I use candles when the electricity is not available

colord led lamps that clip onto stuff and clip it onto your hat or back pack if you where it when your bombing work great the color makes it less obvius.. but i usually use a big as mag light and if its a sketchy spot throw a couple white socks over the light part to defuse the light and make it softer.. or if you got cash to blow go on a cinematography website like B&H photo/video and get a backround flood light.. make sure it says SOFT and FLOOD not spot lights
The moon is a good option.
streetlight, moon, other lights( signsm, shops, traffic lights) head light would look really skechty, might get you shot...
white paint then a black outline works for me in dark ass spots with next to no light. I just adjust my eyes for a bit before or while im headed to a place at 3 am.
Of course the moon lol if it's a hidden discrete spot where you can't be seen I simply use the flashlight app I have on my phone.

I usually have a crew follow me around with about 8 giant spotlights.. I like to light my wall up like a football stadium.
The spots that are that dark are usually practice spots so its up to you if you want to bring a light. The abandoned warehouses out here are pitch black in some most spots and light in others because of the streets lights shinning through the windows. ..the spots that you want people to see are usually lit by street lights, the moon on occasions, etc. I always say if there's light where your about to get up, its a good spot.
