Looking for the brightest flashlight? ZDNET's top picks feature flashlights with up to 100,000 lumens to shine a light on just about anything.
Written by Allison Murray, Staff Writer on

Flashlights are an essential item for nighttime outdoor activities like camping or walking a dog, emergency situations, or whenever you need an alternative and portable light source. The average flashlight shines a decent enough beam, but if you're looking for something brighter, there are significantly brighter flashlights available. 

The world's brightest flashlight clocks in at 100,000 lumens, but our list also consists of flashlights that can reach 80,000, 65,000, and 34,000 lumens and have impressively long battery lives as well as built-in fans to keep them cool. We've rounded up the brightest flashlights to shine a light on whatever you need.

How did we choose the best and brightest flashlights?

We chose these bright flashlights through extensive research in the market. We compared lumens, IP ratings, beam distance, and different price points to provide you with a wide variety of options. 

What is a flashlight's lumens?

Lumens is a measure of the intensity of the light coming out of the flashlight, on the highest brightness setting. It may also be shown for multiple light settings. A high lumen output means that the flashlight shines bright. 

How many lumens is a good flashlight?

The average flashlight emits about 100 lumens. However, the higher the lumens, the brighter the flashlight will be. 

How many lumens is a smartphone flashlight?

Your smartphone's built-in flashlight only gets up to 40-50 lumens, so it is a significantly dim light compared to your average flashlight, and especially these bright flashlights. 

Are there alternative bright flashlights worth considering?

Here are a few other options to look into:
