Very good lighting.. I don't know about the autonomy because I received it today.. In a measurement I took, it draws 1 Ampere so I don't think it has a long autonomy.. The top part unscrews and can accommodate 3 AA backup batteries.. It also came with 3 AA batteries in the package..

The light is very good, quite powerful. I bought it for the case of a power outage at home and when I used it, it fully covered me. Be careful, there are other ones that look the same, much more expensive, and have the same brightness and quality as this one, only the logo on the outside changes. I have bought 3 with different prices for testing.

It does not illuminate at all - about as much as the screen (not the camera) of the mobile phone. In this case, you get what you pay for.

It is a very good economical light for camping. It was tested in a 3-day free camping in places without any light. We bought 2 and hung them inside our tent (5 people) where we were very comfortable at night. It requires simple AA batteries. I would prefer it to have a warmer lighting because it has a white cold light, but okay, it's a matter of personal preference.
