LED light bar set EUROLITE PMB-8 COB QCL 30W with RGBW diffusion discs

The EUROLITE PMB-8 COB QCL 30W with RGBW diffusion discs is a compact LED light bar set designed for stage, event and accent lighting. It combines a 30W COB QCL light source with a set of interchangeable RGBW diffusion discs that soften the beam while enabling mixed-color effects. The linear form factor and modular diffusion options provide a balance between direct illumination and gentle, even color wash for installations, rental rigs and mobile setups.

Advantages

This LED light bar set delivers a high-output 30W COB QCL emitter that produces uniform light across the bar, while the RGBW diffusion discs allow quick change of color characteristics and beam softness without additional fixtures. The compact design simplifies integration into trussing, stage fronts or architectural accents and reduces the need for multiple fixtures. Built for flexibility, the unit supports versatile color mixing and straightforward visual control in environments where compact linear lighting is required.

Suitable for

• Stage edge lighting and low-profile stage washes
• Event and corporate presentations requiring accent color effects
• Rental and touring setups where quick reconfiguration is needed
• Architectural and retail accent lighting to create even colored washes

When it may not be suitable

The PMB-8 is intended primarily for color accent and wash applications; it is not designed as a high-precision theatrical profile or spotlight for sharply defined beam shaping. For projects that require extremely narrow beams, hard-edged projection or very high lumen output over long throw distances, a dedicated profile fixture or high-power moving head may be more appropriate.

Key specifications

• Light source type: COB QCL LED, 30W total power
• Color system: RGBW mixing via LED emitter and interchangeable diffusion discs
• Form factor: linear light bar, compact length suitable for mounting on truss or surfaces
• Output character: softened, even wash with diffuser discs; configurable color tones
• Use cases: designed for stage, event, rental and installation lighting

How to use

Install the light bar according to mounting requirements using appropriate brackets or truss clamps. Fit the selected RGBW diffusion disc to achieve the preferred beam softness and color character. Power and control the unit as specified by the manufacturer’s instructions; use DMX or compatible control interfaces if available to program color mixing and intensity. Position the bar to provide even wash or accent illumination and test color combinations at operating intensity before performances or events.

What to consider before purchase

• Verify mounting and physical dimensions to ensure compatibility with planned rigging or installation points
• Confirm control compatibility (DMX or other control protocols) with existing lighting desks or controllers
• Assess whether the softened wash and RGBW mixing meet the project’s beam shape and color fidelity requirements

Usage recommendations

For best results, combine the PMB-8 with complementary fixtures to provide backlight or key lighting where needed. Use the diffusion discs to match neighboring fixtures’ beam characteristics and perform color calibration on-site to ensure consistent mixes across the stage or installation.
