Erinus 1.5W Recessed LED Step Light 80x20 Cool White - White

The Erinus is a recessed LED step light that sits flush within the wall to wash a soft, low-level glow across stairs, treads and floor edges. It draws 1.5W and runs on 12V DC, putting out 30 lumens at a 4000K cool white tone with a Ra 80 colour rendering. Rather than lighting a whole room, this is marker lighting, the small square fitting many US buyers know as a recessed step or stair light, designed to pick out the edge of a step so the route stays clear underfoot without a harsh overhead glare.

Erinus suits indoor staircases, landings, hallway skirting lines and the base of a feature wall, where a run of fittings can mark each tread or guide a path along a corridor. Because it is recessed into the wall, plan for a 12V DC supply behind the surface and space the units evenly so the pools of light overlap gently along the route. Coverage is best judged by throw rather than area: each fitting casts a contained downward spread to graze the step or floor directly below it, so the number you fit depends on the length of the stairway or wall run rather than a square-metre figure. The IP20 rating means it is for dry indoor positions only, so keep it clear of porches, bathrooms and any damp or outdoor location.

Built from plastic with a white finish, the Erinus measures 75 x 16 x 75 mm in a square profile and weighs just 26 g, so it recesses neatly into the wall with minimal disruption. It is a non-dimmable fitting running from a 12V DC supply, with an integrated LED rated for around 30,000 hours of use. The shallow square trim sits close to the wall face for a tidy, near-flush look. This step light is part of the wider Erinus range, which includes further low-voltage marker fittings in matching styles.

Does it need a 12V transformer or driver?

Yes. The Erinus runs on 12V DC, so it needs a suitable low-voltage transformer or driver between the mains supply and the fitting. Size the driver to cover the total wattage of every step light on the circuit, allowing a little headroom.

Can it be used outdoors?

No. This fitting carries an IP20 rating, which means dry indoor use only. Keep it clear of porches, bathrooms, garden walls and any damp or exposed position, and choose a weatherproof fitting for those locations instead.

How is it installed?

It is a recessed mount that sits within the wall, so you will need a recess prepared in the wall surface with the 12V supply run to it. The square trim then sits close to the wall face for a near-flush finish. Its compact 75 x 16 x 75 mm body keeps the cut-out small.

What colour of light does it give?

The Erinus produces a 4000K cool white light with a Ra 80 colour rendering, giving a clean, crisp tone that picks out step edges clearly. It puts out 30 lumens, which suits low-level marker lighting rather than general room illumination.
