LED DB* Mast Double Luminaire Inclination Adjustment Callisto MC

Back to Overview

Model 368-M DB - Reflector Technology

Product Description and Application

This LED luminaire, being a mast double luminaire, is designed for the illumination of track fields. By flexible assembly options of the mounting fixture versatile applications as top-mounted luminaire are possible.


The inclination adjustment feature of the luminaires allows for sophisticated lighting solutions.


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.


* DB = Deutsche Bahn (German Railways)


Recommended pole height: 6 - 14 metres

The mounting fixture can be equipped variably - so that for each application the optimal lighting solution is found.
