Features 12" flexible arm, 3 conductor cord set, 250W ceramic heater and protective screen. Ceramic heaters that change color from coral to gray when energized. Nickel-chromium resistance wire embedded into a ceramic casting provides uniform heat transmission, 96% thermal efficiency with low element surface temperature. Inner body of the element is filled with ceramic fiber insulation, which conserves energy, maximizes efficiency and minimizes heat build-up at the terminal area. Heat up time is 3 - 9 minutes to reach 90 degrees of maximum temperature.
