I am looking for ideas to weatherproof some moving heads suspended from truss. I have a show coming up where I will need to have section of truss with four moving heads and a couple of other lights outdoors for 3-4 weeks.
It's triangle 2" truss, and the flat side will be facing upward.
Does anyone have any suggestions how I might weatherproof this other than throwing a tarp over it when it rains. I was thinking of a half cylinder of plexiglass attached to a board sitting on the flat portion of the truss.
Anyone ever seen something done along these lines, or have any ideas for me. What do amusement parks, etc. do in these situations?

For outdoor use it is hard to compromise quality for budget. Tempest definitely makes a good product but you will also have to pay for that product. The trick to making an enclosure for a moving light outdoors is that you are not only protecting it from rain and such getting in but you must also keep the heat from being trapped inside and not being able to get out, figuring that on top of the heat from the fixture you also have the heat from the sunlight getting trapped inside like a greenhouse. If the fixture does not have the proper ventilation you will quickly learn what happens when it goes into overtemp and hopefully it is only that the fixture shuts off. You probably could do a Google search and find some other company making a similar enclosure, maybe even offering it cheaper, but be careful you are not just shoving you fixture into what will become a plexi based coffin to bury it in. If the fixtures on your show are going to stay in place outdoors then I would highly suggest that you go with an established product so that your fixtures stay in good working order and also because most of them have a way of locking the enclosure to keep, or at least deter, someone from walking off with them. If the fixtures are not staying in place and you are removing them after every show then you could simply construct a shield or flat cover that could mount a short distance away from the fixture and block it from the sun and rain.

This http://www.martin.com/product/product.asp?product=rainmac is designed to be positioned between the truss and a moving head. But it's not for strong winds. It'll only keep water from dripping down onto the fixture. An alternative to tempest products is to bring the truss in every night and wrap the fixtures in heavy duty garbage bags after they have cooled. It won't do anything for them when they're in the air, but it will protect them when not in use.
