I am usually not in one area for long as I do mostly service calls and smaller jobs. I use a headlamp for 99% of my work. If I need more than that, I plug in an LED floodlight into a cord if there is power on site. Most of those times though I am helping out on some bigger service change or outage with my co workers and we bring a generator and multiple LED worklights. On a few jobs we temp wired a cord from the generator into electrical room lights while we changed a large service.
