The GLP Impression X4 XL is a high-output, feature-rich moving head wash light engineered for large-scale concert touring, theatrical productions, and major live events where expansive color washing and dramatic stage effects are required. It is distinguished by its unique four-primary color system, utilizing dedicated red, green, blue, and yellow (RGBY) LED engines. The addition of a dedicated yellow LED significantly expands the color gamut compared to standard RGB fixtures, enabling the creation of vibrant saturated colors, deep ambers, rich pastels, and exceptionally pure, high-quality white light. This makes it an exceptional tool for lighting designers who require precise color matching, subtle tonal shifts, and the ability to fill large scenic elements with consistent, intense color.

The fixture boasts an impressive optical system with a wide zoom range, allowing it to transform from a tight beam for focused effects to an extremely wide wash that can blanket a massive stage area. It incorporates a full suite of professional effects, including a variable frost filter for softening the beam edge, a fast mechanical strobe, and high-quality optics for smooth, even field distribution. Built into a robust housing designed for the demands of touring, the X4 XL features precise 16-bit pan and tilt movement and comprehensive thermal management. Controlled via standard DMX512/RDM or onboard menus, it provides lighting programmers with deep creative control. By combining massive output, superior color technology, and versatile optics, the GLP Impression X4 XL serves as a premier color wash fixture for creating the immersive and dynamic lighting landscapes that define modern large-scale productions.
