A neon diamond lights the workshop as its maker checks the finished shape. The glass tube light follows angular facets from a broad upper edge to a low triangular point. Small clips fasten the tubes to a steel test frame, and dark cables lead toward a separate control cabinet. The maker's hand rests on its switch while he watches the pale violet glow.

His striped navy shirt and mustard work apron stand against shelves of clear, unlit glass curves. An open roller door reveals deep evening blue outside, while a warm task lamp keeps the workshop materials and his expression visible. Reflected violet light spreads gently across the concrete floor. The full-height composition shows the glowing object, its support and the person checking it as parts of one practical working scene.
