Top 7 Flashlight Strobe Usages – When & How To Use It

Tactical flashlight strobe creates very disorienting visual sensory effects towards an attacker.

In most cases, it’s designed for close-quarter self-defense & attention-grabbing. The question people have asked is:

When to use high lumen strobe? And how to safely use it.
So you’re here to learn… and we will cover the 7 most appropriate times to use a strobe light & the effects of it.

Whether you carry an EDC tactical handheld light or a gun with a weapon light.

It’s important to know how to use the strobe mode for deterring threats and keep yourself and others safe.

Top 7 Flashlight Strobe Usage

  • Self Defense – (Disable an attacker’s vision)
  • Outdoor Survival Signaling – (Get help)
  • Warehouse Operations – (Safety & Awareness)
  • Attract Immediate Attention – (Get Noticed)
  • Crowd Control – (Get out of my way!)
  • Illumination – (Use as a light source, Not recommended)

What Is Flicker Vertigo – How Disorientating Effects Are Felt

Flicker Vertigo is also called the Bucha Effect. Its an imbalance in brain cell activity caused by exposure to low frequency flickering high intensity light.

In another word, high intensity fast strobe lights flash near human brain wave frequency causing uncomfortable experiences such as nauseous, dizzy & disorientated.

Possible Strobe Light Health Effects

  • Disoriented or Nauseated
  • Rapid eye movement
  • Loss of motor control temporarily
  • Muscle rigidity
  • Blindness
  • Seizure

This is why a weapon light with strobe is considered almost like a tactical non-lethal weapon. It’s effective when disabling an attacker’s visual sensory. It slows them down and gives the defender the chance to gain tactical advantages.


How To Use Tactical Light Effectively For Self Defense- High Beam Or Strobe?

In a defensive situation, nothing is absolute as far as which light mode is better.

Things change rapidly & a strobe light can be effective until it’s not. Therefore it’s important to understand its limitation.

The hot light beam is good for blinding the threat to prevent him or her from seeing.

Strobe is to disorient the threat to slow them down.

Lumen Matters

A strobe light flashes at the same lumen intensity level as the light. So if you have a 1000 lumen white light, then the strobe mode will be 1000 lumens.

So far a light with adjustable lumen intensities aren’t available.

So how much lumen intensity do you need for effective self defense applications?

Generally, anything above 500 or even 1000 lumens is enough to get someone’s attention. Please check out our breakdown on lumen intensity on our site here.

Does the strobe flashing speed & frequency matter?

Of course, it does especially for personal defense. The faster it flashes the more disorienting the visual effect is on the attacker.


When Not To Use Strobe – Common Sense!

When basic illumination is needed in the dark, it’s unnecessary to use strobe. Just that simple.


Does Strobe Light Pose Danger To Your Eyes & Health?

Have you ever been warned before a movie starts about sustained light flash could result in photosensitive epilepsy?

You probably have seen it.

Exposure to fast & bright strobe light can pose health risks especially for people who has the tendency of getting recurrent seizures due to abnormal electrical activity.

Be cognizant when using a high intensity strobe light in close quarter low light self defense situations. Even you as the defender can get blinded depend on how you use it.
