These lights are just fantastic. Great for any emergency lighting like power outages. We lost power twice this summer from terrible storms with high winds. It was out for 3 1/2 days the first time during the hottest part of summer. It's bad enough when you can't run the a/c with my health conditions. I also have several large capacity power banks so combined with these lights and a small USB fan we had light and a little air circulation for the entire outage. These lights have 2 brightness settings and a strobe too. A power bank built in as well. The light from these are quite substantial and a convenient hanging handle with a carabineer to attach it most places. It also has solar charging for additional charging capabilities. So don't be left in the dark without power for you cell phone and other small USB devices. These are also available at an incredible value.
