I'm in the process of building a simple bank of BL bulbs. I'm keeping the construction really simple, just laying everything out on a 24x24 wood panel. On each of the four corners of the panel I'm attaching simple legs made up of cut pieces of wood. Then I just turn the whole thing over and let it rest on the floor and cover it with black plastic. Who needs a box anyway?
True that would be sufficient. But If i am going to the bother I want it to be a little more complete.
