Long Life Bulb! This 25 watt thread spun bulb has a satin finish that is created by spinning the bulb with a silk thread. Also known as a silk spun or a satin spun bulb. Unlike a regular flame tip bulb where the glow from the filament is visible, the resulting light from our thread spun bulb is a unique, warm, gas light type effect.
This bulb has a long life of up to 5,000 hours. Compare this to other similar bulbs that often have a maximum life of 2,500 hours.
