Description
The APUS is a compact recessed LED step light that sits flush within the wall to mark stairs, landings and low-level routes. It draws just 0.8W from a 12V DC supply and puts out 13 lumens at a warm 3000K colour temperature, giving a soft pool of light at floor level rather than broad illumination. American buyers searching for a low-voltage step light will find the same low-level marking format here, in a small 75 mm square footprint. The warm white tone keeps the effect gentle underfoot, with a Ra 80 colour rendering that reads finishes and tread edges accurately.
This fitting suits indoor staircases, hallway skirting runs and the base of internal walls where a quiet guiding light is wanted at night. Because it is a low-level marker rather than ambient room lighting, the output is best judged by what it picks out: each unit washes the immediate tread or floor area beside it, so a flight of stairs is typically lit with one APUS every few steps rather than a single fitting. It is rated IP20 for dry indoor use only, so keep it clear of bathrooms, porches and any outdoor or damp location. Plan the recessed positions during first fix so the wiring and back box can be set into the wall before finishing.
The APUS combines a polished stainless steel face with a plastic body and recesses into the wall via a back box rather than surface mounting. It runs on 12V DC, so it needs a suitable low-voltage transformer or driver feeding the circuit, and it is not dimmable. The square 75 × 23 × 75 mm body weighs just 84 g and is finished in black to recede against darker walls and treads. Rated for 50,000 hours, it is built to run for years with little attention. The APUS sits within a wider range of low-level Apus markers in matching styles.

Frequently Asked
Does the APUS need a 12V transformer or driver?
Yes. The APUS runs on 12V DC, so it must be fed from a suitable low-voltage transformer or LED driver rather than wired straight to mains. Size the driver to the total load of all the step lights on the circuit, allowing for the 0.8W draw of each unit.
Can the APUS be used outdoors or in a bathroom?
No. The APUS is rated IP20, which means it is for dry indoor use only. Keep it clear of bathrooms, porches, garden walls and any damp or outdoor location, and choose a weatherproof fitting for those areas instead.
How is the APUS installed?
It is a recessed mount fitting that sits flush within the wall using a back box, not a surface-mounted unit. Set the back box and 12V wiring into the wall during first fix, before plastering or final finishing, so the polished face sits clean against the surface.
What colour of light does it give?
The APUS produces a warm white 3000K glow with Ra 80 colour rendering, giving a soft, low-level light at floor level. The warm tone keeps stair edges and skirting gently lit at night without a harsh or clinical feel.
