The LMXE DLO (Directional Linear Optics) Intelligent Emergency range is ATEX, IECEx and UKEX certified for safe use in Zone 1,2 and 21,22 potentially explosive atmospheres. It has all the features of the LMX DLO Linear standard luminaire, with the additional safety of a battery powered emergency back-up supply should power fail in the Hazardous Area.

The LMXE DLO Intelligent Emergency is available in the 2 different standard industry sizes

Product Information

ZONES: 1, 2, 21 AND 22

The LMXE DLO (Directional Linear Optics) Emergency has all the features and benefits of the standard LMX linear range (see standard linear models), with the additional advantage of the following emergency mode durations (selectable by the installer on-site) supplied by the NiMH battery:

You can choose from the following options:

• 4 hours at 25% output (LMX2E models); 4 hours at 12.5% output (LMX4E models)
• 2 hours at 50% output (LMX2E models); 2 hours at 25% output (LMX4E models)
• 1 hour at 100% output (LMX2E models); 1 hour at 50% output (LMX4E models)

LMX4E DLO models have one “emergency” and one “standard module”

The Intelligent Emergency circuit automatically performs periodic functional and battery duration self-testing to monitor the system and battery condition. Throughout this period LED output from the Emergency Linear remains at full power to ensure activities and operations in the vicinity remain undisturbed.

A 3 colour LED indicator will show the state of the circuit:
• Green indicates that everything is functioning correctly
• Amber indicates the unit is executing a self-test
• Red indicates a fault or that the battery hasn’t reached full capacity
(see manual for further details)


  • All the features of the standard LMX DLO linear range

    Additional advantage of 3 selectable emergency mode durations

  • Fully Retrofitable

    Easy to convert existing fluorescent lamps to high power low energy consumption LEDs

  • Fitted with patented and revolutionary Directional Linear Optics (DLO)

    For unique directional, low glare, human centric lighting
