Osram D1S: Osram 66140 XNN (4200K) (Duobox)
The King: It wasn't long ago that the XV2 from Philips was the brightest bulb on the market. No More! Osram's all-new Night Breaker Laser has taken the rank and recently tested to be the BRIGHTEST HID bulb currently on the market. "Laser": What makes them so amazing? The old Osram XNB (standard Night Breaker) was touted to have "Up to 70% more light output" compared to a standard bulb. The XNL Laser? 200%! Thanks to the most modern technology and some crafty physical changes Osram made to the focal position of the bulbs, they've really pulled out the stops on low beam performance! Audience: So, you're considering a fresh set of bulbs, are you? Well, if you A) don't mind the price, B) wasn't the brightest possible option, and C) don't really care much about cooler color temps in the 5-6000K range, then these are right for you. Put differently: They are for the dude who's serious about driving in all-weather conditions, doesn't give a shit about looking "cool", and only buys the best parts for their car. Backed: Bottom line? We've always been Osram fan boys here; They've continued to up the performance from their product line every year, and as annoying as it is to continually update the catalog, we're blown away by the bump in output every time. Our hats are also off to Osram for maintaining focus on improving HID bulb tech even though it's technically "old news" by today's OEM standards. HID is King, and Osram is the King of HID. We're 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.
