- Identify the socket first - a bayonet socket has smooth walls with two L-shaped slots. A screw socket has a continuous thread. Take the old bulb out and look at its cap.
- Confirm the voltage with us before ordering - bayonet fittings appear on both mains and low voltage systems and the two do not interchange. Send a photograph of the fixture and the old bulb if you are unsure.
- Push and twist a quarter turn - the two side studs lock into the slots. Do not force it.
- Expect candlelight, not warm white - 2400K is noticeably warmer than a standard 2700K bulb.
- Treat 200 lumens as decorative - plan the working light separately.
- Order the whole fixture at once so every bulb matches.
A bayonet base, not a screw
This bulb uses a bayonet fitting: two pins on the side of the cap that push in and twist a quarter turn to lock. It is not an E12 or E26 screw base and the two do not interchange.
Bayonet caps appear on specific decorative fixtures, on marine and vehicle fittings, and on some imported lamps. If your fixture has a smooth socket with two slots rather than a thread, this is what it takes.

Identify the socket before ordering

Take the old bulb out and look at its cap. A bayonet cap has two small studs on the sides; a screw cap has a continuous thread. It is a two second check that saves a return.
Confirm the voltage with us before ordering
Bayonet fittings appear on both mains and low voltage systems, and the two are not interchangeable. If you are not certain what your fixture runs on, send us a photograph of the fixture and the old bulb and we will confirm before you buy.
2400K is candlelight
Warmer than standard 2700K and noticeably so. At CRI 90 the colour still reads correctly under it, which is unusual at this temperature. It suits a fixture meant to look like it holds a flame.
