Up & Down Wall Lights

What the double beam actually does

An up and down fitting sends light in two directions from one box on the wall. Rather than putting a pool of light on the ground under it, it draws two triangles on the wall itself, one rising and one falling. On a house front that gives the elevation some depth after dark and picks out the texture of brick or render. Indoors it lifts a corridor without the flat, even wash you get from a ceiling fitting, and it does it at a fraction of the wiring.

Outdoors: rating the fitting to the wall

About half of these are made for outside, and the rating tells you where each one can go. IP44 handles splashing and suits a sheltered wall or a porch. IP54 adds dust protection and copes with driving rain on an open elevation. IP65 is fully jetproof and is the right answer on exposed ground, near a driveway, or anywhere the fitting will be hosed. The rating is in the title and the specification on every product page, so match it to how exposed the wall really is.

Indoors: plaster fittings you can paint

Several of the indoor designs are cast gypsum, made to be painted the same colour as the wall so the fitting disappears and only the light remains. They are usually recessed or half-recessed into the plaster, which means deciding on them before the wall is finished rather than after. The effect is worth the planning: in a hallway or up a staircase, a run of painted plaster uplights gives you rhythm and light without a single visible fixture.

Beam angle and how far apart to space them

The narrower the beam, the sharper and more separate the two triangles. A tight beam gives you a dramatic scallop and wants generous spacing so the shapes do not overlap into mush. A wider beam blends into a more even wash and can go closer together. As a starting point, space them at roughly twice the distance from the fitting to the ground, then adjust by eye. Getting the spacing even matters more than getting it exactly right, because the eye reads the rhythm before it reads the gap.

Lamps, colour temperature and adjustability

Most of these take a GU10, which makes the beam angle something you choose and can change later by swapping the lamp. The rest are integrated LED with the beam fixed by the manufacturer. Warm white around 3000K suits brick and render, while a cooler 4000K reads as crisper on grey render and modern cladding. Check the output of each aperture as well, because some designs split the light evenly up and down while others weight it towards one direction.

Fitting them, and the mistake to avoid

Height is the thing people get wrong. Mounted too high, the downward beam scatters before it reaches the ground and the upward beam runs off the top of the wall. Somewhere between 1.8 and 2.2 metres suits most house fronts. Check what is directly above the fitting too, because a soffit or an overhanging sill will cut the upward beam off short and leave you with a hard line. Outdoor mains wiring is work for a qualified electrician.
