Well I must say this video did give me one way I never thought of before. The lamp in the cooler with lexan or Plexiglas over the top. I've used the computer monitor and window before, and they work pretty well. But after that I bought a 16 inch X 20 inch ( Size I think ), LED light pad with 3 brightness settings, off eBay for under 40 bucks, two years ago, I'll never go back.... it work wonderfully !
Very similar to this, if not the exact same 19 inch one here.. Link:

I hope this helps others, along with the video you posted above.
