Sometimes when it comes to tactical flashlights, you are simply looking for the biggest and brightest. For tasks like search-and-rescue, perimeter security, and work in remote locations, we have two tactical flashlight recommendations for you to consider: the Fenix LR80R and the Fenix LR50R. While there are several options for great tactical flashlights by Fenix, these two are the brightest tactical flashlights out there. When comparing these two, it’s best to start with the most obvious feature: their size.

What are the biggest and brightest tactical flashlights from Fenix Lighting U.S?

The LR50R and the LR80R are the biggest and brightest tactical flashlights from Fenix Lighting U.S. Both of these flashlights pack a powerful punch and will provide you with the brightest light in any situation. Big, bright, and powerful, count on the LR50R and the LR80R for all your lighting needs.

Biggest Tactical Flashlights

These are two heavy-duty flashlights, and they weigh in as such, with the Fenix LR50R packing a punch at 34.8 ounces and the LR80R graduating to the heavyweight class with its 57.7 ounces (with batteries). That weight difference is partially due to the fact that the LR80R is a little under four inches longer than the LR50R (10.2” and 6.42” respectively), however regardless of size, the two both have plenty of lumens to work with.


Brightest Tactical Flashlights

When we talk about the brightest tactical flashlights, we need to point out that, to you, “brightest” might mean that you can light up a designated work area, whereas someone else’s “brightest” might mean lighting up an entire section of land in the middle of the night.

While it’s true that the Fenix LR80R and the LR50R are both bright lights, they are different in how they throw the light. The LR50R is a truly powerful spotlight blasting 12,000 lumens over 3,117 ft (950m), whereas the LR80R is brightest when using all 18,000 lumens. These flashlights are not only bright but are also rechargeable.

Powerful Tactical Flashlights

Both the LR80R and the Fenix LR50R are rechargeable flashlights. However, the LR80R’s batteries are built-in. With the LR50R, users can pack extra rechargeable batteries for long trips between charging opportunities. When you’re wondering if it’s time to swap out the battery or not, go ahead and check the battery-level indicator of the LR50R, and you may also charge other devices thanks to the discharge function of the instrument. On the LR80R, the flashlight has a built-in 7.2V/12000mAh Li-ion battery pack for optimal performance. The LR50R includes an intelligent downshifting feature to automatically downshift the light’s brightness to prevent accidents or injury from the excess heat.


We’ve covered some of the basics that differentiate the Fenix LR80R from the LR50R, but of course, the best way to know which one fits your needs is to dive into the details.
