My preferred solution: an USB power bank with an integrated LED light. The power bank is a DIY version which is sold empty and can be filled with second-hand 18650 cells pulled out of broken power tools or laptop batteries (6 cells in parallel).
They’re sold from China for about 6 € and provide light for tens of hours when filled with 6 x 1700 mAh cells. I think the brand was “Haweel”.
