For Security and Law Enforcement officers, lighting up the night is essential to your situational awareness.  What comes to your mind when determining the best law enforcement flashlight?

In this article, we review the best law enforcement flashlights that you as a Law Enforcement Professional can use whenever you are on patrol. We also discuss the things to consider when buying the best law enforcement flashlight to suit your needs.

Here’s the quick list of the Best Law Enforcement flashlights:

What To Look For In A Law Enforcement Flashlight

Law Enforcement Officers need to depend on their gear in a way that civilians don’t understand.  Certain factors are important to consider when selecting your flashlight that may not be relevant in other situations.


Batteries are the single most important factor to consider when choosing a flashlight for Law Enforcement. Batteries affect not only the weight of the flashlight but also the run time and the brightness.

To put it simply, a rechargeable Lithium-Ion (Li-Ion) battery has more energy density than a standard Alkaline.  Li-Ion batteries put out a whopping 3.7v per cell compared to an Alkaline cell at 1.5v. This results in much brighter light with Lumens to deploy.

Nobody wants to be stuck with a dead rechargeable flashlight (they can take hours to recharge), so a replaceable Li-Ion cell and/or a flashlight that can be continually charging in your vehicle is also an important consideration.

The size will be a personal preference depending on your situation.  You may want a pocket carry light that you can carry in your vest or pants.  Or you may prefer one with a bit more heft that might deter an assailant.

There’s a reason that Law Enforcement officers would carry a hefty D-Cell Mag Light over their shoulder when approaching cars on a traffic stop.  They can make great clubs!

Type of Bulb

Incandescent Bulbs have their place, but for Law Enforcement and Tactical applications, you need the brightness of an LED bulb to light up the night.  An LED bulb is much brighter and smaller than a corresponding Incandescent Bulb. There really is no comparison.

Light Output

Lumens matter when selecting a tactical flashlight.  For Law Enforcement you need to decide if you want your light to have a narrow beam and long-throw for searching and following, or a wide beam to light your immediate area and increase your situational awareness.

Since law enforcement flashlights are basically meant for tactical use, the material used to make them ought to be heavy-duty and long-lasting. You will need to choose between metal for its’ smaller size and weight, and polycarbonate material.  It is really a matter of preference here.

What is not a matter of preference is durability.  Your light must take whatever you dish out, and do it in all weather.  Go for an IPX rating of 4 or higher.
