DDM Tuning Ultra HID Bulbs, OEM Quality, 20% Brighter, 9006 / HB4 6500K Pair Modeled after the Osram CBI line of performance bulbs we've sourced quartz glass from Philips, salts from APL USA and electrodes from Plansee in Austria. On top of this we've redesigned the capsule to produce up to 20% more light than the standard Apexcone HID bulbs which are already an industry leading bulb. The quartz glass is optically clear with a UV coating to protect the headlights from UV radiation. The warm up time on the Ultra bulbs is 20% quicker than Apexcone bulbs and will reach full brightness in 10-15 seconds. Manufactured in a state of the art facility using automated processes we guarantee perfect alignment of the xenon capsule for the best beam pattern possible. With utput up to 3400 Lumens when used on a 35W ballast and 5000 Lumens on a 55W ballast you're sure to be seen. Premium Ultra HID Bulbs come with a 1 year warranty.
