impression X4

The GLP Impression X4 brings power, flexibility and practicality in a new breakthrough design. Behind the unique looking front lens, the X4 offers 19 RGBW LED’s, each rated at 15W providing a homogenized beam with high output that can cut through cleanly on todays’ stages and studio floors. A 7:1 zoom ratio offers a fully variable beam from a tight 7 degrees, to a wide 50 degrees whilst remaining even at all times. Its lightweight, ergonomic baseless design, 16-bit movement and low power consumption add to its feature set.


Additionally, a unique feature of the GLP Impression X4 is the ability to individually control the intensity the 19 LED’s, allowing you to program unique looks and animations on the fly.

Weighing just 17.5 lbs., the impression X4 delivers high output with even color mixing across the beam at all angles, and offers a wide color pallete from soft pastels to deep saturates.

White X4 swirls into action with Trey Anastasio band

Since becoming the first production designer to adopt GLP’s new X4 platform (back in 2012 with My Morning Jacket), Marc Janowitz (of e26 Design) has been a frequent user, deploying 30 of MMJ’s touring fixtures for Trey Anastasio’s 2012 Traveler tour which followed immediately after. More recently he turned to 18 of the smaller X4S LED heads for last year’s Cage The Elephant tour.
