Though I haven’t been using a light box, I do have one, and am considering trying it out. I have a “Digital Concepts Portable Lighting Studio” which seems like it could do the job. It costs $59.00 on Amazon, includes two lights, a blue & gray background cloth, and some diffuser screens that can be configured with their velcro strips, and folds to 17 x 17 inches. Here are some pictures.
