ONTEC S 3.3W Maintained Emergency Light Auto-Test Surface IP65 - White

The ONTEC S is a surface-mounted emergency light fitting running 3.3W from a 220-240V AC mains supply, with an integrated battery that takes over the moment the power fails. It puts out 150 lumens of crisp 5000K light, the cool daylight tone specified for escape routes so signage and obstacles read clearly under low-level emergency conditions. North American specifiers will recognise this format as a surface emergency luminaire; the maintained build means the LED can stay lit during normal use and continue on battery when mains is lost. An auto-test function cycles the unit on a set schedule, logging its own function and duration checks without a manual walk-round.

The ONTEC S is built for corridors, stairwells, plant rooms and the exit points of commercial and industrial buildings where a clear escape path has to be lit if the supply drops. Rather than lighting a room to a working level, it marks the route, throwing enough light along a corridor or over a doorway to guide people out safely, which is the job an emergency fitting is rated to do. The IP65 weatherproof rating extends that to exposed external routes, covered car parks, loading bays and damp utility areas, so it suits both sheltered interiors and fully outdoor positions. It mounts to a wall or ceiling, letting you place it above an exit or along the line of travel.

Construction is a white plastic housing weighing 456g, sealed to IP65 against dust and water jets for reliable service in wet and dusty settings. The maintained driver and integral battery sit within the body, so there is no separate gear to specify, and the auto-test electronics handle scheduled function checks on their own. The crisp white finish keeps the unit discreet against most ceilings and walls. Our wider Ontec emergency range covers further wattages and switching options to match a building's escape-lighting scheme.

Is this a maintained or non-maintained emergency light?

The ONTEC S is a maintained fitting, so the LED can be lit during normal operation and stays on automatically if the mains supply fails. This makes it well suited to spaces that need both general presence lighting and emergency cover from a single unit.

What does the auto-test function do?

The auto-test electronics run the fitting through its own scheduled function and duration checks, confirming the battery and LED operate correctly under emergency conditions. This removes the need for routine manual testing and keeps a building's escape lighting verified between inspections.

Can the ONTEC S be used outdoors?

Yes. With an IP65 rating it is sealed against dust and water jets, so it is suitable for exposed outdoor routes, covered car parks, loading bays and damp utility areas as well as sheltered interiors.

How long does the emergency light run on battery?

The integral battery powers the 150 lumen output once the mains supply is lost, holding the escape route lit for the rated emergency duration. Confirm the exact backup time against your scheme's requirement, as escape lighting is typically specified to run for a set minimum period.
