Frequently Asked Questions (FAQs)

1. How do single pin fluorescent bulbs work?

With fluorescent lights, the term "single-pin" refers to the single metallic contacts at each end of the fluorescent light tubes. Gas inside the tubes is ignited by a surge of spark that's provided by a ballast inside the light fixture. If the tubes flicker or won't come on at all, it's time to replace the ballast.

2. Can you replace old fluorescent tubes with LEDs?

Yes, you can replace fluorescent tubes with LED tubes or LED-integrated fixtures. If you just want to replace the bulbs, you can use plug-and-play, direct-wire, or hybrid LED tubes. Plug-and-play tubes are the easiest to install as they do not require any rewiring to the fixture.

3. Are fluorescent bulbs measured pin to pin?

Fluorescent tubes are measured in eighths of an inch, with the measurement being drawn from pin to pin at the end of the tube.
