This 25W mercury-free Xenon lamp doesn’t require a lens cleaning system in Europe, which saves cost, volume for the water tank, and 3 to 4 kg of weight per vehicle. The headlight system has a reduced wattage of 25W compared to 65W for halogen headlamps, reducing CO2 emissions by around 2 g / km.Moreover, the Xenon 25W lamp gives about 50% more light than halogen and a higher colour temperature of 4500K.
Here is a comparison of halogen, Xenon 35W and Xenon 25W light sources:
|Nominal power of the bulb with electronics
|Real power on the car at 13.2V
|Average of the real power of the car (nighttime/daytime, around 33%)
|Lifespan B3 at 14V
|Total weight of the light bulb system
According to what has been presented to DVN, the optical surfaces of the projector module for this Xenon 25 W lamp have been completely redesigned to give an extremely homogeneous illumination of the road. Added to the increased light output of low and high beams a superior driving safety is achieved at night.
As the total system costs are lower compared to a 35W BiXenon system, we can expect in the near future a great extension of this type of system to small and medium cars. Ford also want to present to their “green”
