This light is bordering on too good to be true.
It is incredibly bright. Put it this way, we had it in our tent with a full-size camping lamp - this tiny light lit up more of the tent, and was brighter, than the camping lamp.
The first time I turned it on, I looked straight at the LEDs as I thought the light would be wimpy - big mistake.
One of these lights up and entire room in our family tent - it is good at short-range, bright illumination. Perfect for inside a tent.
One incidental but great feature is that the hook size is perfect - not so small as to be weak but small enough to fit in that little hole in the zip tab (that you pull to open & close the zip) on the door of a tent bedroom (well, it fits ours. If it doesn't fit yours, you could just put some string through the hole and make a loop). No more waking in the night and wondering where the torch is. It also means you have a massive tab to open and close the zip.
The hook folds into a recessed area in the rear of the light. To get it out, just flick the light (I couldn't lever the hook out with my finger). The hook then pops out enough to pull fully out with your finger.
I hooked the light through the zip tab and had plenty of light to read by - far more than with a torch.
Having bought one for a camping trip, I returned and bought one for each bedroom of our tent & the lounge.
