Run Time: This refers to the time a flashlight takes while lighting before it power drops to 10% of the rated output. The runtime usually depends on a given light mode, some modes are brighter than others thus using more power than others. A higher run time while on the brighter mode the better the flashlight.

Bulb Type: LED bulbs are mostly preferred as they have a longer lifespan and are more efficient than the normal incandescent bulbs.

Output/Lumens: This is simple a measure of light output. It refers to the intensity of light on the highest brightness setting while on new batteries. They vary greatly from 20 lumens to (The lowest light enough to read) to a blazing 3500 or higher lumens (enough light to cause blindness). Lumens depend on the flashlight usage/purpose.

Application: This is basically how far the light beam will travel before it starts to diminish. It is also referred as “flashlight throw”. Depending on the brightness mode, the beam distance will vary. Consider selecting a flashlight that best suits your usage e.g. choose a longshot with a narrow beam for rescue missions, flood light for camping and hiking purposes or a flashlight with different color modes for hunting.

Beam Type: Most flashlights have three types of the beam: spot, flood and adjustable. Other names that may be used to refer to this beams are focused for spot and fixed for a flood. Flood beams can be used for simple tasks like walking or camping because they have a single beam. The spotlights in other words have a condensed beam which allows it to travel for distance. The adjustment beams allow adjustment of the width between spot and flood.

Budget: You don’t always need the most expensive flashlight in the market. When you are on a hunt for a flashlight that can power outages and light uses at night, it is always advisable you choose a durable inexpensive high lumen flashlight. Many flashlight that use specialty batteries are expensive than the normal AA battery ones.
