One of the reasons it has so many good reviews is because many people still don't realise how bright modern LED flashlights are. Even the old 4 x D cell Maglites were only about 50-60 lm, as big as they were. Nowadays lights that are 20 times brighter (or sometimes far more) are common. And much smaller too. (I have a very small 1 X AAA light that puts out an honest 60lm and there are even smaller ones that put out more) Add in a cheap price and it's easy to see why they're so popular.

Like I said, they're okay as a "go to" light when the power goes out, or to keep in the car, but nothing I'd recommend for your purpose.
