In Germany they sell these LED Panels, though not with the same dimensions used for their curtain installations. But unfortunately it looks like they are discontinuing these products. I just searched for "LED Panel" on their website and all listings say "Letzte Chance! Nur noch kurze Zeit erhältlich." (Last chance! Still available for a short time only).
