THE BEST: An instant success story, the Osram Cool Blue Intense "CBI" series of HID Lamps has easily out-performed the competitors in all aspects. We're excited to announce that they are now available in a Mercury-free version for vehicles with D4S Headlamps!
AMAZING: What makes them so amazing? Osram's Cool Blue Intense bulbs offer more lumens than the once industry-standard Philips 4300K bulb, 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 D4S bulbs ever made. We've never heard a customer complain that their Osram's weren't worth the money.
GENUINE: Overlitis 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 (even for the new D3S/D4S bulbs!).
