-Max. premature failure rate: 2% up to 4400h (related to lamp failures only)
-Retrofit for 230V systems (replace lamp and reflector and install transformator)
Areas of application
-Road traffic signalling systems
Safety advice
Use only in equipment/luminaires that are specially designed for the purpose.
Protect the lamps against moisture during operation and installation.
