GML CURTAIN BAR IP All-Weather Narrow Beam LED Bar
The GML CURTAIN BAR IP is built to generate dense light curtains, sharp aerial planes, and dynamic kinetic sweeps for concerts and festivals (IP66). It incorporates 72 × 4W RGBW 4-in-1 LEDs aligned into a continuous linear strip with a high-transparency small-angle optical system outputting an ultra-narrow 3° beam.
3° Optical Definition and Structural Rigging
The 3° field projection creates defined mid-air light sheets that maintain intensity over long throw distances. Housing mechanics accommodate vertical and horizontal orientations via Omega clamps, along with 4-directional modular joining hardware for expanding arrays horizontally and vertically without pitch distortion.
Network Protocols and Connectors
Network integration covers Art-Net and sACN alongside DMX512 and RDM control across 4 DMX operational profiles (9, 41, 144, and 153 channels). The unit features an OLED screen with 4 touch keys, firmware upgrade via DMX, weatherproof AC power connections, and 3-pin/5-pin XLR terminals. Dimensions measure 1002 × 142 × 90 mm with an 8 kg net weight.
