How to use the demo Lenses can be changed by removing the screw at the center of the optic. This demo is most effective when in a darkened room and the demo is on the floor shining up against the ceiling. If this isn’t feasible, shining the demo against a bare wall with the demo 10-15 ft away from the wall best replicates how the system will look in an application and the different light patterns of the various optics.
