Review on 🌈 Neewer Transparent Color Correction Gel Light Filter for Photo Studio Strobe Flash LED Light - 18 Sheet Pack (12x8.5 inches/30x20 centimeters) with 9 Colors: Red Blue Pink Cyan Purple Orange Green Yellow Black by Johnathan Hegie

, I bought these to use with my newer studio flashes. I have a standard parabolic reflector that mounts via a Bowens mounting adapter and I simply glued the sheet to the front of the reflector. After just a few shots at say 75% power, the gel sheet showed signs of melting in the center of the sheet. It was a good 5 inches from the flash element, but it was already deformed. Not sure if it's because of the thickness (they're really thick - more like thin plastic wrap than the flimsy cellophane they use for flash). The color effect is good and there are many usable shades in the set - only the melting problem keeps me from recommending this item for studio flashes. I'm wondering if it wouldn't be better to use a longer makeshift nozzle (rolled cardboard?) to solve this melting problem.
