The TP-B4 4-Light Bracket for KNOWLED Tube Lights from Godox is a sturdy bracket that up to four KNOWLED tube lights can be mounted to, creating a larger light source. It can be used with tubes measuring 2' and 4' in length. Each tube is secured in place using two locking clamps.
The bracket platform has a ball and socket joint that allows it to be positioned at any angle. It has a 5/8" receiver with a locking knob, so it can be used on almost any standard light stand, or even attached to clamps or other devices.
