Enclosure ideas? Studio Spot 575

Just picked up 6 Studio 575's for our residential xmas light show.  I need to obviously protect them from the elements.  I can't seem to find what the best thing would be for an enclosure (noobie here...).  Found some sharpy domes but they are too small.  Any ideas for a small scale residential display?  Used equipment is perfect since we aren't a large scale operation here. TIA
