I need backlighting for my students with CVI so much of the time. I was frustrated by the cumbersome American Printing House lightbox for certain adaptations to the curriculum. I just ordered one of these very thin light boxes for my students from Amazon. This one is just great. The “plug in” one is $39.99 but you are tied to a computer USB port or plugged in the wall. The rechargeable version is $79.99 and has the benefit of portability. It is extremely lightweight. I so appreciate light weight as I travel to multiple schools! Image the ability to take this everywhere in the community to support visual skills!
