Rough service light bulbs like this one have multiple support filaments to prevent premature burnout from the constant movement and vibration encountered in commercial and industrial applications. The Satco S3970 frosted A19 bulb is equipped with a heavy-duty 130 volt filament, allowing it to last longer when operated at 120 volts.

Note: When used on a 120 Volt line Lumen output will decrease by 20-30 percent.
