These are 20% brighter than the factory OEM bulbs that come on your vehicle from the manufacturer. The bulbs are plug and play and extremely easy to install and replace your factory HID bulbs. Easily the best D1S bulbs to ever hit the market, it's no wonder auto makers such as Mercedes and BMW are starting to spec the D1S CBI in their flagships such as the new F10 5 series and S65. Indeed they are the "Rolls Royce" of D1S Lamps.
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 up to 6000K.
So what? Meaning they are physically brighter and offer more contrast at night, which makes them seem even brighter than they already are. In summary, everybody who uses them agrees they're the best D1S bulbs ever made.
Don't just take our word for it, read the reviews on HID planet!
We recommend professional installation especially with D1S bulbs, as their multi-pin connector is highly sensitive if installed improperly.
The K5 Optima Store & the Retrofit Source 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.
