Hi, guys. What do you think of using magnetic low voltage transformer 120/12 V with a rectifier to run 12V DC LEDs. my company has been installing them for a while now with great results.

More importantly they need to be listed to be used together...I think it is an NEC violtion.
Article 411 requires the components to be listed.
We assemble things all the time that are listed, but the end result is not an individual listed item.I would ask my insurance rep what they think about using, selling and installing an unlisted shop built device.

A home, business, industrial plant is not a listed item, it is built out of many listed components, and some that are not listed.
We all do it or have. Our inspectors have taken the attitude that we do not create industrial control panels by custom building an assembly of items that have some sort of listing individually. As I understand it, if I started making cabinet after cabinet as a Pivot Mfg does, they would take an entirely different viewpoint.
Why I think making my own power supply for LEDs is different, I don't know.

Is the transformer a listed class 2 transformer? is it a class 2 circuit?

It's not me. my boss wants electricians to install magnetic transformers with rectifiers from radioshack. to make it more weird those installations go to multi million hi end residences. inspectors overlook low voltage installations here and this combination works every time. on my job i connected this invention with led strips ;

and it looks good
recently i had in my hand similar device from reputable manufacturer
