Ontec S 3.3W Maintained Self-Test Emergency Light IP65 Surface - White

The Ontec S is a surface-mounted emergency led light delivering 3.3W and 150 lumens at a crisp 5000K daylight tone, designed to mark escape routes clearly when mains power fails. Running on 220 to 240V AC, it operates as a maintained fitting, so the light stays on during normal use and switches to its internal battery the moment supply is lost. This compact format is what specifiers in the US would recognise as an emergency exit luminaire, sitting flush against a wall or ceiling rather than recessing into it.

Its job is route marking rather than general illumination, so coverage is best judged by how plainly it picks out a corridor, stairwell or doorway in darkness rather than by any room area figure. The IP65 rating opens up a wide span of locations, from internal circulation spaces through to exposed outdoor walkways, loading bays, covered car parks and damp utility areas where splashing or weather is a factor. Surface mounting suits sites where chasing into the structure is not practical, and the daylight 5000K output reads quickly under stress conditions on both wall and ceiling positions.

Built from white plastic and weighing 518g, the Ontec S carries an IP65 rating that keeps water and dust out in wet and dust-laden settings. The self-test function runs its own duration and function checks automatically, easing the regular testing routine required for emergency installations and flagging faults without manual intervention. Mounting is by surface fixing to wall or ceiling, and the clean white housing keeps it discreet. The wider Ontec range includes further wattage and mounting variants for matching across a building.

Is this a maintained or non-maintained emergency light?

The Ontec S is a maintained fitting, which means the light is illuminated during normal mains operation and continues to run on its internal battery if the supply fails. This makes it well suited to areas that need constant lighting as well as guaranteed cover during a power cut, such as public corridors and exit routes.

Can it be used outdoors or in wet locations?

Yes. With an IP65 rating it is fully weatherproof and protected against dust and water jets, so it is suitable for exposed outdoor walkways, covered car parks and damp utility areas. It performs equally well in standard internal escape routes.

What does the self-test function do?

The Ontec S runs automatic function and duration tests on its own, checking the battery and lamp without anyone having to manually trigger them. This reduces the routine maintenance burden on emergency installations and helps flag a fault before it becomes a compliance issue.

How do I clean and maintain the fitting?

Wipe the white plastic housing with a soft, dry or slightly damp cloth, avoiding solvents that could mark the surface. Keep the lens clear so the 150 lumen output stays unobstructed, and let the built-in self-test handle the functional checks alongside your scheduled inspections.
