i remixed this to incorporate the led lamp kit as i had multiple, the body of the box is deeper, with a cut out for the cord. Aswell a diffuser to help broadcast the light better from the lamp kit. 

To assemble unscrew the top of the led light remove the thin cover plate and replace with the diffuser. glue the other end on.. place into box and route cord out of the hole. place lid on box and your done.
