Most modern flashlights generally use only LED as their light source. Let’s take a look at what parameters are important and what you should consider before purchasing.
Light output is measured in lumens (lm). Flashlights with a narrower beam have a longer beam distance even if their light output is identical.
Some models have multiple brightness settings.
Power
Smaller flashlights with more modest light output are commonly powered by button cells.
Most types use AA or AAA batteries. They are inexpensive and easy to buy and replace.
Powerful flashlights are energy-intensive, so they are equipped with rechargeable batteries.
Lamp life
Flashlights with high light output tend to have shorter run time or higher weight, since they have to accommodate multiple batteries.
LEDs themselves have a lamp life of tens of thousands of hours, all the way up to one hundred thousand hours.
Other features
Increased mechanical durability – these flashlights 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.
