Display case lighting is its own discipline. The fixtures are small, the viewing distance is close, the merchandise is often valuable – and the light must sell the object without harming it. This guide collects our planning tools, application notes and troubleshooting articles in one place, written for jewelry retailers, museum professionals, showcase manufacturers and lighting buyers. Industry analysts project magnetic track systems to account for more than half of track lighting within three years (2026 China track lighting industry report, ChinaBGAO) – and display cases are where low-voltage magnetic systems fit most naturally.
