Philips Lighting 913700503051 – Frequently Asked Questions

1) Will the Philips 913700503051 HID ballast run a 175W metal halide lamp in my existing pole fixture?
It's built for a single 175W metal halide lamp carrying ANSI code M137-M152, one lamp per unit, with a ballast factor of 1 so the lamp runs at its rated output. Check the ANSI code stamped on the lamp you are replacing: if it reads M137 through M152 at 175W, this is the right magnetic ballast. It will not run high pressure sodium or any other wattage.
2) Can this ballast be mounted remotely, away from the light fixture?
Remote wiring is allowed, but only to a maximum of 2 feet between ballast and lamp. That covers a ballast tray in the pole head or a separate compartment in the housing; it will not support running the ballast down at the pole base or into a nearby enclosure. Factory leads are 12 inches of stranded wire.
3) Is a SUPER-CWA ballast the right choice, or should I use a reactor or HX type for 175W metal halide?
SUPER-CWA is a constant wattage autotransformer circuit, which holds lamp wattage within 10 percent through line voltage swings and gives you the 0.9 power factor and the multi-tap flexibility. That is what you want on outdoor area and site lighting where incoming voltage is not tight. Reactor and HX types are simpler and cheaper but tolerate far less line variation and are limited to specific input voltages, so they suit indoor circuits with stable power.
4) Can this Philips HID ballast be used outdoors in a wet-location pole fixture?
It is suitable for outdoor use and is UL Recognized as a component, with UL Insulation Class H at 180 C and a 1029C UL temperature code. Being a Recognized component, it is intended to be installed inside a fixture enclosure that provides the weather protection, not mounted in the open.
5) Will this ballast restrike the lamp automatically after a power blip?
No. Automatic restart is not a feature of this ballast, so after an outage the metal halide lamp has to cool before it will reignite, typically several minutes of dark. On sites that need instant light after a dip, pair the fixtures with a quartz restrike fixture or keep an emergency source on the area.
6) What is the open circuit voltage on this 175W MH ballast, and why does it matter for troubleshooting?
Open circuit voltage is 275 V nominal, with an acceptable test window of 250 to 300 V. Secondary short circuit current runs 1.6 to 1.95 A. If you meter the secondary with no lamp in and read outside 250-300 V, the ballast is suspect rather than the lamp.
7) What is the base model number behind the Philips 913700503051 core and coil HID ballast?
The base model is 71A5593, and it is catalogued for ordering as CORE & COIL HID 71A5593001D. Distributors cross-referencing older paperwork will usually find the 71A5593 designation on the ballast label.
