All EZ Mount LED Ring Light Mount Directly to a Camera Lens The EZ Mount LED Ring Light can be quickly and easily adapted to any vision system with either of four standard mounting options. First, there is a standard M46 thread protruding from the back of the EZ Mount LED Ring Light. Using readily available step-up or step-down rings it can be mounted directly to the threads found on the front end of most lenses. Second is the ability to mount the lens at the front end of the EZ Mount LED Ring Light. Once again, an off-the-shelf step up or step down adapter ring can be used to adapt lenses with M43 or smaller filter mounting threads. A flange at the front end of the EZ Mount LED Ring Light holds the step ring with three set screws, and the camera lens is inserted through the center of the EZ Mount LED Ring Light and threaded onto the step ring. In those few cases where the lens's locking thumbscrews may prevent the lens from fitting through the center of the EZ Mount LED Ring Light, extra low-profile replacement set screws are included, allowing the protruding thumbscrews to be removed. Step up and Step down adapter rings are not included with the light. Third is a T-slot on all sides. Standard industrial T-nuts can be dropped into the slot for mounting. Fourth way to mount the light is using the threaded M4 holes on the back plate of light. The EZ Mount LED Ring Light are a high output LED light in an aluminum housing.
