color hue. I would also buy a second pair for my Audi A3.


Osram 66240 CBH


I purchased a set of the cool blue Hyper bulbs from TRS and I have got to say they are completely spot on that this is the best of the best. The color is amazing. The road in front of the car is bright white and the road signs illuminate perfectly. They are definitely worth the money, you will not be disappointed. Keep up the great work TRS!!!!!!!!!




As advertised and bright... clean white with a small blue hue. Couldn't be happier.
