It lasted 10 nights of free camping without a battery change. It is relatively low light, but it is enough to fully illuminate a 4-person tent. With 2, we didn't need extra light at night. Attention! The seller suggests AAA batteries, but it works with AA.

For the money, it is a very good choice, it opens and closes easily, it adequately illuminates a scene, but it also does the job in larger spaces, for example, a medium-sized room that I had to use it in.
