Best of the Best: Osram's CBI and CBH bulbs are top performers in their category, with an amazing amount of white bright paired with max luminosity; they're topped only by the Osram CBB (Cool Blue Boost) AKA the cream of Osram's crop.
Brightest: In a recent comparison test, the Osram Cool Blue Boost bested the CBH, CBI, and standard by a solid margin. Forget about the fancy names and Kelvin ratings Osram is assigning, these things are simply the best & brightest bulb that Osram currently makes for use in your D2S headlight! (CBB = 460 Lux, CBH = 415 Lux, CBI = 340 Lux, Standard = 315 Lux) Check out our formal review VIDEO!
7000K? So Osram rates these bulbs at 7000K, which is actually quite blue...but in our own testing, we found the CBB to have no more "blue" color to it compared to the CBH (which they rate at 6000K) and/or the CBI (which they rate at 5500K) - in this case, it seems that Osram is actually playing into the common misnomer that Kelvin rating = brightness by rating the bulbs accordingly higher. Weird!
Backed: Bottom line? Though the CBB is new and yet to be tested by the masses, the popularity of their siblings (CBI and CBH) indicates to us that these are going to be extremely popular given the fact that they're considerably brighter, and only marginally more expensive than the alternatives. If you're looking for the best set of D2S headlight bulbs and aren't afraid to spend a few more bucks to get it, look no further, folks.

These are extremely bright and have more intensity than my CBIs. 7k? No. More like 5500k with the smallest hint of blue. The CBIs put at 4800K they are white but are not pure white when on the ground. But if you plan on using d2s 5.0 that have the blue tinted lens they will reduce your kelvins so the CBB with these projectors made them complete pure white with no blue or yellow! Which was exactly since I wanted but in a clear lens projectors they will have a small hint of blue. Definitely worth the money and brighter than CBIs
