Lighting bar EUROLITE Zoom4Bar QCL RGBW 4-in-1 — zoomable LED wash bar with QCL LEDs

The EUROLITE Zoom4Bar QCL RGBW 4-in-1 is a zoomable LED wash bar equipped with QCL RGBW 4-in-1 LEDs designed for stage, event and architectural lighting. Its linear form factor and adjustable zoom enable both narrow and wide beam coverage, delivering smooth color mixing and uniform washes across flat surfaces. The fixture combines compact physical dimensions with professional output suited to front wash, backlight and subtle color accents in a variety of environments.

Advantages

The Zoom4Bar offers adjustable beam angle through a mechanical zoom system, allowing precise control of spread from tight beams to broad washes. Integrated QCL 4-in-1 LEDs provide smooth RGBW color blending and consistent color temperature when using white tones. The linear design facilitates discreet mounting in trusses, on floors or on walls while producing even light distribution. Built-in control options and efficient LED technology reduce power consumption and heat compared with comparable discharge fixtures.

Suitable for

• Stage front wash and backlighting for theatre and concerts
• Event lighting for weddings, corporate events and presentations
• Architectural façade and cove lighting for indoor and semi-protected outdoor locations
• Studio and video productions requiring even color washes

How to use

Install the wash bar on a suitable truss, floor stand or wall bracket and ensure secure fastening and correct orientation for the intended wash direction. Connect power and DMX control following local electrical safety rules and the fixture’s wiring requirements. Use the zoom mechanism to set the desired beam spread for the coverage area, and select color and intensity via DMX channels or the onboard control panel. For multi-fixture setups, address each unit with unique DMX addresses and configure scenes or chases to achieve synchronized color washes and dynamic effects.

Usage recommendations

Position the Zoom4Bar at a consistent height and angle for even washes; use a mix of narrow and wide zoom settings to shape the light across different stage depths. Allow adequate ventilation space around the fixture and avoid exposure to heavy rain or excessive humidity. For color-critical applications, test color mixes on-site and adjust white balance using the fixture’s white channel to match other light sources.
