Many years ago I made my wife a light box for use while doing art rather cumbersome with a 60 watt globe inside it was dumped when we moved house long ago. Since then I've used card and carbon paper to copy bulkheads, deck and cabin shapes.
While browsing ebay I found this LED light pad A3 size with 3 light settings.
