A vehicle display contains curved paintwork, glass and interior materials; a parts stand may combine chrome, matte surfaces and small labels. Start with the surfaces and viewing positions. Extra brightness alone does not make an exhibit readable or guarantee visitor attention.
Walk around the paint, not just one viewing point
Test a sample fixture with the vehicle or representative paint panels. Look from the aisle, front, sides and intended photo positions. Konica Minolta explains that metallic and pearlescent colours vary with viewing angle. Check where reflections obscure body contours or create bright patches. Move and aim one fixture at a time. Adding several small lights can add several reflections; it does not automatically soften the result.
Choose colour performance by testing real materials
CRI is useful screening information, but a value of 95 is not a universal automotive requirement or a guarantee of paint appearance. DOE’s TM-30 guidance describes a broader set of colour-rendering measures. Ask for available colour data and compare the actual paint, upholstery and graphics under candidate lights. Formal paint matching needs the specified evaluation method, not a booth-light CRI claim.
Compare warmer and cooler white light rather than assigning one colour temperature to electric cars and another to luxury cars. Verify whether a model’s CCT is fixed at purchase or adjustable on the fixture. For recordings, test the intended camera, exposure, shutter and dimming settings; visual approval does not establish camera performance.
Separate bodywork, interiors and small products
Adjust the bodywork lighting while checking windscreen reflections, then assess whether the interior needs a separate light. For parts, aim light at the relevant finish and keep labels readable without direct glare. Test the apparent size and position of any reflected source; do not rely on a universal 30–45-degree aiming rule. Add fixtures only when a coverage test identifies a gap.
For a backlit brand graphic, test the print, diffuser and internal lighting together. Match the module or strip to the complete panel’s depth, thermal conditions and electrical design; a lightbox component is not automatically compatible with every panel.
Check the installation and the current event manual
Verify permitted mounting points, clamp fit, loads, cable routes and power orders. Use the current SEMA exhibitor manual or the resources for your actual show. Confirm lighting, electrical and vehicle-display rules with the organiser; approval is not implied by a product collection or event name. Check documents for the exact equipment and assembly.
Rehearse the complete display
Set up the layout before shipping and check glare, coverage, heat, access and photographs. Determine quantities from the vehicle, viewing positions, fixture data and available mounts rather than a booth-size table. Send the layout, surfaces, venue and installation date through our contact page to discuss suitable options and the order-specific schedule.
