Considerations When Replacing Bayonet Pin Bulbs
[ad#block] I have just moved into a new home, which I am renting and tried to change the lampshade on the ceiling light.

• After unscrewing the mound, and replacing the lampshade, I tried to fit the bulb again. The original bulb was a Phillips bayonet style energy efficient bulb (NB 2 pin bayonet fitting)
• It did not fit into the socket easily; the original bulb ended up shattering. I then attempted to fit a standard 40w bayonet bulb. Again, I have experienced the same problem – the bulb does not seem to fit securely in the mound. Once the bulb is set into the bayonet fixture, it will not lock into place.
• I do not think this is a wiring issue – the new bayonet bulb does work if I hold it securely in place, but when I let go, the circuit appears to break.

Do you think I need to get a new fitting in the ceiling light itself, or is it simply an issue of not fastening the bulb correctly?

Many thanks,
John

Replacing Bayonet Pin Bulb

INSTRUCTIONS

1. There are a few different pin configurations and types of lamps that use the bayonet style lamp.
2. It could be that the replacement lamp is the wrong size or type.
3. The new pin configurations are designed to prevent higher watt lamps from being used, and to save energy.
