Philips Lighting 913700500891 – Frequently Asked Questions

1) Will the Philips 913700500891 ballast run a 70W metal halide lamp, or is it HPS only?
HPS only. The 913700500891 is built for a single 70W high pressure sodium lamp carrying ANSI code S62. A 70W metal halide lamp uses a different ANSI designation and a different ballast waveform, so it will not run correctly here. Match the S62 marking on the lamp before you wire it in.
2) Does the 70W HPS Philips core and coil ballast need a separate ignitor and capacitor?
The ignitor is built in, listed as INTEGRAL and rated to 125 C, so no separate starter module is required. The capacitor is a separate piece: it calls for a 28 MFD, 120V capacitor, Philips catalog number 7C280M12RA, rated 105 C, 1.65 in diameter by 2.75 in tall. If you are reusing the fixture's existing cap, confirm it matches that value and voltage or the lamp will not reach full output.
3) Can I mount this HPS ballast remotely from the fixture head?
Remote wiring is allowed, but the run is short: 2 feet maximum from ballast to lamp. That covers a ballast tray in the base of a pole head or just outside the housing, not a ballast box on a wall feeding a distant fixture. The factory leads are 12 inches of stranded wire, so anything past the housing means splicing in a junction box.
4) Will this 120V ballast work on a 277V circuit?
No. This one is single voltage, 120V at 60 Hz only, with an open circuit voltage of 120 V. On a 277V feed it will fail immediately. For 277V or multi-tap service you need a different ballast in the same 70W HPS S62 family, not this model.
5) I have a ballast stamped 71A7907B in the fixture. Is the Philips 913700500891 the same thing?
Yes, 71A7907B is the base model behind the 913700500891, ordered as CORE & COIL HID 71A7907001DB. If the label in your fixture reads 71A7907, you are looking at the same 70W HPS, 120V core and coil assembly. Check that the old unit was also 120V before swapping, since the 71A79 family covers other voltages.
6) Is a 70W HPS core and coil ballast OK in an outdoor parking lot or wall pack fixture?
Yes, it is rated for outdoor use and is a common replacement in site and area lighting. The winding carries UL insulation Class H at 180 C, with the integral ignitor good to 125 C, so it tolerates the heat inside a closed HID housing. Keep the fixture gasketed; the outdoor rating applies to the ballast in a suitable enclosure, not to open exposure.
7) How much current does the Philips 913700500891 draw, and how do I size the branch circuit?
On 120V, 60 Hz it draws 0.75 A nominal at 86 W input power for a 70 W lamp. Starting current is 0.9 A, open circuit 1.3 A, and short circuit 1.9 to 2.9 A. Use the 86 W figure when you total up a pole run of heads, and remember the input wattage is higher than lamp wattage because of ballast losses.
8) What does R-HPF mean on this ballast and does it matter for my utility load?
R-HPF is a regulated high power factor circuit, and here it gives a 0.9 nominal power factor with a ballast factor of 1, meaning full rated lamp lumens. High power factor draws less line current for the same wattage than a normal power factor ballast, which matters when you are loading several heads on one 120V circuit. The regulated design also holds lamp wattage within the trapezoid as line voltage wanders.
9) Is the Philips 913700500891 UL Listed or UL Recognized?
It carries a UL Recognized mark, shown as ULR on the approval marks, with UL temperature code 1029A and temperature marking A. Recognized components are evaluated for use inside a listed fixture rather than as a standalone listed product, which is exactly how a replacement HID ballast gets installed. Hipot ratings are 2000 V for one minute and 2500 V for two seconds.
10) Does this ballast restart the lamp automatically after a power blip?
No automatic restart function is built into the 913700500891. Like any HPS core and coil, the lamp has to cool before it will restrike after an interruption, and this ballast does not include circuitry to force an immediate restart. Plan for the normal HPS cool-down on outdoor heads served by this ballast.
