Longlife high-pressure low-voltage lamps for 10V systems, road traffic. Product features: Maintenance intervals of up to one year possible (depending on the system). Product advantages: Increased service life compared to previous low-voltage signal lamps. Max. 2% early failures up to 8,000 hours (only for failures due to lamp faults). Can be replaced with previous low-voltage overpressure lamps without readjustment. Retrofit for 230 V systems (replace lamp and reflector and install transformer). Areas of application: road traffic signal systems.
