With its Ultra White bulb range, Bosch offers an attractive halogen bulb with optical benefits similar to xenon bulbs. A particular advantage of xenon headlights is their similarity to daylight. However, their high price means that they are mainly installed in premium vehicles. With a colour temperature that has now been improved to a range between 4,200 and 4,800 Kelvin, depending on headlight type, the Ultra White bulb range emits an especially intensive white light that comes close to daylight with 5,500 Kelvin. When driving at night, the light is more soothing for the eyes and causes less fatigue due to higher contrast. Emitting up to 40% more light, these intensively white bulbs also offer better vision than standard halogen bulbs – not only in the dark, but also in difficult weather conditions such as rain and fog.
