Question 1: Is there a spotlight that i could buy and control directly from
Question 2: How would i control a 12v flashlight/spotlight with a relay and the ez-b
Question 3: Which would be easier or more powerful.
I am new to EZ-B, but if you can toggle a led or switch led on and off with EZ-B, you can switch/control relay. Obviously most probably with transistor. I say this because I got a led toggled on and off with simple speech via the ARC. To replace the led with transistor, resistor and relay should go well.
A TIP 120 transistor lets you use a DO port as a switching port and you can get the power from anywhere.

Another option you can try is something called a PicoSwitch, and I find it makes things much easier.

The PicoSwitch is nice. It costs $19.99 + shipping.
Another one that has four relays for $28.95 + shipping can be found here: superdroidrobots.com
The parts for the 2N2222 circuit above are about $2 to $5 depending on where you get them. It just depends on whether you are comfortable building your own circuits (which I love doing for something like this application)
@rgordon I agree the less expensive way is to just build the circuit, but the switch I mentioned just makes it easier (and more expensive)
