Hi all, For a production of Back to the 80s at my school, we are planning to have six 2'x2'x2' cubes that are faced with frosted plexiglass on the front and would move around the stage for various scenes. We would like to backlight the plexi as well, but the light must be wireless (i.e battery-powered) for the sake of not having wires all over the stage in such a major dance musical. Control would be local (probably just a regular switch on the back of the cube). Heat venting from a bulb would not be an issue as we are planning on leaving the back of the cube open. So basically, I need to find a way to power a light that has enough output to cause a noticeable glow on the plexiglass, and this light must be powered from batteries (no more than 18v, ideally). Will I have to use an inverter or is there another way? My budget is fairly low, but I want to consider the possibilities, so all suggestions are welcome. Thanks.
