The Best: Easily the best D2S bulbs to ever hit the market, we are honored to offer the ultimate Osram CBI Bulbs. Indeed they are the "Rolls Royce" of D2S Lamps. Amazing: What makes them so amazing? Osram's Cool Blue Intense bulbs offer more lumens than the once industry-standard Philips 85122+ 4300K bulb, but with a higher Kelvin rating of 5500K. 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 D2S bulbs ever made. We've never heard a customer complain that their Osram's weren't worth the money.Feedback: Don't just take our word for it, read the reviews on HIDplanet Genuine: Here at Wise Detailz, we pride ourselves on being one of the last few distributors shipping genuine Philips & Osram lamps in the US.
