Arkanis and Peter... kind of a side-suggestion...
I discovered how awesome and helpful a head lamp can be at work!
I did a 2 month stint underground in the storm sewers last year, epoxy sealing newly laid pipe joints. We all wore those little LEDs on a sturdy elastic fabric headband (you can usually find them in the sporting goods section), and they proved essential to working in the dark when mobility was a factor.
I've used mine since to hunt for mantids and feeder insects at night... works great! No "third hand" person holding a flashlight needed... although a friend and more hands might still be a big help, not to mention more fun!
But the lights are small, lightweight, relatively bright, and last quite a while before having to change batteries (AAA here in the US, at least. Hmmm... are batteries different in the rest of the world?
)
I came home one evening and saw my neighbor trying to finish cleaning out his gutters in the rapidly failing daylight, on a ladder with a flashlight. He went out and bought one of the headlamps the next day after using mine to finish his project that night, lol. They really are great for a variety of uses.
Good luck finding them!
