LED DB* Platform Luminaire as Mast Luminaire Callisto 50

Back to Overview

Model 335-M - Reflector Technology

Product Description and Application

This LED luminaire has been designed as mast luminaire for the illumination of railway platforms. Having the choice between different adapters the luminaire can also be installed as double luminaire, either without inclination adjustment or, for higher requirements, with inclination adjustment.


Pay attention to the quality and efficacy of the product. Having an optimised luminous intensity distribution, the quantity of luminaires can be reduced due to larger luminaire spacing. The luminaires are equipped with highly efficient LED modules - supplying nominally 99 lm/W at 4,000 K.
