Recently I purchased some Lutron Maestro dimmers. When I went back to get more I mentioned to the sales person I was putting in Halo low voltage recessed cans. When she heard that, she told me I needed to purchase the Maestro dimmer not for incandescent but for magnetic transformers. She informed me if I did not the transformer would eventually burn out.

My question is to find out if she is right about this and also learn more about the technicals of why a different kind of dimmer is required for low voltage lighting.

Many thanks in advance,
