FAQ
White Filament ST19 Bulbs FAQs
What is an ST19 white filament bulb?
An ST19 white filament bulb is an elongated tubular LED bulb with a visible white filament — Feit Electric's patented technology. The ST19 shape is longer than a standard A19 and wider in the middle, designed for string lights, industrial pendants, and exposed-socket fixtures.
Can ST19 white filament bulbs be used in string lights?
Yes — ST19 bulbs are one of the most popular choices for outdoor and indoor string lights. The elongated shape and exposed white filament create a dramatic visual effect in string light strands, with a clean white glow instead of the traditional yellow.
Are ST19 white filament bulbs dimmable?
Yes — dimmable ST19 white filament bulbs are available from Feit Electric. Always use an LED-compatible dimmer switch. For string light applications, confirm your string light strand supports dimmable bulbs before pairing with a dimmer.
What fixtures work best with ST19 white filament bulbs?
ST19 white filament bulbs work best in string lights, bare-socket pendant lights, industrial-style cage fixtures, and any open application where the full length of the bulb is visible. They use a standard E26 base and fit any medium socket.
