Why AC?

I want to build led lights for automotive purposes (12v and 6v) The power supply will be at my work table and be hooked to my breadboard . I've found one on Ebay; Lascar Benchtop Lab Adjustable Power Supply 1.5-30v(>$50) I would like to find others before I commit.

Dude really? 12volt direct current. Don't reply!
Rude much?

I'm trying to help you out here. I'm asking questions to get more clarification of what you need. You say you are trying to make LED lights for automotive purposes. So the 6V to 12V makes since. I'm just trying to figure out why you want an AC power supply when car power systems run at 12VDC.

My house runs on ac current as most do in case you didn't know that. I've been saying that I want an adjustable power supply that I can use IN MY HOUSE,AT MY WORK SPACE that will plug into the WALL SOCKET OF MY HOUSE and produce dc current at ranges of 2.0v to 12v .FIX YOUR POCKET PROTECTOR AND IGNORE ME.GO HOME SHELDON!
I'm not aware of any cars that use 12VAC for there internal electrical systems.
I presume AC input...

@author, yes, yes they do.

Depending on how you drive the leds, they may be
Constant voltage (most wall warts are)
Constant current (specific led drivers are, but they're only good for that type/power rating)

Variable output: These are more rare but do exist. Often referred to as variable power supplies, and can include features of all the above -- constant voltage or current. They aren't good for production runs because they have so many extra features, but they are really good for figuring out prototypes.
