What lights would you buy?

Hey y'all I'm getting into lighting and taking it more serious,

I have a budget of around $600-$700, I'm shooting with a iPhone 15 pro as it has log and there's no point spending my whole budget on a camera and lens, therefore I thought it'd be better spent on lighting as I have none.

Here's a link to some images I really would like to recreate in terms of lighting, there's also a video in there with a light my friend offered me, he has a few of these as he's a electrician, would it be of any use? Or would you say I need "proper" film type lights
