Without being too flippant about a serious problem, right now one of the things I’d be looking for is a torch.
Ledlenser seems to have a solution for any of your lighting needs. This product, called the iF3R, is one way to light up your world. This heavy and sturdy device can cover an area with 1,000 lumens of light. It’s so bright, you can’t even look at it. Better still its metal construction should see it brush of all kinds of carnage.
It even has its own cooling system on board.
On its lowest setting it will last for 15 hours. The device charges via a magnetic charge system, so it’s even entirely waterproof.
