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.
