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!
