Camera and Photography Equipment Design Sequenti Studio Flash Light by Evgeny Arinin Sequenti is a studio flash light developed for photography. Alternating light sources fire within thousandths of a second, creating a series of images that serve as layers for one lighting setup. The light can then be edited in software, changing intensity and color temperature, switching single sources or groups on or off and applying color filters. A high-intensity LED source is cooled by an aluminum heat sink and silent fans. The glossy plastic body measures 200 by 400 by 600 mm and has a leather handle for adjustment along three axes. All materials are fire resistant.
