Advance 71A8271001D – Frequently Asked Questions

1) What comes in the kit, and do I need a separate capacitor?
It's a quad kit, meaning the core-and-coil ballast plus the 35 MFD capacitor sized for this circuit. If you're replacing a kit piecemeal, the capacitor value to match is 35 MFD; a mismatched microfarad rating will pull the lamp off its rated operating point.
2) Will this magnetic ballast fit inside my existing pole-top or wall-pack ballast tray?
The core and coil measures 4.75 x 4.25 x 3.5 inches and weighs 12.5 pounds. Check the tray clearance against those three numbers before ordering, and confirm the mounting tray or housing is rated for the weight, which is typical for a 250W magnetic core-and-coil.
3) Can I dim this magnetic HID ballast with a standard dimmer?
No. The Advance 250W HPS magnetic ballast is not dimmable. For step-dimming or controlled area lighting you need an electronic HID ballast rated for dimming or a different fixture platform. Switching it on a dimmer will not control output and risks the gear.
4) What does pulse start mean on an HPS ballast, and is it different from probe start?
Pulse start uses a high-voltage igniter pulse to strike the arc rather than a probe electrode, which is standard practice for high pressure sodium. It gives more dependable ignition on cold starts and restrikes. Probe start is a metal halide arrangement, so a probe start MH ballast is not a substitute here.
5) Does this ballast meet the safety listings my facility inspector will ask for?
It is UL recognized and CSA certificated, and RoHS compliant. Thermal protection is Class P, the built-in cutout that opens on overtemperature, which is what most commercial fixture specs call for on an enclosed magnetic HID ballast. Built in the USA.
6) I'm standardizing ballast stock for a parking lot and warehouse retrofit. Is one part number enough?
For 250W HPS fixtures, yes, provided the lamps are S50. The quad-voltage taps mean one shelf item covers 120, 208, 240 and 277V fixtures across a site, which cuts the number of SKUs a maintenance crew has to carry. Order the Advance 71A8271001D and specify the tap at each fixture.
7) How much current will a 250W HPS ballast draw on my lighting circuit?
Power factor is 0.9, so it's a high power factor ballast and draws close to the lamp's real power rather than the inflated current of a normal power factor unit. For panel loading, plan on the 250W lamp load plus ballast losses at 0.9 PF on whichever tap you use, 120 through 277V.
