Try some lighting company websites. I originally intended to say lighting control sites, but maybe lighting itself might have something. Maybe someone there will have been clever and provided such artwork as part of a place to click on the site, or perhaps some real on-purpose artwork might be found under some kind of customer support category.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
