This may sound far fetched but I'm posting this on behalf of my friend. He's going to have a few assignments working at night (pitch dark) setting up scaffolding for stands at a golf course next season. The location is away from the city with little light pollution at an exclusive club. So he asked my advice on bright lights with decent runtimes, which I don't know much about. I did lead him to HID's which sparked his interest and he has targeted the Polarion X1. Any advice from the flashlight/HID guru's would be great. It won't be carried constantly, but placed on the course or on golf carts so weight isn't an issue.
