Low-voltage over-pressure lamps for 10 V systems, road traffic
Areas of application
_ Road traffic signalling systems
__
Product benefits
_ Much higher luminous efficacy than high-voltage signal lamps
_ Clearly improved lamp quality due to higher gas pressure and inert gas filling
_ Leads to reduced power consumption of the signal installation
_ High resistance against shock and vibration compared to high-voltage lamps
_ Max. premature failure rate: 2 % up to 4,400 h (related to lamp failures only)
_ Retrofit for 230 V systems (replace lamp and reflector and install transformator)
