Brighter bulbs are designed for better downroad and sideroad performance.
SYLVANIA defines clarity as the combination of downroad, sideroad, and white light. Increased clarity is acheived from brighter downroad, greater sideroad, and whiter light, and can improve contrast and object visibility such as street signs and road hazards.
Whiter light can improve contrast and object visibility such as street signs and road hazards. It can also help with peripheral visilibity. More information on the study of headlights can be found here. These are reports created by the Light Research Center at Rensselaer Polytechnic Institute.
OSRAM Sylvania performs extensive laboratory testing on all the bulb types we manufacture. The bulbs are tested in a controlled environment to SAE and USCAR testing standards. Rated life is the expected minimum average life as determined by large scale lab testing over long production periods. Individual lifetimes may vary based on application, ambient conditions, vehicle voltage, and vehicle usage.
An average driver will use their low beam headlights 100 hours per year. The value can be found here, a report created by University of Michigan Transportation Research Institute.
