In ourhumble opinion, lumens are not necessarily as important as you might think. This is because the lumen rating that manufacturers use to market their products are not always accurate, and in addition, each company uses different methods to test that number.
The low end of the brightness scale for these camping flashlights is around 900 Lumens, however, some 900l flashlights will actually perform better than a 1200l flashlight from a different manufacturer. Things to pay attention to are battery time & recharge time, which are both pretty good indicators of how well a light can function.
On the other end of the spectrum is a camping light like the COBIZ 6000 LUMEN HEADLAMP. While 6000 lumens is a whole heck of a lot, there are some downsides as well. Namely, there are very few portable batteries that can power this many lumens for very long. While a company might say that it’s light can produce 6000 lumens, it will have a significantly reduced runtime at this setting.
