I digitized the 35mm slide film using the Neewer Advanced 2.4G 480 LED Video Light($75.49. CRI:≥96)(I bought it for a hobby earlier this year) and Perspex Spectrum Opal 1TL2 Acrylic Plastic Sheet, and I was very satisfied.
I also have a Kaiser Slimlite Plano lightbox(10.5 x 15.5"). However, I had to shoot with a slow shutter speed of close to 1 second.
