Good lighting conditions are essential for precise and safe working with the sewing machine. Prym light bulbs provide a bright and pleasant warm white light for working thanks to their 15 watts of power. They make several hours of fatigue-free work on the sewing machine possible. Prym offers replacement bulbs for different models with screw or bayonet mounts. In the event that the light bulb in the machine should suddenly stop working, these special bulbs should not be missing from any sewing station.
