SIG 1227

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)

Areas of application

• Road traffic signalling systems

Safety advice

• Use only in signal equipment/luminaires that are specially designed for the purpose. Protect the lamps against moisture during operation and installation.
