Use old halogen transformer with new LED Lights?

[Old Blevins]

My old halogen lights have mostly given up the ghost, and I'm looking at replacing them with submersible LED lights. Right now all my underwater and walkway lights are powered off a single transformer and everything goes on and off at the same time - which I like. So I'd like to power new LED lights with my existing transformer (an Alpine model PTST-30012). Does anyone know of a problem with this?

As long as your new lights are for 12VAC, it should be fine.
