Low-voltage over-pressure longlife lamps for 10 V systems, road traffic. Product features: Maintenance intervals up to one year possible (depending on installation). Product benefits: Increased lamp life compared to existing low-voltage signal lamps. Max. premature failure rate: 2 % up to 8,000 h (related to lamp failures only). Exchange of existing low-voltage high-pressure lamps possible without adjustment. Retrofit for 230 V systems (replace lamp and reflector and install transformator). Areas of application: Road traffic signalling systems.
