I am having problems with gel burning out unusually fast in my Altman Sky Cyc fixtures. After using them for one rehearsal and one show I'm already finding the gel fading in the center, I'm just using standard Roscolux colors. All the fixtures have 1000w lamps in them (we had been using some 1500w but they were burning even faster so I stopped using those). I can't really think of any reason why they would burn out so quickly, except for that we use them at probably have the recommended distance from the cyclorama. Can anyone suggest something that might alleviate this problem? I was browsing Rosco's thermal shield products but I don't think they could be used in the same frame as the gel with no air space between. Does anyone know of another brand of gel that is more heat resistant? Thanks!
