I'm looking for several small pattern projectors. Beam distance is only about 8' and the beam field is only 24" wide (the surface of a bar). Problem is the only place to mount them is on top of a wooden ledge which is only 6" deep. I can screw them onto the ledge, but they won't be permanent. I was considering the Altman Micro Ellipse, but even that might be too big, although I can't find specs on their website. No hurry as this isn't going in until February. Suggestions?
