R. Stahl has released compact LED-based tubular light fittings for use in Ex zones 1/21 and 2/22 that provide users with an alternative to typical linear luminaires.
With a diameter of 55mm, the new lights take up less than half the space required by conventional linear luminaires, and reach less than half their weight.
The 10m long LED-based tubular light fittings provide an illuminance of approximately 500lx, which would usually require 35 linear luminaires with two 36 W fluorescent tubes each – or alternatively 48 conventional box-type units retrofitted with LEDs.
The new lights consume only about half as much power and the specific power consumption per 100 lx is 1.5 W/m². This ensures enormous savings regarding operating costs – depending on the comparative solution and the timeframe, just under 20% to more than 50% savings are realistic in practice.
The tubular light fittings can be operated in a very wide temperature range from -40 to +60 °C. The maintenance-free units are suitable for general lighting purposes or for use as machine lamps.
Due to their slim design, they can be installed in hard-to-access locations. Even at an ambient temperature of +60 °C, they reach a lifetime of 80,000 hours. The vibration-proof units are IP66/IP67-protected by default, resulting in suitability for maritime applications.
