LOOKING FOR OVERHEAD LIGHTING TO SKATE AT NIGHT

I'm looking to buy portable lights so we can skate at night. Apparently if you have the light too low, it casts odd shadows and it's annoying so ideally I want overhead light. I'd prefer it to be portable but it's not a Must.

Also if I take it down to where I wanna skate, I'd need some sort of portable power source that could power said lights for me to plug the lights into. My uncle said one of those strong enough to power those lights could be expensive.

If anyone has any suggestions I am open to any and all ! TIA

Just looking for any input if anyone has us
