LX-400EH/T4/SY10/ATX110, LX-400EHA110/T4/SY5, LX-400EH/T4/SY10/ATX230, LX-400EHA230/T4/SY5, LX-400ELA24/T4/SY5, LX-400EL/T4/SY10/ATX24

ATEX Certification IECEX Certification CE0598 Certification

Zones: 1, 2, 21 and 22

The LinkEx™ LED Temporary Emergency Luminaire has all the product features of the existing LX-400 range of LED Temporary Luminaires - including the unique SOVI™ (Safe Optimal Voltage Indicator) system - and in addition provides increased safety by automatically switching to the battery power source should there be any interruption to the normal power supply.

Running on the built-in battery supply, light will be emitted at a  reduced level for 3 hours, allowing  safe evacuation of the Hazardous Area.

The new LinkEx™ LED Temporary Emergency Luminaire 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 T4 temperature class permits.

Giving high quality ambient lighting, each unit utilises two arrays of high powered LEDs to give a brilliant white light output, high reliability and a low maintenance, 'fitted for life', light source.   The luminaires will be supplied in a '180°' format with the LED arrays positioned  side-by-side to give effective unidirectional illumination.

Lightweight, compact and robust, the luminaire has impact resistant end caps and tube (with anti-static and light diffusing coatings).

High visibility, chemical resistant, shock absorbing bump rings minimise the risk of drop damage. An ATEX socket can be fitted to allow multiple lamps to be quickly and safely connected and positioned in a chain whilst energised. 

Available in HV 90-264V AC/DC and LV 18-55V 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 - the light will pulse dimmer if the supply voltage is above the specified limit, and brighter if below the specified limit.

Available in an Emergency Exit version, the luminaire positioned at exits, doors, escape routes, stairways and intersections ensure safe evacuation if needed.
