GLP Impression X4 Bar 20

The GLP impression X4 Bar 20 is a high-performance RGBW pixel batten that delivers a full, even line of light with the build quality and optical finish that has made GLP a standard in professional touring. Twenty 15-watt RGBW LEDs are packed tightly behind precision-machined optics, producing a smooth, homogenized output across the whole bar with a broad palette of pastel and saturated colors. Because the LEDs are true RGBW, colors fade without the green-shift or dimming you see on RGB-only fixtures, which makes this unit a favorite for both hard-wash work and delicate color work over performers. With 16-bit control on every channel, including 16-bit tilt and color mixing, movement and fades are glass-smooth even at slow speeds, and the bar handles everything from subtle atmospheric wash to high-impact strobing effects.

The feature set on this fixture goes well beyond a basic LED batten. A high-speed 7:1 motorized zoom sweeps from 7 to 50 degrees, turning the same fixture into either a narrow-angle light curtain or a wide wash light without ever re-rigging. The 16-bit tilt mechanism moves through a 210-degree range, letting the bar follow the geometry of a stage, a truss run, or an architectural line. A built-in CTO function shifts output from 2500K to 10000K, so warm-to-cool color temperature work is handled inside the fixture rather than with filters. DMX control offers full pixel mapping capabilities, meaning every one of the 20 LEDs can be addressed individually for pixel-mapped effects, chases, and text or graphic displays.

For a used impression X4 Bar 20 in working condition, this is one of the most versatile fixtures you can add to a lighting inventory at the price. It slots into touring rigs, theater and house-of-worship installations, venue trusses, broadcast and stage productions, and architectural lighting projects with equal ease, and it scales from a single accent unit on a small stage to a full pixel-mapped array on a large show. The compact batten form factor keeps rigging light and cabling simple, while the DMX pixel modes make it a serious creative tool rather than just a wash source. If you are upgrading a rig with aging RGB battens, building a lighting package that needs one fixture to do the work of several, or looking for a dependable GLP fixture to own or rent out, this impression X4 Bar 20 brings professional-grade color, optics, and control to your next production at a competitive used price.
