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 D1S headlight bulbs and aren't afraid to spend a few more bucks to get it, look no further, folks.
