I purchased several of these at auction for next to nothing its been a learning experience refurbishing the units and creating a DMX profile for use in Onyx. I am now at the point where I am wanting to add them to my rig..... I am buggered if I can source a mounting bracket that will suite.... I have a feeling I have seen similar brackets in small led moving heads, can any one identify what standard they are? ... where would I source them? Auction fixture link See 2nd image (shows rear of fixture) all help and advice appreciated
