Lighting Your Artwork: Choosing LEDs, Battery Lights, and Power Supplies

Good booth lighting makes the work easier to see without becoming the first thing visitors notice. A fixture that looks bright in a product listing may create reflections on glass, uneven patches on a painting, or a power demand your show setup cannot support. Plan the light around the work and the venue.

Identify the problem first

Photograph your work under the lighting conditions you expect. Is the booth too dark, is one wall in shadow, or do glazed pieces reflect the fixtures? More lights will not solve every problem. A different angle or a less reflective display position may matter more than additional brightness.

Measure the distance from the planned mounting point to the artwork. Compare beam spread and adjustability, not just total output. Narrow beams may suit individual objects; broader illumination can help a wall feel consistent.

Read the color specifications

Color temperature describes whether light appears warmer or cooler; color rendering concerns how faithfully it shows colors. The U.S. Department of Energy explains these distinctions and CRI’s limitations. For art, a published high color-rendering specification is a useful starting point, followed by viewing your own work under the fixture.

Compare the painting or print with a familiar reference under your usual studio light. Look particularly at skin tones, reds, neutral grays, and subtle dark areas. Avoid mixing visibly different light colors across the same wall unless it is an intentional presentation choice.

Calculate power before buying batteries

Add the rated wattage of the fixtures you plan to run. As an illustrative calculation, four 10-watt lights total 40 watts. A battery labeled 200 watt-hours would offer five hours at that load in an ideal calculation; actual runtime is lower or different because of conversion losses, operating settings, temperature, and other equipment.

Use the power-supply manufacturer’s runtime guidance and test the complete arrangement before relying on it. Leave reserve capacity for a longer day. A battery’s watt-hour rating, its maximum output, and its available connectors answer different questions; all must match the intended load.

Check mounting and venue approval

Use fixtures and attachments approved for your display system. Read the equipment’s indoor or outdoor rating and keep cords and connectors within their stated conditions. Ask the organizer about electrical rules and supplied power. Route cables so they do not cross browsing paths or pinch inside folding components.

For framed work, move around the booth and look for glare from several heights. Test the checkout area too: customers should be able to read labels and examine a purchase without staring into a light.

A useful pre-show test

1. Mount the intended lights on the actual display.
2. Evaluate color and reflections with representative artwork.
3. Run the complete system for the expected show duration.
4. Record settings, runtime, and spare equipment needed.

Choose lighting that solves a visible problem and works for the full day. Consistency and reliability are more valuable than an impressive brightness claim alone.
