Be careful. Measure the output voltage, and make sure the lights are only seeing 12V after the rectifier. Cheap transformers often output much more voltage on low loads- and you LEDs will BE a low load. Too high a voltage, and your LEDs will fail from overcurrent

I would have to say yes.
my reasoning is if you hooked up the led strip up to a 12v car battery it would work because it would only draws 6A even though the battery puts out much more. I believe the same would be true for the transformer.

What's the input on that transformer? If it;s AC then you'll need a bridge rectifier so you will get DC from the transformer. Also some smoothing caps would be good.
