Energy-saving lights for hazardous areas: Compact LED design

Published: 2 February 2015 - Marianne Evans

R. STAHL now offers 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 merely 55 mm, the new lights take up less than half the space required by conventional linear luminaires, and reach less than half their weight.

What is most striking, however, is the design that makes the new 6036 series extraordinarily light-efficient: 30 four-foot long LED-based tubular light fittings, for instance, ensure an illuminance of approximately 500 lx, which would usually require 35 linear luminaires with two 36 W fluorescent tubes each – or alternatively 48 conventional box-type units retrofitted with LEDs. However, R. STAHL’s new lights consume only about half as much power and the specific power consumption per 100 lx is merely 1.5 W/m². This ensures enormous savings regarding operating costs – depending on the comparative solution and the time frame, 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 excellent suitability for maritime applications. In addition to ATEX and IECEx certificates, they also feature certificates for many major markets (GOST, Gazpromnadzor, UL do Brasil, GL).
