Aaron Rabin Posted April 14, 2005 Share Posted April 14, 2005 Hi Everyone, Just asking for cheap, efficient solutions on how to protect an HMI in the rain. In particular, the set up includes an HMI coming through a second story window. Thanks for your time, Aaron Link to comment Share on other sites More sharing options...
Premium Member Kevin Zanit Posted April 14, 2005 Premium Member Share Posted April 14, 2005 There are a few solutions. The one I like is using a material called Celo Flex to tent the head (and cover the ballast & distro with visqueen). (http://store.yahoo.com/cinemasupplies/celoflex48x50.html) You could also make a tent over the unit with black wrap that is grip clipped to the yoke of the unit. You could also take a 4x4 frame of diffusion and tent the unit so the water runs away. With either of these scenarios I would use heat shield over the lens so that any stray water can?t touch the lens and cause it to explode.

oscar jimenez Posted April 14, 2005 Share Posted April 14, 2005 I've seen Arri HMIs take a pretty hard load of rain a few times without any "additional cover" or protection, never failed. Use and umbrella over lamp, mostly protecting glass ( lenses and lamp lens) make sure conector is covered with plastic and you will certainly need to place ballast on an apple box and cover it with plastic, as well as ballast ac plug ( even if it is stage pin connector). Ive seen Arris in open rain without an umbrella and still working under several gallons of rain, as long as the lamp is turned on it will evaporate water con contact.

J. Lamar King IMPOSTOR Posted April 14, 2005 Share Posted April 14, 2005 I second Kevin, the Celoflex works well. I have a couple of huge 4x umbrellas that I like to use if it is a downpour. A big umbrella or filter frame allows you to keep it clear of the light so it doesn't melt. Cover your distro connectors with viqueen and prop them up to keep them out of pooled water.

Premium Member Brad Grimmett Posted April 14, 2005 Premium Member Share Posted April 14, 2005 There is a gaffer in FL that makes rain covers for lights. They're called "Rob's Rain Hat's" I believe. I can't find his # at the moment, but his name is Rob Scott. You might be able to find it online somewhere. I'm not sure what he makes them out of, but I've seen them in service many times and they work great. Link to comment Share on other sites More sharing options...
