Ya can't get much cheaper than this for amy shop light box. I got the 4' x 4' box, complete with bulbs for $10.00 from a Media Play store going out of business. The shelves are 1/2" bullet resistant Lexan I got (in 4' x 4 sheets') from an airport security upgrade project for $0.00 (Free!!). The 2" x 6" clear fir wood frame is a freebee that a millwork installer had left over on a Dentist office renovation. I had to cough up $20 bucks to Home Depot for the shelf brackets and plug cord. A couple of hours labor & the $30.00 for material gave me a nice Shop Light Box. Sad that most of the items it took to make it get tossed in dumpsters every day!
