What is this thing attached to the device box?

Hi all,

Recently acquired a home and removing some old lighting in a finished basement ceiling. I saw this attached to a device box removing a fluorescent light fixture.

The fluorescent light was not connected to this box, this device box is chained to 6 potlights.

Anybody know what it is and what it does?

Thanks!

It's a transformer for low voltage wiring. Does the wiring go to a doorbell? Or thermostat?
Perhaps! The door bell chime box is in an air return nearby.

Thermostat - probably not as I see a lot of wiring from the ceiling in the furnace room, and that is much further away.
The op seems to think it is associatted with some pot lights ?
if this is so ?
then perhaps they where low voltage pot lights ?
remember anything is possible in DIY land !

So true. Apparently the transformer and junction box were buried in the finished ceiling.

That doesn't look like standard 18 gauge bell wire or thermostat wire coming off the transformer.

If I had to guess, I would say it's lamp cord

All we can tell you is that it is a transformer,
probably low voltage 12 to 24 volts
We can not tell you for sure what it powers ?
you could try diss-connectting it and see what doesn't work ?
most common things are door bells or thermostats.
But anything is possible.
let us know if you work it out ?
The fact that it is powered off a lighting circuit does not mean it is associated with the pot lights.

Most of those transformers will only produce 20 watts +/-.
Most likely the door bell.

I don't see where the lamp cord comes in. I see a black and a white wire connected to the LV side of the transformer.

The white cables appear to be MND-90, the Canadian equivelent of Romex.
op says the transformer was "chained " to six pot lights ?
I am not sure about the term "chained"

he most likely means wired together as in daisy-chained.

The OP didn't say the transformer was chained, he said the device box was chained to 6 pot lights.
