The LinkEx™ LED Temporary Luminaire series delivers powerful, efficient, and reliable illumination designed specifically for use in hazardous environments, including Zones 1, 2, 21, and 22. Engineered for safety and durability, these luminaires are ATEX and IECEx certified for use in explosive gas and dust atmospheres, with a T4 temperature class rating and maximum surface temperature of 135°C. Designed with rugged field conditions in mind, the luminaires feature impact-resistant polycarbonate housings with anti-static, light-diffusing coatings, and high-visibility chemical-resistant bump rings that provide shock absorption and help protect against drop damage. These design choices make them highly suitable for demanding industrial applications where reliability and safety are critical.
Each unit incorporates two high-power LED arrays that provide brilliant, wide-angle white light either in a 180° configuration for focused directional lighting or, by special order, in a 360° back-to-back configuration for full omni-directional illumination. With a source output of up to 4,000 lumens, these fixtures deliver high light intensity at the widest part of the beam and offer consistent, energy-efficient performance with over 60,000 hours of operational life. The LED light source is classified as "fitted for life," ensuring minimal maintenance needs and long-term cost savings.
A key safety innovation in the LinkEx™ luminaires is the built-in SOVI™ (Safe Optimal Voltage Indicator) system. This feature monitors incoming power and alerts users when the supply voltage is outside the recommended range. When the voltage is too high, the light pulses dimmer; when too low, it pulses brighter—helping maintain optimal performance and operational safety. The system supports operation down to 0 volts, enhancing protection against voltage irregularities in hazardous zones.
These temporary luminaires are available in both high voltage (90–264V AC) and low voltage (18–50V AC/DC) versions, making them suitable for a wide range of environments, including confined spaces like metal tanks where the risk of electric shock is higher. The wide input voltage compatibility ensures performance stability across long cable runs or installations with multiple luminaires in series. Select models are equipped with integral ATEX plugs and sockets, allowing quick and safe connection of multiple units in a live hazardous atmosphere without de-energizing the system.
All variants support a compact, lightweight design, weighing approximately 3.0 kg (excluding cable) and measuring 0.7 meters in length for non-linkable versions. The ingress protection rating varies by configuration: IP67 for non-linkable units and IP66 for those with sockets for linkability. The luminaires utilize a wide-angle, diffused area beam type and operate at a typical power consumption of 26–27 watts depending on the voltage. The certification references include CML 18ATEX3371X and IECEx CML 18.0197X, with Ex classifications such as II 2 GD Ex eb mb IIC T4 Gb (-20°C to +55°C) and Ex tb IIIC T135°C Db, confirming compliance with stringent safety standards.
Overall, the LinkEx™ LED Temporary Luminaire line is a high-performance, safety-forward lighting solution for hazardous environments, offering outstanding illumination, low maintenance, excellent durability, and flexible installation options for industrial users.
