R. Stahl’s line of light fittings for use in Ex zone 1/21 and 2/22 hazardous areas achieves better energy efficiency than comparable devices and provides approximately 10 % more luminous flux. Exlux 6001 luminaires also feature a design that is considerably more compact, stable, and torsion-resistant than their Exlux 6000 predecessors. Depending on their performance class, the 6001 luminaires are a quarter to a third lighter than their predecessor models. Users now also benefit from the robust design of these slimmer, narrower units: unlike most lights, the devices can be operated at extremely low ambient temperatures (as low as -30 °C). In order to facilitate a step-by-step exchange of existing Exlux pendants, the installation of the new units remains fully compatible to the predecessor series.
