How to Light Artwork at Home Without Glare or Fading

You hung the painting, stepped back, and it looked flat, or worse, a bright white glare sat right across the middle of the glass. Knowing how to light artwork at home is mostly about angle, colour and brightness, and once you get those three right, even an inexpensive print starts to look like it belongs on the wall.

I light rooms for a living, and art is where clients most often spend money on fittings and still get it wrong. Here is the method I use, with the numbers that matter and the shortcuts that work in an ordinary house.

The three rules for how to light artwork

Every good art lighting scheme comes back to three things.

• Angle. Light should hit the centre of the piece at about 30 degrees from vertical. Steeper than that and frames cast long shadows over the top of the image. Shallower and the light bounces off glass straight into your eyes.
• Colour. Use a colour temperature of 2700 to 3000 kelvin for most paintings and photographs in a living space, and a colour rendering index (CRI) of 90 or higher. Low CRI bulbs make reds look brown and skin tones look grey.
• Contrast. The art should be roughly two to three times brighter than the wall around it. Much more and it looks like a museum spotlight; much less and the eye does not notice it at all.

If you are unsure how warm or cool a bulb will look in your room, our guide to how colour temperature changes a room explains the scale in plain terms.

Choosing between picture lights, spots and track

Picture lights

A picture light mounts on the wall or the frame and arches over the top of the piece. It is the easiest option for renters and for single pieces, and plug in or battery LED models need no electrician. Choose one whose bar is roughly one third to one half of the frame's width. A 90 centimetre wide painting suits a 30 to 45 centimetre light.

The weakness is coverage. Picture lights sit close to the canvas, so they light the top third strongly and fade towards the bottom. They suit wide format works better than tall portraits.

Ceiling spots and adjustable downlights

Recessed adjustable downlights, sometimes called gimbals or eyeballs, give the most even, invisible result. They need planning and usually an electrician, but they light the whole piece from a distance and leave the wall clean.

Track lighting

Track is the flexible choice if you rotate pieces or have a gallery wall. Heads slide and swivel, so you can retarget them when you move a frame. Modern slim tracks in white or black disappear against most ceilings.

How far from the wall to place a ceiling light

The 30 degree angle gives you a simple calculation. Measure from the ceiling down to the centre of the artwork, then multiply that figure by 0.58. The answer is how far out from the wall the light should sit.

Take a typical room with a 2.4 metre ceiling and a painting hung so its centre is 1.5 metres from the floor. The drop from ceiling to centre is 0.9 metres. Multiply by 0.58 and you get about 52 centimetres, so place the downlight roughly half a metre from the wall. On a 2.7 metre ceiling with the same painting, the drop is 1.2 metres and the light moves out to around 70 centimetres.

For a frame wider than about 1 metre, use two lights spaced so their beams overlap at the centre, rather than one wide flood. A beam angle of 24 to 36 degrees suits most domestic pieces.

The advice I disagree with: brighter is always better

Many people assume that if a painting matters, it should be lit as brightly as possible. In a home, that usually backfires. A very bright spot on an otherwise dim wall turns the art into a glowing rectangle, flattens its texture and makes the rest of the room feel gloomy by comparison.

The better approach is to raise the general light in the room first, then add accent light on the art at two to three times that level. This is the same layering principle that makes any room comfortable, which we cover in how to layer lighting in a living room. Put the art lights on their own dimmer, too. You will want them brighter on a dull winter afternoon and much softer in the evening, and our guide to installing a dimmer switch shows what is involved.

Protecting the art itself

Older halogen and incandescent bulbs gave off ultraviolet light and a fair amount of heat, both of which fade pigments and dry out canvases over the years. Good quality LEDs emit almost no UV and very little forward heat, which makes them the safest option for anything you value.

Still, a few habits help. Keep picture light bars at least 15 centimetres away from the surface of the canvas. Avoid hanging works on paper, such as watercolours and prints, where direct sun falls on them for hours a day. For glazed pieces, consider anti reflective, UV filtering glass when you next reframe; it cuts glare far more than any change of light angle.

Fixing glare on glass

If you see a bright reflection on a framed print, the light is either too close to the wall or too directly in front of where people stand. Move the light further out, or tilt the frame very slightly forward at the top using a small spacer behind the bottom edge. Even 1 to 2 centimetres of tilt can move the reflection out of your eye line. If that is not enough, matte acrylic or museum glass solves the problem for good.

Frequently asked questions

What colour light is best for artwork?

For most paintings and photographs in a home, 2700 to 3000 kelvin with a CRI of 90 or more works best. Warm white flatters oil paintings and wood frames. Very cool or modern works with lots of blue and white can take 3500 to 4000 kelvin if the rest of the room is also lit cooler.

Are LED lights safe for paintings?

Yes, good quality LEDs are the safest common light source for art. They give off almost no ultraviolet light and little heat at the beam, which are the main causes of fading and drying. Choose a reputable brand with a high CRI rating.

Should a picture light be on all the time?

No. Use it when you are in the room or want the piece to be seen, much like any other accent light. Even LED light causes very slow fading over decades, so turning it off when nobody is there, or using a timer, is kinder to the work and costs less to run.
