The LPSB is an electronic ballast that uses AC or DC from either a battery or power supply to produce high-frequency AC to start and operate lowpressure sodium lamps.

Advantages:

Eliminates the need for starters and other ballasts

Achieves high-frequency operation, eliminating audible noise

Provides much higher efficiency than standard AC ballasts

Allows operation of lamps at customized power levels lamps can be overdriven or underdriven

Eliminates 50/60 Hz flicker

Smaller in size and weight

In some cases, it is possible to arrange UL Listing for LPSB. Engineering fees for customization vary according to design needs.
