I had someone ask me the other day if I ever heard of Lumitape. I hadn't so I asked him exactly what it was, because maybe it was spelled or pronounced different. He said it is applied to signage and glows at night, so you don't need electrical lighting. ??? I've seen vinyl that changes coloring at night to stand out, but I believe you still need it to be on a backlit panel (I think). He is a doctor and wants to put a sign on the side of his building but does not want to install a lightbox or channels or anything like that. If this product exists, it's news to me. Can anyone enlighten me on the subject? I'm not a big signshop, nor do I deal with anything electrical, etc. I'm primarily vinyl signs, banners, coro, and other design, so whatever help someone can give I'd appreciate it.
