The Lighthouse Core has the ability to light one hemisphere or two. Plus, each side can increase its brightness by the turn of a knob.
Most lanterns only have the ability to adjust their lighting with the push of a button. The Lighthouse Core, however, offers a unique feature allowing you to set the brightness to your choosing.
For instance, it has a low / high switch with a rotating knob that gradually increases, allowing you to set the brightness to your desired level.
As a result, with only one side lit, this lantern can burn from 8 to 350 hours depending on its brightness. With both sides lit, it can burn from 4 to 200 hundred hours. Again, depending on its level of brightness.
Because you totally control the brightness, the dimmer the light the longer it will last. Hence, the extreme range in burn hours.
