How to have juice for sconces, without wires?

[phil59]

One of my children, who bought a house 2 months ago, where everything is already well done, bought 2 wall lights, to put next to a mirror.

Only, there is no juice nearby, and no desire to make "holes" to pass electrical wires.

So, as the base is almost square, I think we could fit 6 18650 batteries, bms, and get 12V out, but in E14, on the support, and it would be a shame to put it in E27.

I found bulbs, not pretty in E27, 12V, but not at all in E14.

The idea is to keep a shape like light bulbs, a little "twisted, tapering on the top", but I can't find it.
The goal is not to see extraordinary lighting, but to have it lit.

With 6 18650 batteries, I will do a test with my old 18650s, before taking new ones, but with that, I don't think we can count on a maximum of 50Wh, maybe 8-10H with 3-5W .

Do you have sites on which we can find E14, between 12-24V, with nice shape?

Otherwise, I will keep the 220V; 25W, with a mini 12-220V converter, to see if the base will be thick enough to hide that, but there, with the losses, it would be at the max, I think, a good hour on, so uncool ...

Or keep the old 220V, open it, and put a led inside, 2W-3W? in 12V...

You still want to enrich the Chinese market.
A wiring under molding well done is clean.

No, everything has been redone, including old-fashioned moldings, it's not to do "mischief" again.

It's also a big old-fashioned house, 200-300m from my house, which was built, I think around 1900-1950 at the max of the max.
And we won't pass the wires from the outside either, even if it's possible.

And why not induction?

If the wall is not too thick it is possible!

Brick wall of 35-45 cm, more dubbing, more placo, for induction, in any case, should not feed the outside wall ....

2 children in the village, 700m and 200-300m away, it's hell!

My wife was sulking because they didn't come by often enough now, because they come by too much!!!!

And when they are 2 days without passing, well, "she brays" (cries in the local patois).

I have all the gear to do a test,

And I have 18650, not at the top, but to do a test, it will be fine, I will do a test at 220V, with a 220V 3W led ....

It's a shame to go through 220v. See anyway the performance of DC / AC converters.
There is E14 in 12v, not twisted but a small sacrifice on the aesthetics to simplify the technique is perhaps valid:

Thank you, not the wanted top, but a realistic possibility, to stay within 12V.

It's encouraging to continue research, because there, I was drying up, I had found nothing on ALI ....

I don't know if they want to keep that tp there, the good old "yellow", or want more cool white.

So a real possibility to do something.
