I am offering two Gagne brand Porta-Trace model 1012 light boxes for displaying or photographing insulators and other transparent materials. When used in tandem you get an excellent view by base and back lighting pieces simultaneously. Each box contains two 5000K color correct lamps for accurate color representation.

One description on Amazon includes the following features:

Provide bright, even light and virtually eliminate hot spots UL listed cord and on/off switches Made of tough stainless steel frame Thick Plexiglas top Perfect for drawing, tracing, embossing, calligraphy, viewing, or presentations

The boxes measure 10 x 12 x 3". As a consequence of use, the plexiglass surfaces have shallow scratches and scuffs which are NOT visible with the lamps on. One could easily remove the four screws and flip the surface for a factory fresh condition.

I found these priced from $25.00 to 99.00 online. I am asking $45.00 plus shipping for the pair. The shipping weight is approx. 12 pounds if you would like to calculate cost to your home. If I don't get any takers for the pair, I will sell them individually for $25.00 ea. plus shipping.
