Flashlight Review: Jetbeam WL20 Hunting Flashlight

The Jetbeam WL20 is marketed as a multicolored hunting flashlight. The purpose of the colors is to help blood droplets become more visible. This helps hunters track wounded game animals, such as deer.

In all honesty, I have never used a hunting flashlight to track deer. Typically, the red blood droplets stand out well on leaves and pine straw. It also helps to understand how animals react when they are injured.

For this review, the Jetbeam WL20 hunting flashlight we will be looking at typical, everyday usage. Which means will the light survive being dropped several times, how easy is the light to use, and how bright is the Jetbeam WL20?

Color is changed by turning the flashlight head.

Jetbeam WL20 Testing

The Jetbeam WL20 was subjected to a drop and submersion test.

Drop testing was done by holding the flashlight around four feet off the ground and dropping is several times from different angles.  The flashlight was also dropped directly on the face.

After being dropped several times from different angles, the flashlight continued to work and experienced no problems.

Submersion test was done by dropping the Jetbeam WL20 flashlight into a dogs water bowl that is around 4 inches deep.  The light was let in the water for a little over one hour.

At the end of one hour the flashlight was taken out of the water, dried, opened and inspected.  There was no water inside the body, on the battery, or behind the lens.

Nighttime Testing

The Final test was to full charge the battery, then take it to a field here on the farm and see what the Jetbeam WL20 can do.

White light: 1,000 lumens of the Jetbeam WL20 was plenty bright to light up a section of a field here on the farm.

Red light: With a high setting of 125 lumens and a low of 20 lumens had nice variation.

Green light: Has a single setting of 200 lumens which seemed overly bright for up close viewing at night.  It would have been nice if green had a low setting.

After using the flashlight for several minutes, condensation developed behind the lens.  I do not know if the moisture came from the submersion test, or moisture from when the flashlight was assembled.

Final Thoughts

The WL20 fixes a common problem found on a lot of flashlights this size, and that is button placement.  On a lot of flashlights, the brightness or on/off button is located on the side, which makes it difficult to find at night, or while wearing gloves.  The Jetbeam WL20 fixes this problem by moving the on/off and brightness selectors to the tailcap.

The flashlight can take a little getting use to as there are three ways to adjust the light:

  • Tailcap on/off
  • Adjustment button on either side of the tailcap
  • Turn the head to change colors

Once the user has figured out how to operate the flashlight, things get easier.

Overall, I found the WL20 easy to use and plenty bright for its intended purpose.  I just wish the green had a lower brightness setting.

Final score is around a 9.8 out of 10.

A couple of points were subtracted for the flashlight only coming with a 2600 mAH 18650 battery, and the lanyard holes being too small for 550 cord.
