A GU24 bulb has two pins that push into the socket and twist to lock, on everyday shapes such as the A19. It doesn’t fit a screw socket, so match the base on the old bulb.
What it looks like
There’s no screw thread, just two pins on the end of the base. GE calls it “2-Pin Turn-and-Lock (GU24)”. The glass above it can look like any household bulb, so the base is the part to check.
A GU24 bulb and an E26 bulb don’t swap: if the base doesn’t match the socket, the bulb won’t work. Feit sells the same 8.8 watt A19 LED in both versions, the OM60DM/927CA/4 on E26 and the OM60DM/927CA/GU24/4 on GU24, so read the base on the box as well as the shape.
Where it’s used
Feit lists its 8.8 watt GU24 A19 for ceiling fixtures, ceiling fans, table lamps and outdoor lighting. It’s rated for damp locations, so outdoors that means a covered spot, not one open to rain. Feit’s GU24 puck light is made for under cabinets and other tight spaces.
Some bath fan lights use GU24 too: Broan-NuTone’s QT130LE takes 10 watt GU24 LEDs. See bathroom fan light bulbs.

In order: Feit OM60DM/927CA/GU24/4, A100DM827GU24/10KLED, PU60/830/LED/GU24, BPESL13T/GU24 and BPESL23TM/GU24, GE Ultra Bright LED 150 Watt Replacement A21, and Westinghouse 9.8OMNIA19/LED/DIM/SW/GU24/27 and 8R30/LED/DIM/FL/GU24/27.
The Feit GU24 LEDs above are dimmable, and its GU24 CFLs aren’t. Feit lists all five as damp rated and rated for enclosed fixtures. Westinghouse lists its 9.8 watt A19 for totally enclosed fixtures but not its 8 watt R30.
What it’s confused with
- GU10. Its pins twist to lock as well, but it’s the 120 volt spotlight base, found on small reflectors such as the MR16.
- E26. The standard US screw base, on the same A19 shape. It needs a screw socket.
Switch the light off and let the bulb cool before you twist it out.
