Philips Lighting 913700501071 – Frequently Asked Questions

1) Will this Philips magnetic ballast run two F20T12 lamps, or can I use it on a single lamp fixture?
The Philips RL2SP20TP magnetic ballast is built for two F20T12 lamps wired in series, each rated 20 W. Series wiring means both lamps are part of one circuit, so it is intended for a two lamp fixture, not a one lamp fixture. Lamp type matters as much as count here: F20T12 only, not T8 or T5.
2) Will this F20T12 ballast fit inside my existing fluorescent fixture channel?
The metal T1 housing measures 6.5 x 2.38 x 1.5 inches. Measure the channel on the fixture you are retrofitting against those three numbers before you pull the old ballast, since T12 magnetic cans vary in length and a longer original will leave the mounting holes off.
3) Can I mount this ballast remotely, away from the lamps?
Yes. Remote, tandem, and through wiring are all permitted, with a maximum ballast to lamp distance of 30 feet in any of those configurations. That covers remote mounting in a ceiling plenum or running one ballast across tandem fixtures, as long as you stay inside 30 feet of wire run.
4) Is this a 120V only ballast, or will it run on 277V?
120 V, 60 Hz only. Nominal input current is 0.49 A and nominal input power is 36 W for the pair of 20 W lamps. If your fixture is fed 277 V, this is the wrong ballast for that circuit.
5) What does preheat start mean on this ballast, and will it work with my lamp starters?
Preheat is the starting method, with a nominal ignition time of about 1 second. Preheat circuits heat the lamp cathodes before striking the arc, which on F20T12 fixtures normally means a starter in the circuit. If your fixture is a rapid start or instant start design, a preheat ballast is not the equivalent swap.
6) Can this Philips F20T12 ballast be used in an outdoor light fixture?
It is rated suitable for outdoor use and carries a CSA certificate. The ballast itself is outdoor rated, but the fixture and enclosure still have to be the weather rated part, since the ballast sits inside a metal T1 can and is not a weatherproof enclosure on its own.
7) Is this ballast quiet enough for an office or classroom?
Hum and noise level is rated A, the quietest sound class used for magnetic fluorescent ballasts. That suits offices, classrooms, and libraries. Magnetic ballasts still hum more than electronic ones, so in a very quiet space an electronic ballast will be noticeably quieter.
8) Does this Philips ballast restart on its own after a power interruption?
Yes, automatic restart is built in, so after a power blip or a circuit being cycled the lamps re-strike without anyone resetting the fixture. Useful on stairwells, exterior fixtures, and any circuit on a timer or photocell.
9) What wire is on this ballast and how much insulation do I strip for the wire nuts?
Leads are solid conductor at 18 AWG nominal, with a specified strip length of 0.50/0.375 mm. Solid 18 AWG pairs fine with standard small wire connectors for fixture whips.
10) How does the Philips F20T12 ballast ship, one at a time or in a case?
Each pack holds one ballast, and an outer box holds 10 packs. So a full case is 10 ballasts, which is the sensible buy if you are recoating a building's worth of two lamp F20T12 fixtures.
