Well we need to have in mind that a generic lamp will give you 3500 to 4500 lamp hours and the Phillips will give you 6000 to 8000 lamp hours ,The lamp itself typically uses AC current and about 15,000 volts to ignite the lamp's mercury vapor gas. The gases inside the lamp react when electricity charges up the mercury gas creating very bright light. The voltage drops to keep the flow of electricity to the lamp.
The symptom of a bad ballast is that you could hear a constant CLICKING or electrical BUZZING sound,my recomendation is to take out the lamp to physically check for any sings,(shatter fillement,black or grey spots in the fillement or smoke ) you can get good deals at http://www.discount-merchant.com/?click=52978
