The same shock resistance of MasterDuty combined with new technology to extend the life (1800 hours).
New, more durable gas-filling composition designed to reduce tungsten evaporation.
minimal downtime: save downtime associated with replacing bulbs!
high-performance quartz glass to withstand temperature and pressure.
Increased rigidity and mounting base to provide ultimate protection against mechanical impacts
robust double coil filament designed to withstand a wide range of vibration frequencies while maintaining stability
high-performance quartz glass to withstand temperature and pressure. Bulbs are designed tvibration and excellent durability. These bulbs last twice as long and twice as resistant to vibration than average bulbs on the market. Many MasterDuty Longer Life has a rigid mounting base and better protects against mechanical shock. Moreover, it has also robust fiber with double winding, that can withstand intense vibration and retains stability. Many MasterDuty is the right choice for drivers requiring rigidity and durability.
