Thanks to the quick-release design, you can seamlessly connect the tube light, battery grip, and lighting control accessories for wireless lighting on the go, significantly boosting efficiency. When compacted, the tube light is a mere 42cm / 16.5in long, with the handle weighing just 900g / 31.7oz, making it 75% lighter than comparable products. The lightweight design allows for effortless storage in any camera backpack or toolbox, ensuring swift and convenient transportation.

The versatile mounting options allow for handheld lighting using the handle or other setups connected via 1/4″ and 3/8″ standard ARRI locating pins, NATO rails, and other interfaces for easy installation and flexible lighting configurations. Its distinctive triangular cross-section lanyard design improves ergonomics, minimizing fatigue during prolonged handheld use and preventing accidental drops when placed on a flat surface. Even with a 0.5m/5600K setup and a PC diffuser, the light maintains an illuminance of 2,350lux, excelling in color accuracy with a CRI Ra of 96+ and TLCI of 98+. The color deviation (△UV) ranges between -0.0005 to +0.0005 at 2700K and 5600K, ensuring professional color performance and accurate reproduction of natural daylight.

With meticulous craftsmanship, it holds an IP65 rating for dust and water resistance, making it suitable for challenging outdoor shooting conditions and unforeseen situations during night shooting. The soft, uniform light with a broad beam angle is perfect for capturing seamless and elegant moments in portrait photography.
