GLP's impression X4 XL uses an array of 55 RGBW high-output LEDs coupled with a 7° to 50° zoom range, producing light that can throw for extremely long distances. The optical system gives a sharply defined beam with a hard edge in the lower zoom range while remaining homogenous and soft-edged at wider angles, all in the same baseless design of the impression series. A full RGBW output also has additional variable color temperature correction control. Also featured are a variable speed electronic strobe, smooth full range dimming with no color shift, and 16-bit movement. The fixture’s individually controllable LEDs allow a range of different patterns to be displayed, including arrows, numbers, letters, and more, either from stock or user-generated patterns.
