Product Details

Dynasty: Year after year Osram is at the top of their game and 2020 is no different thanks to the CBI and CBH bulbs in their arsenal. Thanks to their exceptional lumen count and stunning bright white they're only topped in the lineup by the new king, the Osram CBB(Cool Blue Boost), the pinnacle of their D1S offerings.

Brightest: Let's take a quick look at some data because everything else is just noise. The Osram Cool Blue Boost smoked the CBH, CBI and standard bulbs in testing. Take a look at the hard data. (CBB = 460 Lux, CBH = 415 Lux, CBI = 340 Lux, Standard = 315 Lux) There's no doubt that they're the new king of the mountain.

7000K? With the 7000K rating Osram gives these D1S bulbs, you might call these 'super blue'. In our personal testing, they didn't seem to be much bluer than the already stunning CBH (6000K) so this could possibly be a case of Osram following the misnomer that Kelvin rating = brightness. Be sure to tell us your thoughts when you get these gorgeous lights installed!

Backed:At the end of the day, we know thanks to the popularity of the CBI & CBH lights offered by Osram, that the CBB is going to be a stout performer. We also know it's brighter than anything else available and that if you're looking for the ultimate headlight bulbs for your D1S setup, then this is it.

Genuine: Xenon Depot 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.
