“Pot” = Potentiometer

It’s a form of variable resistor, used in controllers and dimmers.

The proposed set up would work, I have done it with sone LEDs in my buildings BUT I don’t change the brightness, it’s effectively a fixed resistor for me. As mentioned above LEDs not great at dimming.

I've got a bunch of LED GU10 bulbs linked to a suitable dimmer in the railway room.

Not sure if the LED strip (tape) can be controlled that way but I'm sure one of our resident experts can advise.

I have a couple of 12v, 5M long warm white strips in our conservatory that do a grand job. No problems with loss of adhesion or output despite the high temperatures through the last 2 summers.

Many offers if you Google  - I've had good service from these people:

Talking of dimming LED's - came across these earlier today whilst researching the subject, (I am a bit like npn) -

I have ordered a packet, (from USA),  as I have some LED's that will require, well ....... dimming.  :)

Absolute rubbish,leds can be dimmed just as well as normal tungsten lamps with a suitable dimmer,the only area were theres problems is right down at the bottom of the dimming range,leds tend to snap off instead of a gentle fade.Resistive dimmers (pots)  are ok for small led loads but above a watt or 2  pwm dimmers are the way to go.

Maybe I am being over cautious.

I am basing this on recent experience with LED bulbs for bedside lamps. The lamps I have are dimmable, LED bulbs purchased were expressly for use with dimmers (others in the range baring the warning “non dimable”).

Appreciate if the application Nobby is after is on bulbs with an order of magnitude lower voltage / current than the mains,  my concern may be unfounded.

Thanks David, but they are still not adjustable according to mood, background light as, once the stickers are applied, they are still of one brightness.
The sort of thing I am looking at can be found here. The dimmer can be seen bottom right........

Well, if you are going to get all moody with me .......  :P  :)

I realise it is from Hong Kong, but this seems to be the same thing http://www.ebay.com/itm/12V-8A-LED-Light-Protect-Strip-Terminals-Dimmer-Adjustable-Brightness-Controller-/263154189995 at $1.92c

Those prices look pretty good, Mick. Wonder if any of those are dimmable? Maybe worth asking.

Being able to vary the overhead light level can make a real difference, especially if like me you like to see the layout with its own street, buildings and yard lighting.

Adds atmosphere to the whole thing.

I'd like to have some coaches lit too but that's quite an investment which will have to wait.

PS: Just 'found' these that say they are dimmable:

Neat find from David - that may be a solution!

Nice find, David. It's exactly the one shown at Direct Train Supplies.
I'd still need a wallwart to bring 240v down to 12v or so.
