Beam distance is determined by light output and headlamp beam type.
Differently angled lamps can have drastically different beam distance even if their light output is identical. Once again, make sure you know what you want to use the headlamp for.
Lamp life
Headlamps with high light output tend to have shorter run time or higher weight, since they have to accommodate either more batteries or one larger battery.
LEDs themselves have a lamp life of tens of thousands of hours, all the way up to one hundred thousand hours.
Power
The lightest and smallest headlamps with low light output are usually powered by button cells.
Most headlamps use AA or AAA batteries. They are inexpensive and easy to buy and replace.
Powerful headlamps are energy-intensive, so they are equipped with rechargeable batteries.
Other features
Increased mechanical durability – these headlamps are resistant against vibration and shock and are generally made of hard plastic, light and tough metal alloy, and can have rubberised components.
Water-resistant - resist fog and rain, but cannot be immersed in water.
