Frequently Asked Questions

What is the difference between the ICN-2S39-N and the ICN-2S39-T?

The primary difference is the physical enclosure dimensions. The "-N" version features a compact 9.5-inch case with standard lead wires, while the "-T" version utilizes a longer 14-inch to 16.7-inch case style. Both operate the same F39T5/HO lamps.

Is this ballast suitable for use with motion sensors?

Yes. Because the ICN-2S39-N utilizes a Programmed Rapid Start method, it carefully preheats the lamp cathodes before applying full voltage. This protects the lamps from degradation caused by the frequent on/off cycles associated with occupancy and motion sensors.

Can this ballast be used outdoors?

Yes, it is rated as suitable for outdoor use. However, the ballast itself must be housed inside an appropriate waterproof or weather-resistant light fixture.
