Used with long version of the very bright COB LED light modules.  Simple design to allow hooking the lights over gazebo or tent structures, vertically or horizontally.  COB LEDs are super bright and illuminate amazingly with very low power consumption.  Use Nylon or polycarbonate bolt sets to secure the LED modules to the hook (as seen in photo).  If you make hook sets for 6 LED modules and daisy chain them together running off a small 12V battery (or your car), you can illuminate your camp site for a very long time.
