Product datasheet SIG 1227 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) May 25, 2016, 17:21:50 SIG 1227 © 2016, OSRAM GmbH.
