The LinkEx™ Portable Fluorescent Leadlamp is suitable for a multitude of applications where a temporary light is required for extended periods of time and is CE marked to the ATEX Directive and IECEx Certified for safe use in Zones 1 and 2 potentially explosive gas, vapour, mist and dust atmospheres, where a T3/T4 temperature class permits.

Available with twin side by side forward facing, or quad back to back energy efficient fluorescent lamp combinations in a wide range of voltages (24V – 254V). The leadlamps can be supplied with direct cable entries or fitted with ATX plugs/sockets to allow the units to be instantly linked in series (plug and play), allowing for quick and easy installation over a large area. Rugged construction, and compact design allow lights to be connected together in the explosive atmosphere while energised.  

Unistrut compatible mounting points on the lamps provide a flexible installation solution allowing them to be quickly and easily fixed in position on pipes, scaffold or a ferrous backdrop with magnetic fixings. Accessories are available to provide a quick, easy and low cost solution for mounting the lamps.  

Easy maintenance is a key feature of the LinkEx™ Portable Fluorescent Leadlamp, re-lamping is simple and quick using standard compact fluorescent lamps readily available from electrical retailers and the operation takes a few minutes and can be done by a competent electrical engineer.   The leadlamp is also certified to the ‘End of Life’ protection circuit ballast for enhanced safety, in accordance with HSE safety notice 8/05.
