We're using a 12VDC, 1.5A transformer and it seems to be alright. When connected, the voltage is ~11.2V, so the transformer is slightly overloaded, but probably alright. It gets a little warmer than I'd like, but again, it seems to be fine. I should also note that we are only using 7 lights. One of the supplied lights was bad.

As for a box, we didn't use one. I just put together a quick and dirty setup. I just duct taped the lights and inverters to the provided plastic sheet. It does get warm after a few minutes, so if it were in a box, I might be concerned about it.
