Running 24v led lights through a dimmer. Help!

[BayerBalls]

Hey everyone,

First time post. Any help would be hugely appreciated.

I am attempting to run some led lights purchased on eBay, through a dimmer. Lights and dimmer are both 24v.

I feel like everything has been done correctly but the lights just turn on as usual and the dimmer does nothing.

I also tried with a 12v dimmer and same result. The only thing I think it could be is maybe the wire was cut on the wrong side of the transformer?

Pics are attached. Thanks in advance for any feedback.

What is the device feeding the dimmer and do you have a link to the dimmer?

I hope the white plastic 'lump' in line with the cable is an AC-DC converter..... show us some details.

If it's just a switch then you've blown the guts out of the dimmer!

Are you poking mains voltage into a dimmer rated for 12-24VDC?
