This is a Square Perfect SP1 Continuous Light Kit with Boom, a photography lighting system designed for studio use. Includes softboxes, light stands, a boom arm, and light bulbs for professional photo and video shooting. Softboxes help to soften the light stream, remove shadows, and produce more uniform lighting for better portraits and still life photography, content creation, as well as self tapes. The light stand height is adjustable. The boom arm can be adjusted for length and angle, and includes a sandbag for stability and precise lighting. The full kit is designed to be lightweight and easy to collect, making it portable for outside use. This has been very lightly used. One knob's plastic broke off but still has screw to tighten. Can be replaced easily if desired (pictured) In great condition. Comes with 2 large bulbs for boom light and 11 standard bulbs for 2 light boxes. Each light box contains 5 bulbs that can be used independently. All in original packaging and carry case. Animal free/smoke free environment. OBO
