Good compact and unexpensive lighting bar. Fits 35mm diameter speaker stands (such as Millenium or K&M etc), to give a secure support. I prefer using this Truss with 35mm speaker stands to 28mm diameter lighting stands as they are generally more sturdy, stable and can support more weight. Our band use this with four LED flat panel floodlights/ of foure PAR 56 Cans. Does the job and compact enough to fit on back set of the car. Perfect, but you need to order fittings (bolts and wingnuts) separately
