Light switch wiring - help appreciated

It's more likely to be due to the dimmer being an older model designed to work with incandescent lamps (note the 210 W rating). As LED lamps will produce light at much lower power levels than incandescent lamps older dimmers may not be able to produce sufficiently low power levels to properly dim LED lights.

You also need LED lamps that are dimmable. (Not all of them are.) I have some but they won't dim smoothly all the way to black with a dimmer rated for

600 W of incandescent lighting. (Fitted as a replacement just before dimmable CFLs became affordable. ;)

John,

Thanks for that. It will be a blanking plate over the original back box, so I'm reassured that I can use chock block. Those Wago terminals do look very neat though.

Graham thanks for that. The LEDs are certainly dimmable. The writing on the switch unit reads:

Derating may be required, read instructions before use. BS EN 60659-2-1

60 - 250 VA TRANSFORMER PRI 230 - 240V 210W MAX

Should I replace it with something different? And if so, what?

It's brown. You might have read in my other recent replies that the puzzle is now solved, but thanks none the less for your post.

Funnily enough I've used that method in the past.

Not sure any LED can be smoothly dimmed to extinction then up again. Seems to remember that problem in the early days of LEDs in a TV studio. They seem to need a sort of 'strike' voltage. So could be the dimmer makers set the minimum to above this?

TLC will sell them individually if you want (rather than buying a whole box)

Being careful not to fall foul of cables only run vertically or horizontally from a visible accessory. A blank plate counts as an accessory.

John,

That's useful to know, thanks. It's really quite galling to have to buy in (relative) bulk when you only need one or two items.

Yes, I'm familiar with that requirement: a short horizontal run from the existing box fitted with a blanking plate is what's planned. Thanks.

The ones I just fitted in my lounge will dim right down and go back again. But they won't start from cold on the lowest setting. You need the setting up a bit brighter to get them lit.

That may be your first problem - you probably don't have anything like that load from LEDs.

Might be a better bet...

Thanks, John. That sort of explains what I saw.

Oh, and they give a link to

where it suggests you can get people to switch off their ad-blocking and return to your site.

Wrong. If you block Adblock, I simply never come back. Ever.
