The new generation of R. STAHL's LED-based tubular light fittings for use in hazardous areas (Ex zones 1, 2, 21 and 22) combine excellent energy efficiency with great usability and easy handling. These very compact tubular, machine and inspection lights (6036, 6039 and 6149/2 series, respectively) are low-maintenance products with a very long service life even in extremely harsh environments, including marine applications. Fully living up to R. STAHL's "Ex 4.0" concept, they feature a variety of regional and sectoral certifications that facilitate almost universal use throughout the world. The luminaires provide IP68 ingress protection, are shock-proof and vibration-proof and withstand even extreme ambient temperatures that range from -55 °C to +70 °C, with exact specifications depending on the model.
Due to their slim, lightweight design, 6036 and 6039 series lights for general lighting purposes or for use as machine lights can be easily installed even in hard-to-access locations. Compared to conventional linear luminaires, superior illuminance is ensured by these very efficient high-performance LEDs: 30 four-foot 6036 series LED-based tubular light fittings provide approximately 500 lx, enough to replace 35 linear luminaires fitted with two 36 W fluorescent tubes each, or 48 conventional box-type units retrofitted with LEDs. The total power consumption of the LED tubular lights is only about half as high, and the specific power per 100 lx is only 1.5 W/m². 6039 series machine lights weigh less than 1.5 kg and provide a very uniformly illuminated working area due to a wide beam angle of ±60°. They consume less than 15 W of power and achieve a luminous flux of 1,000 lm. The flicker-free LED light provides enhanced safety especially near rotating equipment. Glare is reduced by a diffuser. Type 6149/2 inspection lights complete R. STAHL's user-friendly portfolio of compact lamps. These robust, very lightweight portable lamps also feature excellent lighting characteristics with a luminous flux of 600 lm and a wide, low-glare beam angle. They are available with different rated voltages and an optional wire guard. The lightweight products' real-life durability in rough environments is also captured on video by the "R. STAHL Explorers", whose website www.stahl-explorers.com also presents background information on LED technology and news about lighting solutions.
