Stage LightingThe GLP impression X4 Bar uses high output RGBW LED’s that are packed tightly to give a full batten of light, with 20 LED’s used in the 40? long X4 Bar 20 and 10 LED’s used in the shorter 20? X4 Bar 10. High quality optics ensure a smooth, homogenized output across the batten through a broad pallet of pastel and saturated colors. This allows for subtle graduated fades, or for distinct color breaks between LED’s.
