Running compact fluorescents in a 347V system? This ballast is built for it.
Designed for demanding commercial and industrial installs, this program start ballast delivers smooth lamp ignition, extended lamp life, and quiet operation — even when temps drop to -30°C. It supports a range of PL, 2D, and TTL lamps, and keeps energy waste low with high power factor and low THD.
Thermally protected. Cold-start ready. Retrofit friendly. Just plug in and let it do the work.
✅ You need this if:
-
You’re lighting commercial or industrial spaces on a 347V system
-
You’re working with CFLs like PL42, PL26, PL40, or 2D lamps
-
You want controlled starts to extend lamp life
-
You need a ballast that handles low temps, high ceilings, and long hours
-
You care about efficiency, power factor >0.97, and long-term reliability
❌ You don’t need this if:
-
You’re running T5, T8, or LED fixtures — this is for CFLs only
-
Your system isn’t 347V
-
You need instant start for short-cycle lighting (this is program start)
-
You’re planning to test and return it — installed = final sale
