A picture light is mounted above the frame and angled down, so the glow falls across the canvas, not into your eyes.
Every home has a wall that people stop at. It might be a painting you carried home from a trip, an old family portrait, or the mirror where your day begins. The right wall light turns that spot from something you pass into something you notice, and it is one of the simplest lighting upgrades you can make.
Museums have known this for centuries: art is only as good as the light that falls on it. At home, the same is true of mirrors. A single ceiling light leaves shadows under your eyes and a dull grey cast across a canvas. A light placed at the wall, at the right height and the right width, fixes both. In this guide we explain how to choose and place a picture light above a painting, and a vanity or mirror light above or beside a mirror, then show three Vidirlighting wall lights that do each job beautifully.
The short version
- For a painting, choose a picture light about one-half to two-thirds the width of the frame.
- For a mirror, choose a light about two-thirds to three-quarters of the mirror’s width, and never wider than the mirror.
- Mount a picture light just above the frame, and a mirror light just above the mirror or at eye level on both sides.
- Warm white light of 2700–3000K flatters both faces and artwork.
Why light a painting or a mirror?
Lighting designers talk about three layers of light in a room. Ambient light fills the space, usually from the ceiling. Task light helps you do something, like shaving or applying make-up. Accent light draws the eye to something you love. A mirror light is task light; a picture light is accent light. Most homes have plenty of the first layer and very little of the other two.
Adding a wall light at the right spot changes how a room feels at night. Instead of one flat wash from above, the room gains a few warm pools of light at eye level. Your painting becomes the first thing guests see. Your reflection looks like you, without harsh shadows. And because wall lights sit close to what they light, they can stay low and soft, which is exactly what makes a room feel calm in the evening.
Picture light or mirror light?
The two look similar on the wall, but they are designed to do different jobs.
Picture light
Mounted above a frame on a short arm and angled down. It lights the artwork itself, evenly from top to bottom, while keeping the bulb out of sight.
Mirror light
Mounted above a mirror or on both sides of it. It lights the person standing in front, so the face is bright and evenly lit without shadows under the eyes.
Some lights do both. A slim picture light can sit above a small mirror in a powder room, and a long mirror light can wash a wide canvas over a sideboard. What matters most is getting the size and height right.
How to choose the right size
For a painting
Choose a picture light about half to two-thirds the width of the frame. For a frame 60 cm (24″) wide, that means a light of roughly 30–40 cm (12–16″). Smaller lights leave the corners dark; larger ones start to compete with the art.
For a mirror
Choose a light about two-thirds to three-quarters the width of the mirror, and no wider than the mirror itself. For a double vanity with two mirrors, use one light above each mirror, which is why many wall lights are sold as a pair.
How high to mount it
Height decides whether a wall light flatters or glares. Follow these steps when you plan the position with your electrician.
- Hang the painting or mirror first. The light is positioned around the object, so fix the object before you mark the wall.
- Picture light: place it so the light sits about 10–20 cm (4–8″) above the top of the frame, with the head angled down onto the canvas. For tall paintings, a longer arm helps the light reach the lower edge.
- Light above a mirror: mount it about 5–10 cm (2–4″) above the mirror, which usually puts it around 190–200 cm (75–80″) from the floor.
- Lights beside a mirror: mount a pair at roughly eye level, 150–165 cm (60–66″) from the floor, about 70–90 cm (28–36″) apart. Side lighting is the most flattering light for faces.
- Check from where you stand. Before the final fix, hold the light in place and look from your usual position. You should see the glow, not the bulb.
The right colour of light
For both art and mirrors, warm white light of 2700–3000K is the safest choice at home. It gives skin a natural, healthy tone and brings out the warmth of oil paint, wood frames and gilding. Cooler light above 4000K can make a room feel clinical in the evening.
Two more things to look for. A high colour rendering index, ideally CRI 90 or above, shows colours as they really are, which matters when you are matching make-up or admiring a painting. And LED light sources are kinder to artwork than old halogen bulbs, because they give off far less heat and very little ultraviolet light, the two things that fade pigments over time.
Three wall lights for mirrors and art
Each of these Vidirlighting wall lights is designed for a specific spot. Two are classic picture lights in a warm gold finish; the third brings natural travertine and wood to the wall above a mirror. All three are available singly or as a pair.
Curator LED Picture Wall Light
Gold, round wall plate, adjustable arm, integrated LED
A gallery classic in miniature. A round gold wall plate holds a jointed arm and a slim cylindrical bar, with the LED tucked along its underside so the light falls straight onto the canvas. It is sized for the small and medium pieces most of us hang at home: a landscape above a console, a portrait in a hallway, or a small mirror in a powder room.
Arden Picture Light Wall Sconce
Gold, rectangular wall plate, square-profile head
Crisper and more architectural, the Arden pairs a rectangular wall plate with an angled arm and a long, square-profile head. It comes in two lengths. The shorter suits a single framed print or a mirror above a dressing table; the longer is made for statement pieces: a large canvas over a sofa, a gallery wall above a sideboard, or a run of bookshelves.
Travertine Duo Wood Wall Light
Natural travertine, walnut-colour wood, warm light
For the bathroom or dressing-table mirror, this vanity light sets drums of natural travertine on a rounded wooden backplate. Each drum casts warm light down onto the face and the counter below, while the stone’s pores and earthy banding add texture that metal fixtures cannot. Three lengths let you match the light to your mirror using the two-thirds rule.

Five mistakes to avoid
- A light that is too small. A short picture light over a wide frame leaves the corners dark. Use the half-to-two-thirds rule.
- Mounting too high above a mirror. Light from far above casts shadows under the eyes. Keep it just above the mirror, or move to side lights.
- Cool white bulbs. Anything above 4000K makes skin look grey and art look flat at night. Stay with 2700–3000K.
- Mixing finishes at random. Match the metal of the light to the frame, taps or handles nearby, or choose a natural material like travertine and wood that sits happily with both.
- Ignoring the bathroom splash zone. In a bathroom, check the light’s IP rating and keep it away from showers and baths, as local electrical codes require.
Questions, answered
What size picture light do I need?
Choose a light about half to two-thirds the width of the frame. A 60 cm (24″) frame suits a light of about 30–40 cm (12–16″); a 120 cm (48″) canvas suits about 60–80 cm (24–32″).
How far above a painting should a picture light go?
Mount it so the light sits about 10–20 cm (4–8″) above the top of the frame, then angle the head down until the glow reaches the lower edge of the canvas evenly.
How wide should a light above a mirror be?
About two-thirds to three-quarters of the mirror’s width, and never wider than the mirror. For a 70 cm (28″) mirror, a light of about 50 cm (20″) is ideal.
Is it better to light a mirror from above or from the sides?
Side lights at eye level give the most even, flattering light on the face, because they fill in shadows from both directions. A light above the mirror is simpler to install and works well in most bathrooms; combining both gives the best result.
Will LED picture lights damage my painting?
LED light sources give off very little heat and almost no ultraviolet light compared with halogen bulbs, so they are far gentler on paintings and prints. Even so, avoid placing valuable works in direct sunlight.
What colour temperature is best for art and mirrors?
Warm white of 2700–3000K. It flatters skin tones and the warm colours of paintings, wood and gilded frames, and keeps a room feeling relaxed in the evening.
Can I use a picture light above a mirror?
Yes, especially for smaller mirrors in a hallway or powder room. A picture light angled slightly forward lights the person in front of the mirror as well as the mirror frame.
Should I buy wall lights in pairs?
Buy a pair when you light both sides of one mirror, two mirrors over a double vanity, or two matching pieces of art. All three lights in this guide are available as a pair.
