Reviewed by Tim - 13th Aug, 2018Check this out before spending more!Bought these on account of their price and small size (I managed to pack one in the hole of my roll of duct tape). One was for my tent, the other for our gazebo. The latter even survived being waterlogged and gave out a decent amount of light for its size. There are also two brightness settings and some emergency red flashing setting as well. Whilst I don't know how long these will last, I do plan on getting the most out of them.
