How Long Does a Flashlight Last?

How Long Does a Flashlight Last?

, by Chas Waters, 3 min reading time

When you’re looking to buy a new flashlight, its lifespan is likely one of your top considerations. Since flashlights are often used in emergencies, you want a flashlight that lasts a long time since you may not know how long you’ll need it. Many flashlight options in-store and online do not specify how long they’ll last — here’s our guide for estimating flashlight life.

How Long Do LED Flashlight Batteries Last?

One of the main factors that determines a flashlight’s lifespan is the battery. Several elements affect battery life, including:

  • Power draw: Low, medium and high brightness settings require a little to a lot of battery power.
  • Brightness: The lower the lumens, the longer the batteries will run.
  • Battery type: Alkaline and NiMH batteries last longer than “heavy-duty” options made from zinc-carbon or zinc-chloride.
  • The number of batteries: More batteries means more energy capacity, resulting in a higher run time.

The most common batteries for LED flashlights are:

  • AAA
  • AA
  • CR123A
  • CR123

Depending on the power draw, LED flashlight batteries can last 1.5 to 7 hours on high and up to 50 hours on low.

How Long Do LED Flashlights Last?

While the actual lifespan of an LED flashlight varies between manufacturers, one thing is true — they’ll last much longer than an incandescent flashlight. LED lightbulbs last anywhere from 50,000 to 100,000 hours, which is much longer than most flashlight bulbs. LED lights are very efficient, which helps increase their lifespan. This makes LED flashlights ideal for emergency kits, camping or anytime you need quick access to a bright flashlight.

The average flashlight emits about 100 to 200 lumens. These flashlights tend to be smaller and better for everyday use with more general and normal applications.

This extended lifespan is due to the flashlight’s UNROUND design that can hold four batteries. With more batteries comes more power for higher brightness and longer life.
