LED Ceiling Luminaire Callisto 50

Back to Overview

Model 343-H - 2 LED

Product Description and Application

The LED luminaire Callisto may be used for an appropriate and economical basic illumination of industrial and commercial halls. Bright, high-contrast illumination of production halls and warehouses ensures smooth production processes and safety.
(Additional versions see "Technical Luminaires")


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 155 lm/W at 5,000 K.


Recommended mounting height: 4 - 10 metres


The reflectors can be exchanged within a few seconds by means of a twist-and-lock mechanism. This way, a subsequent adjustment of the light distribution is possible. You find an overview of the light distribution of the different reflector types in the section "Download".
