so I have a 6" Altman Fresnel which is burning through gel like crazy. we're running a show now, and every 3 shows i need to change it. its twofered, and the other insturment never needs to be changed, but this one keeps burning through. always in the same place too. ive saved every peice, and the gel is in the exact same place, same size. i changed lamps, and that did nothing though. does anyone know what it may be?
