24V headlamps are specifically designed to withstand the extreme stress and vibrations to which your trucks and heavy machinery are subjected. Rough roads and vibration are a frequent cause of headlamp failure.
• An increased stiffness of mount and base to provides the ultimate protection against mechanical shock.
• A robust double-coil filament is designed to withstand a wide range of vibration frequencies while remaining stable.
We mount the lamps on a vibration platform simulating the real driving conditions.
We run this platform continuously through all possible vibration frequencies ranging from 80Hz to 1 000Hz.
For vibration frequencies between 80Hz and 150Hz, the lamps encounter up to 13.8 G (gravitational force).
For vibration frequencies between 150Hz and 1000Hz, the lamps encounter up to 6.9 G.
During the test cycle, the lamps are switched on and off with a switching cycle of 10 minutes on and off. The total test time is twenty hours.
