DB* LED Luminaire PaLeStra® B
Back to OverviewModel 883
Product Description and Application
Based on the excellent concept of the "big" PaLeStra® this smaller patented version is characterised by its compact design and its low wattages. The PaLeStra® B in particular serves for glare-free applications.
The PaLeStra® B is particularly suitable for track field lighting and the illumination of railway crossings.
The luminaire passed the pressure and dynamic pressure tests of the DEUTSCHES ZENTRUM FÜR LUFT- UND RAUMFAHRT (German Aerospace Centre).
In addition to the excellent energy efficiency, a service life of more than 100,000 hours and minimal maintenance work provide further saving potentials.The luminaires are equipped with highly efficient LED modules with nominally 99 lm/W at 4,000 K.
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.
