Reese's Logo LED Lightbox!
I use this LED strip to illuminate my lightboxes: https://www.aliexpress.us/item/3256805735110443.html

Assembly is similar to other lightboxes. Attach an LED strip to the walls of the lightbox, ideally closer to the back to help diffuse the LEDs better. Personally I use reflective aluminum tape on the back cover of the box to increase overall brightness.
