How to Measure the Throw Distance of a Flashlight?

a human using a flashlight

You can calculate the throw distance of a flashlight in three easy steps;

  1. Measure the lux
  2. Calculate the candela
  3. Calculate the distance in meters (yards, miles)

Note: You will need a reliable lux meter, a tape measure, calculator and a flashlight for the beam throw.

Step 01- Measuring the Lux

  1. Choose an object to focus the beam on. A large wall works best.
  2. Use the tape measure to set the flashlight around 15 meters away from the wall.
  3. Use a tripod (or some support) to place the flashlight at this point.
  4. Slowly move the sensor of the lux meter through the beam until you find the highest lux reading.

Step 02- Calculating the Candelas

Calculate the lux numbers at 1 meter using the formula below;

Lux numbers at 1 meter = Lux x Distance x Distance

For example: If you measured the lux at 25 meters to be 1600 lux;

 1600 lux x 25m x 25m= 1,000,000 lux

The lux measurement at one meter equals the candela rating;

Therefore 1,000,000 lux = 1,000,000 cd = 1000 kcd. 

(You can use an online calculator to help you with this)

Step 03- Calculating the Distance

Use the formula below to calculate the beam distance in meters using the candela count calculated above;

Calculating The Distance

What to Consider When Choosing a Long-Distance Flashlight for You?

Getting a flashlight to match your style and needs is essential. Consider the following factors when making your decision to make you buy the best flashlight for you.

Light Output

The light output is measured in lumens. The brighter the light, the higher the lumen count. 

Long-distance flashlights should have a considerably high lumen output in order to shine over a long distance. The long-distance flashlights that made it to our list have a range of 1- 6300 lumen strong light.

A bare minimum of 1 lumen light on the lowest setting can last up to 180 days, and the 6300-lumen output on the highest setting can last up to 1 hour 45 minutes.

You can refer to the below brightness chart to help you choose;

  • 4000-2000 lumens: Extreme brightness- equal to most car headlights
  • 2000- 1000 lumens: High brightness- ideal for military use during search and rescue missions
  • 1000-500 lumens: High-medium brightness- good for tracking animals at a distance
  • 500- 200 lumens: Medium brightness- to follow blood trails
  • 200-50 lumens: Low-medium brightness- good for hiking and camping

A long-distance flashlight with high- medium brightness is suitable if you are choosing it for hunting or similar activities. Similarly, different brightness settings are ideal during different situations.

Beam Distance and Intensity

The distance of the beam throw is measured in meters, and the intensity of the beam is measured in candelas. 

Spotlights and focused beam flashlights have large throws, but floodlights will have wider beams with short throws. 

A good long-distance flashlight should have a strong, focused beam with a minimum throw reaching at least 350 yards. 

Run Times and Battery Life

Flashlights with higher lumen emission mean lower run times. Those that have multiple brightness levels will have different run times. 

Battery type and life is a must consider when choosing a long-distance flashlight. Knowing what they work on will help you prepare for recharging or replacing with extra batteries. You don’t want to struggle with fading lights amidst any of your activities.

Most of the long-distance flashlights on this list run on rechargeable power sources. So having a power bank to recharge during urgent situations will come in handy.

a human using flashlight for long range

It would be best if you chose a long-distance flashlight that will last you long enough through your activities.

Size and Weight

In general, no one wants to add weight to what they carry. Everyone tries to keep it as light as possible. So the weight and size of the long-distance flashlight matter. 

Long-distance flashlights are usually big and bulky in size. So choose a model with a reasonable weight range. Do not choose a heavy light unless you can commit to it.

Quality of Waterproofing and Shock Proofing

Durability, weather resistance, and shock proofing are essential to consider, especially if the long-distance flashlight is to go through different weather conditions, extended environment exposure, or rough use.

Most long-distance flashlights on this list have at least a minimum rating of IPX6 in waterproofing, meaning it is extremely waterproof and impenetrable by weather, making them perfect for outdoor use.

And obviously, you don’t want a light that will break when you drop it. So your long-distance flashlights should have gone through drop tests and have at least a 1m impact resistance.

Finally, the price. Long-distance flashlights are expensive for the features they offer. Some can be super expensive, and some will fit right into your budget. Even if you’re willing to spend lavishly, you need to choose a flashlight that will offer you the best features for the price you pay.


So what’s it going to be? Are you going to grab our top recommendation, or are you going to explore your options with the other flashlights on this list?

No matter what you choose or what drives your deciding factor, we hope this review has simplified the process for you and helped you make your purchase.

We hope the flashlight you choose fulfills your requirements safely and successfully.
