Do these litle lights need a "starter"?

Just as an aside, do these little shaving light fittings just pull out like the (larger) ceiling jobs?
I break things, you see, so don't want to pull too hard...

Not always, the older ones sometimes just the inner diffuser needs taking out to replace the lamp usually a G4 capsule lamp.
I do recall some have small screws behind that diffuser that hold the whole thing in but do you need to remove the whole thing
Some though are like these and will push in and pull out the housing

But still sleeping on the sofa - the bedroom has a dismantled motorbike in it.SingleEither you're single or sleeping on the sofa!!
So I've replaced all the ceiling spotlights with little LED units too, but one of them was flickering - I swapped bulbs between 2 units, but the flicker remained, so I assume the power supply is dodgy.
I've tried searching for these on Screwfix etc, but mustn't be using the correct search term, as nothing comes up... help please?

Woo hoo! Thanks... such wonderful people here.

Quite right, turns out the middle bit with the glass levers out. Sorted
Hhmmm. Now I've examined the existing units, and they appear to be simple transformers - something like these...
Please don't tell me I need to change all ten of them for these "constant voltage drivers" because I'm using LEDs now instead of halogens
I mean, the rest of them seem to be working OK...
Don't panic. That is not a traditional (wire-wound) 'simple transformer'. It is an 'electronic transformer' - aka (in this case) a 'constant voltage power supply/driver'.Hhmmm.

It is a SMPS for halogen lights with an AC output of tens of kHz. Not suitable for LEDs.
This is what he needs:

Note it has an output of up to 50 watts so it would drive 10 5W LEDs. If the LEDs are say 7 watts use two of them with 5 LEDs on each.
Probably not suitable for some LEDs.
I note that not only is it an "Electronic Transformer" but it is "for LV Halogen Lamps"!
He might do. However, if I were him I would certainly be inclined to first see what happens if the existing power supplies is used to supply one or two LEDs - with the caveat that if they are cheap LED 'lamps' with just a current-limiting capacitor and a rectifier, the experiment might kill them.

Well, that's what he did do... 'cos he didn't know any better, thinking that the LED bulbs were a simple replacement for the halogen ones. I did check the voltage, and thought that was it...
So at the moment, I have I think 11 LED bulbs running off these things, and one of them flickers. Guess I've just been lucky
So... are they all going to explode some day, or am I safe...?
