A hallway or staircase asks a wall lamp to do something a bedside light never has to: stay clear of shoulders, bags and people passing in both directions. This guide looks at four Louis Poulsen wall lamps through the three questions that decide the choice in narrow spaces: how far each one stands off the wall, where it should sit on a stair, and whether a corded or hardwired version makes more sense.
Start with projection, not diameter
In a corridor the figure that matters most is depth, the distance a lamp projects from the wall. Width shapes how a lamp looks; depth decides whether someone carrying a basket brushes against it. Among these four designs the spread is wide, from 60 mm on the smallest Flindt to 290 mm on the VL 38, and that alone rules some of them in or out.
| Design | Designer and year | Size (mm) | Weight | Light source | Best for |
|---|---|---|---|---|---|
| Flindt Wall Lamp Ø 200 | Christian Flindt, from his 2017 bollard | 200 x 60 deep x 200 | 2.1 kg | Built-in LED, 10 W, 2700 K or 3000 K, IP65 | The narrowest corridors, entrances inside and out |
| AJ Eklipta Wall Lamp Ø 220 | Arne Jacobsen, 1956 | 220 wide x 105 deep | 1.0–1.4 kg | G9, max 33 W, or integrated LED, IP20 | A calm row of light along a passage |
| PH Hat Wall Lamp | Poul Henningsen, 1961 | 225 x 225 x 153 | 1.8 kg corded, 3.5–3.9 kg hardwired | E14, max 20 W, IP20 | Stairs and landings where glare matters |
| VL 38 Wall Lamp | Vilhelm Lauritzen, late 1930s, relaunched 2016 | 135 x 190 x 290 | 2.4 kg | Built-in LED, 9.6 W, 2700 K | Wider halls, landings and a console by the door |
Before choosing, tape a piece of card cut to the lamp's depth to the wall and walk the corridor at normal pace. If you turn your shoulder, the lamp is too deep for that spot.
The shallow options: Flindt and AJ Eklipta
Flindt Wall Lamp
The Flindt Wall Lamp in Ø 200 is the slimmest design here at 60 mm deep. Christian Flindt carried the carved ellipse of his 2017 bollard onto a die-cast aluminium disc that appears to float slightly off the wall. The light comes from a recessed crescent and falls downward as an asymmetrical, glare-free wash, with a faint ring of reflected light across the lamp's own face. In a passage that means light on the floor, nothing bright at eye level.
Two practical points. It is rated IP65, so the same model can mark the front door outside and continue into the hall inside. And it is made for fixed installation by a certified electrician, so it suits a renovation. Finishes are black, white, aluminium colour and corten colour, all textured. For a tall stairwell, the Ø 300 (80 mm deep) and Ø 400 (100 mm deep) give more presence without adding much projection.

AJ Eklipta Wall Lamp
Arne Jacobsen designed the AJ Eklipta Wall Lamp in 1956 for Rødovre Town Hall, and it has hardly changed since. It is a luminous circle of mouth-blown opal glass on a white lacquered aluminium back. The transparent rim of the glass throws a soft halo onto the wall around it, the small eclipse that gives the lamp its name. The Ø 220 projects 105 mm, still slim enough for most corridors.
Because opal glass diffuses the light evenly, the Eklipta is comfortable to look at directly, which matters in a hallway where you walk towards the lamp rather than past it. Its strength is repetition. Three or four at equal spacing along a passage give a steady rhythm of circles, lit or unlit. The larger Ø 350 and Ø 450 are IP44 rated and have traditionally been used on stairways and outdoors. Our comparison of Flindt, LP Grand and AJ Eklipta sets the sizes side by side.

Where depth earns its place: PH Hat and VL 38
PH Hat Wall Lamp
The PH Hat Wall Lamp belongs to Poul Henningsen's late period. Designed in 1961, it reduces his work on glare to a single brim of white lacquered steel that tilts from 0 to about 67 degrees. The light is entirely indirect, reflected off the rose-painted inside of the shade, a Henningsen device that warms the glow and flatters skin. At 153 mm it sits in the middle of this group.
That tilting brim is what makes it so good on a staircase. You can angle the shade so the light washes the wall and treads while the bulb stays hidden from someone walking down. Created with bedrooms in mind, its discreet profile suits hallways and stairs just as well.

VL 38 Wall Lamp
The VL 38 Wall Lamp is the wall version of the table lamp Vilhelm Lauritzen drew in the late 1930s for Radiohuset, the Danish Broadcasting House in Copenhagen, relaunched in 2016 with LED. A rounded shade tilts down from a curved arm of untreated brass that darkens with use. At 290 mm deep it is the one lamp here that needs room around it: a wide entrance hall, a landing, or the wall above a hallway console, where furniture already keeps people back from the wall.
Its controls suit an entrance: a switch on the rear housing with two dimming settings, and a 4 or 8 hour timer, handy for leaving a light on for someone coming home late. It comes in white or black, both with the brass arm.

Mounting height on a staircase
A stair keeps changing your eye line, so the floor at the bottom is the wrong reference. Measure from the pitch line, the imaginary line running through the front edges of the treads, and set every lamp at the same height above it. A row mounted this way climbs with the stair and reads as one composition.
- Keep the lamp above head height for someone walking the stair, so nobody has to duck or lean away from it. Deeper lamps such as the VL 38 need more clearance than a flat Flindt.
- Light the top and bottom of the flight first. These are the steps where a missed tread matters most; a downward wash from a Flindt or a tilted PH Hat picks out the edges clearly.
- Check the view from both directions. Going down, you look at the wall ahead and below, where an exposed source would catch you.
- Mind the handrail. On a narrow stair with a wall-mounted rail, the lamp's projection and the rail together decide how much width is left.
Corded or hardwired
The PH Hat offers the clearest choice. The corded version has a 2.4 m white cord with a plug and a switch on the wall box, and weighs 1.8 kg. The hardwired version, with or without its own switch, weighs 3.5–3.9 kg. Corded suits a rented flat or a wall with no connection point; hardwired is tidier in a corridor, where a cord running down the wall sits right at hip and shoulder level. The VL 38 is a corded lamp with a 3.3 m cord and an external LED driver with plug, so plan for a socket nearby. The Flindt requires installation by a certified electrician. For the AJ Eklipta, confirm the connection for your chosen size. Any hardwired lamp is a job for a qualified electrician.
Which one where
For the narrowest corridor, or a hall that continues from an outdoor entrance, the Flindt is the natural answer. For a long passage that wants a calm rhythm, repeat the AJ Eklipta. On a staircase where glare control matters most, the PH Hat's tilting shade gives you the most say over where the light falls. Where there is space to spare, the VL 38 brings warmth, a dimmer and a timer. To compare these with other designs and finishes, see the full range of wall lamps.
