impression X4

The impression X4 features 19 high power RGBW LEDs, each rated at 15W with a 7 ° - 50 ° zoom range. The housing design is based on the legendary, and award winning, impression 90 and 120RZ fixtures including their baseless design and small footprint.

The brand new optical system gives a well defined beam, complete with hard edge in the lower zoom range whilst remaining absolutely homogenous and soft edged at wider angles.

RGBW color mixing, variable CTO and a finely tuned dimming curve are standard in the impression X4.

The impression X4 features individually controllable LEDs allowing a range of different patterns to be created and displayed on the front lenses, including arrows, numbers, letters and much more, either from stock patterns or through user created patterns.
