I'm continuing to experiment with my displays. I rebuilt these from previous backlit to underlit format. I wanted to show off the bubbles better. Also, by removing the backlit Pannel, allowed more room for an additional row --4 more LRI's !. And future (hopefully), if I want to add another column, easy to do by respacing the vertical rods. Some have said, looks like jail bars... These are so that in travel, they cannot contact each other and cause damage. I say travel, because I want a pack & play, grab & go to shows...without all set up time. I added a handle on top. The under lights are 5000K, dimmable, cabinet under lights, inexpensive. The measuring still drives me crazy, trying to get it right, measure 4 times cut 5 times...!!! It only took me about 8 hrs!!
