Rectangular metal HID ballast kit, grey finish, labelled 250 W 1 lamp 120 277 V

Philips

Philips Advance 250 W 1-Lamp HID Ballast Kit 71A5771-001D

SKU CH-TXPH-BW5FB

Magnetic HID ballast kit runs one 250 W metal-halide lamp on 120/277 V AC input

  • Product typeBallasts
  • Operates one metal-halide lamp up to 250 W
  • Multi-tap 120/277 V input suits common supply voltages
  • Probe start method with ANSI M58 compliance
  • Starts reliably down to -20 °F ambient temperature
  • Magnetic ballast delivers 1.0 ballast factor at 60 Hz

Philips Advance 250 W HID Ballast Kit

This kit provides a magnetic ballast for a single 250 W metal halide lamp. It operates on dual 120/277 V AC input at 60 Hz with a 1.0 ballast factor. The unit is rated for a minimum starting temperature of -20 °F and carries ANSI code M58.

Replaces worn magnetic ballasts

Swapping a failed probe-start ballast with this kit restores proper lamp ignition and running current. The upgrade is worth it when the existing unit shows hard starting, audible humming or overheating after extended operation.

Probe-start magnetic limits

Probe-start technology requires a warm-up period before full output and restrikes take several minutes after power loss. The ballast consumes 294 W input for a 250 W lamp, so circuit capacity must accommodate the higher draw.

Questions about this item

What input voltage range does the 120/277V AC ballast require for the 250 W metal halide lamp?

The ballast operates on 120 V or 277 V AC at 60 Hz and draws 294 input watts when powering the single 250 W probe-start metal halide lamp.

Which wiring step is most often missed when installing the 71A5771-001D kit with ANSI code M58?

Connecting the 120 V or 277 V supply to the correct primary tap matching the site voltage; using the wrong tap prevents the ballast from starting the lamp at the rated -20 °F minimum temperature.

When should the 250 W probe-start ballast be replaced if the metal halide lamp flickers or fails to strike?

Replace the ballast when the lamp no longer starts reliably at -20 °F or when input power drifts far from the 294 W rating, indicating core saturation or capacitor aging.
