Quoted from twitami:Not a display panel as in score display, but a display for showing the different types of LED bulbs and being able to compare them. Something that holds a bunch at the same time. Cointaker and other LED retailers use them at York and Allentown and other shows, and I don't think they make them--I think they buy them somewhere.
We have one for shows that does like 40 lights at once. We made it tho. Not sure where anyone would buy these
