Although this Ozark Trail headlamp is not quite as well constructed as my $72 rechargeable lithium Petzl Tikka XP 2 Core or my heavy-duty $21 Smith & Wesson Galaxy 6 LED Flashlight, it does have impact-resistant construction, lifetime LED bulbs, adjustable aim and an adjustable head strap. It is powered by 3 AAA batteries (included). These will give you 6 hours of run time at 150 lumens (90 meter beam distance) or 66 hours at the low setting (15 lumens / 28 meter beam distance). The red setting has an output of 2 lumens, and 35 hours of run time.
