This one is even better :rotfl::rotfl::rotfl::rotfl::rotfl:

Right then, there are bayonette fittings and small bayonette, there are also edison screw and small eddison screw fittings all of which are commonly found in table lamps.

The ceiling version you are describing is a compact fluorescent or PL type which will be either a 2 pin fitting or 4 pin fitting there is no 3 pin fitting - never has been that I am aware of and ive been a sparky over 20 years.

Sorry but had to laugh.

The laugh is on you.

They are called BC3 Base Lamps or Bulbs. and have been around for many years.

BC3 base lamps are identical to other energy saving compact fluorescent bulbs except it has three pins at the base instead of the usual two (see figure 2 above). They are installed in some new properties to prevent the occupier from reverting to the old incandescent bulbs. Unfortunately, because of the new design and the fact that they do not enjoy the subsidies that other energy saving bulbs receive, they are far more expensive to buy. With this in mind we have kept our margins to an absolute minimum on sales of these lamps.

You might be needing some of these Mr Sparky.

It's 'bayonet', not 'bayonette' !

He hasn't been back to thank you for that.

I think he is delicately referring to the lampholder socket by using the feminine noun. The lamp itself will still be bayonet.

The domestic bayonet is BC 22 also known as B22d or Ba22d. There is a 3 pin variant - B22d-3 apparently used on the railways maybe to discourage filching or maybe to assist with inventory management to avoid confusion between bulbs rated for rolling stock use and bulbs rated for use in buildings. Whether this B22d-3 is the same as the domestic variant I am not sure

Hello,

Just wondering if any of you kind folk with electrical appliance knowledge could help me out here!

Lightbulbs in two of my table lamps went pop so I duly bought a couple of replacement bulbs.

When I tried to fit them, for some reason, they wouldn't slide iinto place as they would normally. They sort of sat on top of the fitment but wouldn't slide into the grooves to secure the bulb. I didn't want to apply too much pressure in case they shattered but it was as if I couldn't push the bulb down far enough to twist into place. (Hope this makes sense!) Both lamps are standard bayonet bulbs not screw ins.

Anyone know why this is and is there anything I can do about it? Loathe to consign them to the bin!

Did the same myself the other day - but the bulbs that wouldn't fit had just come out so I knew they should fit - only took them out to clean the fitting - I gave up (didn't want to break them) and my wife just plugged them in easy peasy

Just give them to someone else to fit who's not afraid to push harder

I have twice had occasions recently when the bulbs on my table lamps have blown. On taking the bulb out, the bit at the base with the prongs on has sheared off and been left in the lamp, with only the bulb and half the metal bit at the base coming away. The first time, I did not realise and tried to put another bulb in, bot obviously it wouldnt 'push home' as there was the remains of the other bulb still there - if that makes sense. I had to use a pair of needlenose pliers to grasp and remove the offending bit of the old lightbulb (after unplugging it first of course!).

Could this be your problem?

I have had the same this week with two bulbs from a 3 bulb ceiling light but they were Edison screw in bulbs.

Well ya live n learn - never seen em in all my days as a sparky, even when doing domestic stuff. So I stand corrected silly me
