  • typeBallasts
  • 250 W output powers one metal-halide lamp
  • Multi-tap 120/208/240/277 V input fits many supplies

Philips Advance 71A5770-001D 250 W HID Ballast Kit

This Philips Advance magnetic HID ballast kit operates a single metal halide lamp rated at 250 watts. It carries ANSI code M58 and supports multi-tap input voltages of 120, 208, 240 and 277 volts AC at 60 Hz. The unit is designed for new installations or direct replacements in compatible fixtures.

Multi-tap voltage limits and probe start constraints

The ballast accepts four discrete input voltages but cannot auto-range outside the listed 120, 208, 240 and 277 volt taps. Probe start ignition requires a minimum starting temperature of -20 degrees Fahrenheit. Input power draws 298 watts with a ballast factor of 1, so circuit planning must account for the higher wattage.

Replaces magnetic probe-start ballasts for 250 W

This kit replaces an existing magnetic probe-start ballast carrying the same ANSI M58 code and 250 watt rating. The upgrade is worthwhile when the old unit fails, hums audibly or shows tar leakage. It is not suitable for pulse-start lamps, electronic ballasts or fixtures wired for multiple lamps.

Questions about this item

Should I choose the 250 W kit or a different wattage for my metal halide lamp?

This kit supports one 250 W metal halide lamp with ANSI code M58; select it only if your lamp matches that wattage and ANSI code.

What does the 298 W input figure mean when the ballast is running in a real fixture?

The ballast draws 298 W from the supply while delivering 250 W to the lamp, so the fixture must handle the higher input load.

Which input voltage should I wire on the 120/208/240/277 V multi-tap for my 240 V supply?

Connect the 240 V tap; the ballast is rated for 60 Hz operation on any of the four listed voltages.
