Hopefully some electrical wizards can help me.

I have a few LED lights I'd like to run off a 12 V car battery. I know minimal about converting DC to AC or visa versa. Do I just need a converter? to get me from my 12v DC to power my 120v AC lights?? The light info is below

Any info would be appreciated. The simpler the set-up the better.

Thanks

 

Buy a car 12V-120V converter price between the 30-70$.
Building it yourself is dangerous and when build not correct it will produce a lot of unwanted radio frequencies.

 

Might be cheaper just to buy a 12V 50W light.

 

If for some reason you can't use a 12V floodlight, buy an inverter; it's impossible to build one cheaper.

 

I would buy a 12V 50w light, even if you use an inverter its still going to pull at leat 4 to 5 amps from the car battery.
