Art Lighting: Seeing Your Art in the Best Light

Whether lighting an art gallery, museum, an art studio or your living room, selecting the best lights for a work of art requires knowledge and understanding of footcandle requirements, beam spread, color temperature and color rendering.

Why is lighting important in galleries?

Lighting is an essential feature in art galleries, as it can enhance the art viewing experience and bring artworks to life. Without proper lighting, art pieces can appear dull, muted or distorted. Thus, art galleries need to select the correct lighting setup for each individual artwork to accurately represent the artist’s vision.

Additionally, lighting also has a major impact on the ambiance of a space and can set the mood for an art gallery exhibit or presentation. Art galleries and museums (not to mention your own home!) can use specific lighting solutions that will create an inviting atmosphere while bringing out all the details in the artwork on display. Ultimately, good art lighting is key in conveying both emotion and detail.

Key aims of lighting art

The four primary aims of lighting artwork are as follows: visibility, color rendering, focus and preservation. Achieving a balance between these aims is crucial to creating an optimal viewing environment for artwork.

1. Visibility

Lighting should ensure that the artwork is clearly visible to viewers. Proper illumination helps to reveal details, colors and textures, allowing viewers to appreciate the nuances of the piece.

2. Accurate color rendering

Lighting should reproduce colors accurately to maintain the integrity of the artwork. Proper color rendering ensures that viewers see that artwork as intended by the artist, without distortions or shifts in color perception.

3. Highlighting focal points

Lighting can be used strategically to emphasize specific areas or elements within the artwork. This helps guide the viewer’s attention to key focal points, enhancing the overall visual experience.

4. Preservation

Light can cause damage to artworks over time, particularly sensitive materials like pigments and paper. Proper lighting aims to minimize the potential for damage by controlling factors such as intensity, duration and UV radiation, thus contributing to the preservation of artwork.

What light do artists use?

In addition to natural sunlight artists often use task lighting, such as desk lamps or clamp lights, to illuminate specific areas where detailed work is being done because it provides focused, consistent, and concentrated illumination. Task lighting can be anything from incandescent bulbs, adjustable LED lights, daylight bulbs, fluorescent lamps and halogen bulbs. This wide range of options means that color rendering is often different than what the artist might have used while designing. For this reason, when accurate information can’t be found through research, the best route is to choose a color option that best highlights the individual piece or a group of pieces being displayed together.

5 tips for the best lighting in an art gallery

Creating the besting lighting in an art gallery is essential to enhance the visual impact of the artworks and provide a positive viewing experience. Remember to tailor the lighting design to the specific needs of the artworks and the gallery space. Regular maintenance and monitoring of the lighting system is also crucial to ensure consistent and optimal conditions for exhibiting art. Here are five tips for achieving optimal lighting in an art gallery:

1. Use adjustable lighting fixtures

Install adjustable lighting fixtures that allow you to control the direction, angle, and intensity of the light. This flexibility enables you to highlight specific artworks, control glare and adapt to different types of art.

2. Balance natural and artificial lighting

Integrate natural light when possible, but control it to prevent direct sunlight from causing damage to artwork. Supplement natural light with artificial lighting to maintain consistent illumination throughout the space, especially during evening hours and cloudy days.

3. Consider color temperature

Choose lighting with a color temperature that complements the artwork. Warm color temperatures (e.g 2700K) can enhance traditional art, while cooler temperatures (e.g 4000K) may be suitable for contemporary pieces. Consistency in color temperature across fixtures ensures uniformity in the gallery space.

Natural lighting is considered by many to be the best light for displaying fine art because sunlight has the highest CRI (Color Rendering Index), which is the measurement of a light source’s capacity to accurately reveal the various colors of an object. In other words, it’s the truest representation of the actual colors in a work of art.

Color-tunable lighting is a lighting technology that allows users to adjust the color temperature and intensity of light. It combines LEDs of different color temperatures into single bulbs or strips.

Color tuning is ideal for installations where the owner of the space wants flexibility and control over lighting. The ability to alter both the hue and brightness of lighting enables art displays to be tailored for a particular piece or artist, creating more depth and impact for viewers. The result is an enhanced viewing experience: Patrons see the work as the artist intended.

4. Minimize UV exposure

UV exposure can lead to fading and deterioration of pigments and materials. Protect pieces by reducing UV radiation in the gallery. Use lighting fixtures with UV filters or select bulbs that emit minimal ultraviolet (UV) radiation. Install UV filtering glass in frames or UV filtering film on windows. 

5. Create layered lighting

Implement a layered lighting approach to achieve depth and dimension in the gallery space. Combine ambient lighting for overall illumination with accent lighting to highlight specific artworks or areas. This creates a dynamic visual environment and emphasizes the gallery’s architecture.

Directional lights, such as track lighting and adjustable recessed lighting, offer the most flexibility for aiming the light at the desired art piece.

The primary advantage of track lighting is the capacity to aim spotlights where needed. Track lights also offer the benefit of retaining their proper color temperature even when dimmed.

However, this type of lighting is often seen as cost-prohibitive for smaller galleries with budget concerns. The good news is that the cost of LED track lighting is becoming comparable to its halogen counterparts. So, it may be worth pricing out LED options for your client and including lifetime maintenance costs as part of the conversation.

In addition to professional track lighting, trimless adjustable recessed lighting is another option. Adjustable recessed lighting provides a cleaner, more high-end look, and is often preferable in low-ceiling applications.

Types of light sources to use in an art gallery

Gallery lighting requires a careful selection of light sources to ensure that artworks are displayed effectively while considering factors like color render, heat emission and UV radiation.  The most common light sources used in gallery lighting are:

1. Filtered natural/sunlight
