ATEX Certification IECEX Certification CE0598 Certification

Zones: 1, 2, 21 and 22


The LinkEx™ LED Temporary Luminaire is a high powered LED leadlamp for use in short-term lighting installations and maintenance tasks and is CE marked to the ATEX Directive and IECEx Certified for safe use in Zones 1 and 2 potentially explosive gas and dust atmospheres, where a T3/T4 (model dependent) temperature class permits.

The new T4 model:

  • Has 25% more light output at source
  • Has 300% the light output at the widest part of the beam - 33 lux at 2 metres
  • Weighs almost 20% less

The range of LinkEx™ LED Temporary Luminaires provides high quality ambient lighting.  Each light utilises two arrays of high power LEDs which:

  • Supply brilliant white light output
  • Are highly reliable
  • Are a low maintenance 'fitted for life' light source, and allow power savings which allow longer cable runs and more lights to be powered from a single supply

Luminaires are available in '180°' format (arrays side-by-side) to give effective unidirectional illumination or in '360°' format (arrays back-to-back), to special order, to give effective omni-directional 'all round' illumination.

The unit’s construction is lightweight, compact and highly robust, with impact resistant end caps and tube (with anti-static and light diffusing coatings) plus the high visibility shock absorbing bump rings are chemical resistant and minimise the risk of drop damage, all ideal for handling in demanding conditions. Units can be fitted with integral ATEX sockets allowing multiple lamps to be quickly and safely connected and positioned in a chain, even whilst energised in an Ex Atmosphere.

Available in two voltage input ranges: high voltage 90-264V AC for general applications and low voltage 18-50V AC/DC for use in confined space applications, such as metal tanks, with a higher risk of electric shock. The wide input voltage ranges maximise usability and safety for chains of multiple lights or for long cable runs, where supply voltage can drop. The unique SOVI™ (Safe Optimal Voltage Indicator) monitoring system clearly indicates when the supply voltage is operating outside the specified limits;  in the LV versions and the T4 HV models, the light will pulse either dimmer (if voltage input is above the specified limit) or pulse brighter (if the input voltage is below the specified limit).  In the T3 HV versions an LED indicator will flash to alert the user to take appropriate action.
