DB* LED Escape Sign Luminaire RZL Mod. 934
Back to OverviewModel 934 - 24 V
Product Description and Application
The DB* LED escape sign luminaire has been particularly designed for applications within the Deutsche Bahn (German Railways) and it is suited for the illumination of escape routes inside tunnels. The luminaire can be used flexibly:
1. Simply as escape sign luminaire with blue pictogram
2. As escape sign luminaire in conjunction with illumination of the escape route
The luminaire passed the pressure and dynamic pressure tests of the DEUTSCHES ZENTRUM FÜR LUFT- UND RAUMFAHRT (German Aerospace Centre).
The luminaires are equipped with highly efficient LED modules - supplying nominally 99 lm/W at 4,000 K.
* DB = Deutsche Bahn (German Railways)
Recommended mounting height: 2 - 3 metres
