Matthews Studio Equipment's Hot Flags allow precise cutting of light at relatively close distances. They are made of a patented thermal-resistant fabric that dissipates heat and weigh about half as much as metal Hi Temp flags. They come in four sizes: 18"x24", 24"x26", 48"x48" and 24"x72." MSE owner Ed Phillips and technical manager Bill Hines said they set up a 12K HMI several feet away from a metal flag and a Hot Flag, then, using an infrared temperature gauge, measured temperatures of 950° and 160° respectively, burning through the metal while leaving the Hot Flags cool to the touch.
