120V/12V Transformer with low voltage lights

I want to hard wire 4 outdoor 12V 1W LED lights on a photo cell switch. It looks like I can do that by utilizing a 120V/12V transformer, correct? Will the transformer draw current or just convert it?

If you are using a standard 120 volt photocell, just install it between the feed and the transformer.
I believe that Malibu makes a 12 volt photocell that you can put on the twelve volt side.
If you are worried about energy consumption, use the 120 volt photocell on the line side of the transformer.

Can you post a link to LEDs that you are using?
The basic LEDs like to be fed with a DC current source, so I'm curious how they handle this for the 12 vac supply.
