The Best: Easily the best D1S bulbs to ever hit the market, we are honored to offer the ultimate Osram CBI Bulbs. Indeed they are the “Rolls Royce” of D1S Lamps.  HID BULBS

Amazing: What makes them so amazing? Osram’s Cool Blue Intense bulbs offer more lumens than the once industry-standard Philips lamp, but with a higher Kelvin rating of 5000K. Whereas most bulbs lose lumens when their Kelvin rises, the CBI’s still manage to give users the benefit of brighter light combined with whiter light – the best of both worlds indeed!

Backed: Bottom line? Everybody who uses them agrees they’re among the best D1S bulbs ever made. We’ve never heard a customer complain that their Osram’s weren’t worth the money.

Genuine: Retrofit Wholesale 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.
