175 Watt MH Quad 10 uF Microfarad 400 Volt VAC 50/60hHz Dry Film CAP
When a metal halide ballast stops operating properly, it's the capacitor 90% of the time, especially when the bulb is firing intermittently. So before you invest in a new MH ballast kit, you may want to consider trying a new hid capacitor first or a metal halide igniter.
