Mercedes-Benz makes xenon light even brighter with OSRAM

Starting with the E and S class from December 2010

(PresseBox) (Munich, ) Daylight-like colour temperature is one of the greatest safety benefits of headlamp technology. Mercedes-Benz is now the first carmaker to offer a significantly brighter light with xenon headlamps.

Since December, new xenon bulbs by OSRAM have been included in the production of E and S class vehicles, whose colour temperature has been increased by 20 per cent. At 5,000 Kelvin the new xenon light is even closer to daylight and therefore shines even brighter - a visual innovation in the truest sense of the word.

OSRAM's new D1S CBI is unique to the extent that no other manufacturer has succeeded before in producing a 5,000-Kelvin lamp in OEM quality. It now offers the best possible performance combined with the best possible quality. Previous models mainly used coatings on the outer bulb, which resulted in significantly reduced light output and failed to spread the light evenly on the road.

The new colour temperature caters to human ways of seeing things; it gives the eye an impression of increased brightness and is therefore a relief for drivers. Tests show that artificial light strains the eye less the closer its temperature is to daylight. This is a crucial increase in safety considering only 20 per cent of driving is done at night - but that is when 40 per cent of fatal accidents occur.

Following the E and S class models, other Mercedes-Benz series will be gradually equipped with the new xenon bulbs during 2011. In addition, all previous Mercedes-Benz vehicles with xenon headlamps can have this safety upgrade done. The new xenon bulbs will be available as Mercedes-Benz original parts at its locations and dealerships as well as retail outlets in versions D1/D2.
