A picture light<\/strong> should allow an artwork to be seen clearly, without distracting reflections or shadows that obscure its details. When choosing one, consider the size of the picture, the depth of its frame, its surface finish and the positions from which it will be viewed.<\/p>\n\n\n\n

The choice also forms part of the interior design. A light positioned above the frame becomes part of the wall composition, while a ceiling spotlight creates visual separation between the lighting and the artwork. Both approaches can work, provided the light distribution suits the picture\u2019s format and position.<\/p>\n\n\n\n

What to consider when choosing a picture light<\/h2>\n\n\n\n

Before deciding on the finish or shape of the luminaire, establish what it needs to illuminate and from where.<\/p>\n\n\n\n

Criterion<\/strong><\/td>What to check<\/strong><\/td><\/tr>
Artwork dimensions<\/td>The light should reach the area you want to highlight without leaving excessively dark patches.<\/td><\/tr>
Frame depth<\/td>The upper edge should not cast a distracting shadow across the image.<\/td><\/tr>
Glass or glossy surfaces<\/td>The light source should not appear as a reflection from normal viewing positions.<\/td><\/tr>
Colour rendering<\/td>The light source should allow the colours to be appreciated accurately.<\/td><\/tr>
Adjustability and optics<\/td>The beam should suit the artwork\u2019s format and the lighting distance.<\/td><\/tr>
Power supply and controls<\/td>The planned installation and dimming system should be compatible with the selected model.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Light that reveals the colours<\/h3>\n\n\n\n

The colour rendering index, or CRI, helps assess how a light source renders colours. For lighting art, look for LEDs with high colour rendering, using values above 90 as a quality reference.<\/p>\n\n\n\n

This specification must be checked for the actual light source. In a luminaire with a replaceable lamp, colour rendering depends on the lamp fitted.<\/p>\n\n\n\n

A beam suited to the format<\/h3>\n\n\n\n

A small artwork and a large composition have different lighting requirements. The beam angle and the distance from the luminaire determine the area that receives light.<\/p>\n\n\n\n

Narrow beams can highlight smaller pieces or illuminate from greater distances. Wider distributions help cover larger surfaces. When the artworks on display change, suitable adjustment and optics make it easier to adapt the lighting.<\/p>\n\n\n\n

A picture light above the frame or lighting from the ceiling?<\/h2>\n\n\n\n

A picture light mounted above the frame creates a direct visual relationship with the artwork. It can be a suitable option when the picture has a fixed position and the luminaire is intended to become part of the composition.<\/p>\n\n\n\n

Ceiling lighting offers a different approach: the artwork retains its presence on the wall, while the light comes from another plane. Adjustable spotlights allow light to be directed towards a particular piece; track systems make repositioning easier when a collection is rearranged.<\/p>\n\n\n\n

If the aim is to illuminate a wall displaying several artworks evenly, wallwashing can also be considered. Its effect differs from lighting each picture individually: it brings the display together rather than creating a separate accent on each piece.<\/p>\n\n\n\n

How to avoid reflections and shadows on a picture<\/h2>\n\n\n\n

The positioning should be checked from the places where the artwork will be viewed. In a living room, for example, it is useful to assess the result both standing up and sitting on the sofa.<\/p>\n\n\n\n

For ceiling spotlights, a common starting point is to direct the light at an angle of approximately 30\u00b0 from the vertical<\/strong>. This helps manage shadows cast by the frame and the viewer, as well as reflections on glazed surfaces.<\/p>\n\n\n\n

The final position requires adjustment according to the ceiling height, frame and artwork\u2019s finish. The 30\u00b0 rule should not automatically be applied to every picture light mounted above a frame.<\/p>\n\n\n\n
