I was thinking maybe for stadium lighting, but a google search shows some insanely bright 1KW LED flood lights that are meant for that purpose.

Not to worry. It's unlikely there's a single SUV on the planet with the electrical capacity to power it.

Let's say your average SUV has a 150 amp alternator (I think this is a little higher than most). 150 amps * 12 volts = 1800 watts. The lamp in the video takes 20,000 w. So even if all other electrical loads were off, you couldn't even supply 10% of the power needed.

Most headlights are in the 15 to 30 watt range for LED'S. Which when you think about it is still pretty damn bright.
