BEAVER FAQs & hacks

Flashlight Lingo


Lumens are the most talked-about unit of measurement when it comes to flashlights. Luminosity refers to the total amount of light being emitted from the emitter (the fancy new word for lightbulb, since they’re technically not bulbs anymore). So, the more lumens a flashlight has, the brighter the more light it’s outputting.


Lumens get most of the attention in the consumer flashlight world, but we also neet to think about the intensity and focus of light emission in addition to the total volume of light emission. Think about the same amount of water flowing through a 6″ pipe vs a garden hose — much different pressures from the same amount of water. Light emission is similar: you can have a very different flashlight experience with the same lumens, depending on how the beam is focused.

Flood vs Throw

Flood and throw refer to the shape of the light beam coming out of the lens. A “floody” light will have a wide pattern but that don’t go very far, very much like a floodlight on a house. Because of this beam profile, floody flashlights are great for interior and short-range applications. Most consumer-grade flashlights, like the ones you’ll find at the hardware store that people keep around for occasional power outages, fall into this category.

A “throwy” light, on the other hand, will have a narrow, focused beam that shines for long distances, more like a spotlight. These type of lights are ideally suited for tactical, defensive outdoor applications where distance and intensity are critical.

Our flashlight is designed with extreme throw, able to punch through the darkness up to 3 city blocks. This level of performance is unheard of in the civilian flashlight market, because the average consumer thinks of the flashlight as a contingency plan, not a daily practical or defensive tool.

The Role of the Handheld Flashlight

There are basically two schools of thought when it comes to an EDC (“everyday carry”) handheld, each viewing the light as a tool for a different job.

On one hand, the light is seen primarily an administrative tool (i.e., to replace the one on your cellphone when you lose your keys under the car seat). For a job like this, 100-250 lumens is more than enough, and anything more you risk blinding yourself for close-range use.

On the other hand, the light is seen primarily as a defensive tool (i.e., to illuminate and deter a potential threat from as far away as possible). For this job, you want as much horesepower as you can throttle in the palm of your hands.

Beaver Deets


This Beaver was designed to pack as much punch as possible in a comfortably pocketable size. At 0.9″ wide and 4.75″ long, it’s about the same size as two rolls of quarters end-to-end. The weight is a modest 4.25oz (about the same weight as one D-cell battery or a deck of cards).


Our flashlight ships with a premium 18650 3.7v 3500mah rechargeable battery, which is among the highest energy-output batteries available in this size. Rechargeable up to 500 times with no loss of performance, just one of our batteries will save you around $1000 in disposable batteries over its useful life. And when it’s time to replace, we’ll take care of you for less than ten bucks.



The BeaverBlaster’s output is ~1100 lumens with a brain-busting ~40,000 candela. It will run at 100% juice for about 85 minutes.

The flashlight head (the lens end) will get warm to the touch with extended use at 100%. We’re squeezing a ridiculous amount of juice out of a very big battery and a very small, very powerful emitter, and some of that energy dissipates as heat. Not to worry if it gets warm, we’ve got a built-in temperature regulation system so the light won’t overheat.

This light is best used in short bursts of 10-30 seconds at full throttle, which is why we designed it with the momentary switch. If you’re going to be using this for extended periods of time, we would recommend selecting a programming option with variable emission. 

Is The Beaver Thyrm Compatible

Absolutely. In fact, Canuck Tactical is an authorized Thyrm dealer. The Switchback 2.0 and LPC will both work perfectly with the Beaver handheld light.

Life hack: When installing the Switchback, you’ll find a little rubber o-ring in the package. We recommend sliding that over the tailcap prior to installing the switchback to lock it on and prevent rotation, as pictured below.

Can I Mount The Beaver on My Rifle?

Absolutely again. Keep in mind this was designed to be an easily-pocketable handheld, but you can certainly mount it to your AR or AK if you’re so inclined. An adjustable ring mount works the best. Pictured below, for example, are the Magpul V-Block + Ring mlok kit, which we have for sale in both M-LOK and Picatinny versions. Options like the Olight WM21 picatinny mount and Arisaka Ring Mount will be great as well.

Any standard fixed-diameter 1″ light mount will work, but you’ll need need one loop of electrical tape around the flashlight body to make sure it’s snug in the mount, since our handheld body is about 1mm less in diameter.

We do not currently have any pressure switches because again, this is primarily a handheld light, but it’s on the priority list and we’re working on it.
