Model information

The application of this gadget is so versatile - you can use it anywhere. Attach it to anything using hot glue:

Knifes - so you can see what you are knifing (not legal advice)
Phones - so you can feel like a professional photographer, or at least someone with a light
Your teeth - if you have iron teeth OR a cyborg, attach a magnet to the NanoBeam™ and illuminate your next meal
Pens - study like Harry Potter (under a blanket, with dramatic flair).
Etc. - the possibilities are limited only by your imagination or local regulations.
