High Intensity Discharge (HID) lamps require a ballast to apply starting voltage to the lamp and establish current flow an arc between the lamp electrodes. Without a ballast, the arc will extinguish or draw increasing current until some circuit element burns up. Ballasts provide system stability by limiting the current that can be drawn.
F-Can ballasts are used primarily for indoor downlighting applications where quiet operation is essential. All the components of these ballasts are enclosed in a fluorescent-style ballast can and are thermally protected.
Universal Ballast 11210506CTC, Replacement F-Can HID Ballast Kit for 70 Watt Metal Halide. This F-Can HID Ballast is designed with a Circuit Type HX-HPF, for one 70W Metal Halide Lamp Type, M98 ANSI Ballast Type, 90 Input Watts, 120/277 Input Voltage, 60 Hz. The maximum distance this F Can ballast can be mounted from your 70 watt metal halide bulb is 20 feet. It has a sound rating of B and is UL Listed and CSA Certified. The physical dimensions of this F-Can ballast are 11.75" overall length, 10.56" case length and 11.14" mounting dimensions.
A ballast, like any other electrical device, generates heat during normal operation. Excessive temperature will have an adverse effect on ballast life. Normal temperature limits for Universal F-Can Ballasts have a maximum case temperature of 90°C. For proper installation, insure that remote ballasts are properly vented and mounted to a heat-dissipating surface. Ballasts in metallic casings must always be grounded.
