ONLY 1 LEFT! note the size is 11x17, not the smaller 8.5x11... I have come into possession of a small number of these Apollo Glowpro 11x 17 light boxes. They say on the box that they are 5000K, but they all look a little different, so I think the fluorescent tubes must have been changed in some of them. Of course, you can use any tube you like, they take 15w 18" tubes. Great for photography, display, or color comparisons. See the photos, I took some with only one light box under the insulators and some with a second light box standing up behind them. These run on 110VAC, and the power cords are between 3 and 5 feet long. $55 each plus shipping.
