Leko is a commonly used term for an ellipsoidal reflector spotlight, a focusable fixture that produces a sharp, shapeable beam using an ellipsoidal reflector and lens system.
A Leko, more formally an ellipsoidal reflector spotlight, uses an ellipsoidal reflector and a lens system to produce a tightly controlled beam of light. Internal shutters and accessory slots let lighting professionals shape the beam precisely, projecting hard or soft edges and patterns onto a subject or set. This control makes the fixture a workhorse for focused, directional lighting in production.
In commercial production, theater, and broadcast environments, these spotlights deliver key lighting and projected patterns that define the look of a scene. The fixtures draw significant power and are often dimmed and controlled remotely, so the power and control cabling feeding them must be rated and configured to support stable, repeatable lighting cues. Reliable wiring is essential to executing a lighting design exactly as intended, cue after cue.
Because the shutters and accessories that shape the beam sit close to a hot light source, the fixture and its surrounding equipment are built to handle the heat, and the power feeding it must be rated accordingly to support sustained operation.
At Windy City Wire, the emphasis on low-voltage power and control cable supports the lighting systems that fixtures like the Leko depend on. Supplying dependable cable for power and control helps ensure that spotlights respond predictably to dimming and that their carefully shaped beams stay consistent throughout a production.
