The packaging states 12V DC and 24W, so... 2A? (ohms law).

Seems a reasonable assumption.

You are best using a logic level FET to switch this.

Any specific one?

I have never used and know basically nothing about those transistors, whats the basic difference in the field effect type? i would have to do some research while i'm at it.

From what i understand so far, you tell me to use a FET since it has a huge resistance, allowing for practically any current to go through and not damage the semiconductor?

No it has a very small resistance.
