Can anyone help sourcing this electrical fitting?

[Nick67GT]

This is originally from an item bought in the USA and is rated for 110v.

The thread for the lamp is slightly smaller than an SES, so I’m thinking a low wattage ‘pigmy’ type would also do the trick.

The metal ‘springs’ at the side are just to retain the lamp holder in the ornament.

Any suggestions would be appreciated.

You wont believe it but the dustbin men took four of these away this morning!!!! They were out of four china houses my wife brought home from her sisters to sell for her animal charity fundraising. All the houses were damaged so we threw them in the bin at the weekend.

Could try these for an alternative solution https://lampspares.co.uk/

Just my luck .

Plus that’s the exact application it’s needed for…..

Don’t fancy chasing the bin lorry do you?

I'd just use 'em.

7.5W bulb at 240 volts is still 7.5W . . . and will pull less current on 240V than it would have done on 110V.

However, I will add I'm a mechanical engineer, so if any electrical engineer wants to chime in . . .

Is the fitting damaged or is it that you cannot source a bulb that is smaller than SES?
Edison screw bulbs come in common sizes, E40, E27, E14, E12, E10 and E5
also bar steward ized sizes of 39, 26, 17, 11 and maybe others

That probably summarises the problem exactly. An SES is too large, but I don’t have a smaller type to identify the thread / size more accurately.

The fitting itself is not damaged.

I suppose a UK mains rated lamp will suffice?

if you look on ebay at ses bulb holder theres a few that look like they would do if you can make up your own leg bits

ah - sounds like an E12 then - https://www.mygreenlighting.co.uk/replacement_bulbs/pygmy_and_other_small_bulbs/e12_ces/12608.html

Edit - check diameter of the thread - SES is E14 = 14mm E12 - 12mm

Ask that bloke scouring the rubbish dump for his Bitcoin hard drive to keep a look out.

Is it the same bulb holder as is often found on some Singer electric sewing machines ?

double the volts, doubles the current, 4 times the power, 7.5w at 110v is 30w at 220v.

half the volts quarter the power.

Looks very similar.

I’m going to try a local old school hardware shop as well to see what he can come up with.

A 7.5W 110V bulb and a 7.5W 240V bulb are both a 7.5W bulb - and a 7.5W 240V bulb on 240V in the UK will pull less current than a 110V 7.5W on 110V in its homeland.

I assumed a 110v bulb plugged into 240v.... of course you are correct.

ONLY true in theoretical and linear resistive circuits,
in the real world the resistance of the bulb is dependent on the temperature of the filament which varies with voltage

There is a part of the statement missing.. you should add, " With respect to the voltage " . As the number of coulombs of electrons ( the heating effect ) passing through the circuit is quite different for each voltage .
