I have 3 of these. They are around 16" X 16" X 4" deep. Nice, light weight light boxes that have 2 circular bulbs within. These boxes are good for smaller pcs, minis,102's,113's,etc...however, I have shown it with some larger pcs on it. I very much recommend that if you want to put bigger pcs on this, you put in a clear lexan support bar or two under the white diffuser panel as the diffuser panel is supported at the edges only. Bulbs are typical residence kelvin temp bulbs and are not 5000K. The grid woodwork you see can be removed from diffuser if you wanted. I am leaving it as-is and will let you decide if you want to remove it. Box opens easily by removing 4 screws so you can change bulbs, add panel support, etc... $35 each delivered to Springfield. If you are not coming, then shipping will factor in. First email to me. Take 1 or take all.BTW, insulators not included!
