Advance ISB043214EI – Frequently Asked Questions

1) Will the Advance ISB043214EI run fewer than 4 T12 HO lamps, or does it need all four?
The ISB043214EI is a 1-to-4 lamp sign ballast for T12 high output lamps, so it will run one, two, three, or four lamps. That flexibility is normal on instant start sign ballasts and it is what lets one part number cover a range of cabinet lengths. It is a fixed output ballast, so there is no dimming or step control.
2) Can I use the Advance sign ballast on both 120V and 277V without ordering a different part?
One part covers it. The ISB043214EI accepts 120 through 277 volts, 50 to 60 Hz, so the same ballast works on a 120V retail storefront circuit and on a 277V commercial lighting panel. Wire it to whichever supply the sign is fed from, no voltage-specific model to pick.
3) Will this Advance ballast fit inside my sign cabinet raceway?
Case dimensions are 14.31 inches long, 3.19 inches wide and 2.63 inches high, and it weighs 9.96 pounds. Measure your raceway depth against the 2.63 inch height and leave room at the ends for conductor entry and a service loop. The near-10-pound weight matters on a pole sign or a remote-mount box, so fasten it to structure, not just to a sheet metal back panel.
4) Is this the right ballast for T8 or T12 rapid start lamps?
No. The ISB043214EI is built for T12 high output lamps only, and it is an instant start ballast. T12 HO lamps use recessed double contact sockets rather than the bipin sockets on standard T8 or T12 lamps, so the lamps are not interchangeable in the fixture either. If your sign carries standard T8 lamps or rapid start HO lamps, you need a different ballast type.
5) Does this Advance sign ballast carry UL and CSA listings for a permanent outdoor sign install?
It holds both a UL certificate and a CSA certificate, and it is RoHS compliant. That covers the AHJ question on US and Canadian jobs. The ballast itself is not weather rated on its own, so it still has to live inside the sign cabinet or a suitable enclosure.
6) What does the 0.98 power factor mean for sizing the circuit on a multi-tenant sign?
A 0.98 power factor is high power factor, meaning nearly all the current drawn does useful work. For a property manager or electrician loading several tenant signs onto one 120-277V circuit, that keeps line current close to the real wattage instead of inflating it, so you fit more ballasts per breaker than you would with a low power factor magnetic unit.
7) Do the lamps in my sign light instantly in cold weather with this ballast?
It is an instant start ballast, so lamps strike immediately with no cathode preheat delay. That is what you want on a sign that switches with a photocell or timer. Keep in mind instant start is harder on lamp cathodes where the sign cycles on and off frequently, so it suits dusk-to-dawn sign duty better than rapid switching.
8) Is the Advance ISB043214EI made in the USA for a Buy American sign job?
Country of origin is the USA on the ISB043214EI. If your specification calls for domestic manufacture on a government or institutional sign project, that is the documentation point to cite, along with its UL and CSA certificates.
