Q:

What are some features of a Philips Advance ballast?

A:

Quick Answer

Some features of the Phillips Advance ballast are a programmed-start design, parallel-wired circuits and less frequent lamp replacement than is necessary with instant-start, series-wired ballasts. The Phillips Advance ballast is more economical than traditional series-wired ballasts and results in substantial savings in lamp replacement costs.

Full Answer

A Phillips Advance programmed-start ballast generally provides a lamp life of 50,000 power cycles, compared to 10,000 to 15,000 power cycles provided by instant and rapid-start ballasts. The programmed-start ballast heats a lamp’s components to a precise temperature, unlike instant and rapid start ballasts, which supply a starting voltage of 500 to 600 volts and maintain this level for the duration of the power cycle. By heating the lamp’s components to a precise temperature, the programmed-start ballast puts less stress on the lamp’s electrodes and reduces the depletion rate of the lamp’s light-emitting materials, resulting in longer lamp life.

Phillips Advance ballasts also feature parallel-wired circuits as opposed to the series-wired circuits found in most instant and rapid start ballasts. When a lamp powered by a parallel-wired ballast burns out, the remaining lamps stay lit, making the burned-out lamp easy to identify and replace. As a result, Phillips Advance programmed-start, parallel-wired ballasts offer substantially reduced costs associated with bulb replacement.
