BRINYTE PT16 Flashlight Review
SFT40 Cool White
21700 LiIon Battery
Tactical Dual Switch
Last Update 30-07-2025
This review is about the BRINYTE PT16 Tactical Flashlight.
The Package is ready to use and comes with the following:
- Flashlight
- 21700 Branded LiIon Battery, 5000mah-Button Top
- usb cable A/C standard
- a lanyard with slider
- 2x spare orings
- manual and papers
The light uses a single SFT-40 6000-6500K cool white LED, the declared Max Output on the website (on Level IV-turbo) is 2.000lumens , the turbo only lasts about 2 minutes, then the stepdown reduces the Brightness (and it goes to 820lm, declared).
The head is large being more of a thrower than a flooder, coupled to the SFT-40 are a metal smooth reflector and an A/R coated glass lens.
The battery as a (long!) protected button top 21700 LiIon with declared 5.000mah, the actual capacity should be between 4.500 and 5.000 mah, or that’s at least the capacity I got from recent 21700 cells.
Being a LONG battery, it cannot be charged via a classic battery charger, the only way is either a longer bay or the USB-C port on the flashlight.
The USB-C port is a standard 2A, I tested it and the average current was between 1A and 2A, a full charge takes between 2 and 5 hours depending on the charger, cable, temperature and battery status. The initial charge took 1-5/2hrs from orange to green.
The main switch is a forward-clickie, which means you have momentary-on, momentary only comes on on TURBO.
Turbo lasts between 1 and 3 minutes depending on the outside temperature, I’ve see that it visibly goes lower after a couple minutes or where it goes above 40°C (estimate).
Next to the main round button, you get a long switch which is the strobe button:
– when OFF it has momentary strobe, it stays on as long as you keep it pressed.
– With the light ON (main switch) you can change modes low-turbo, strobe can be activated with a long(er) press and this time it stays on as long as the light is ON, clicking the strobe button reverts to the last used mode. Being a “tactical flashlight” it is very useful.
Besides the 2x tail switches, there is a 3rd button, an e-switch this time, located to the side, here are some of its functions:
– with the light ON (main forward clickie) you can change modes, with a single click.
– with the light OFF, within one minute of the last activation you can turn it on (click), change modes (click) or turn it OFF (long click)
– with the light OFF after 1 minute you can unlock the light (3 clicks) and then turn it ON and OFF like before.
– after 1 minute the light locks, blinking 4 times
– interesting is that with the light ON, clicking it for 10 seconds, enables the LED to stay ON or OFF permanently, doubling as a locator/battery indicator.
– the LED within the button serves as a battery power indicator with GREEN (100-70%), ORANGE (70-30%) , RED (30-10%) and blinking RED (10-0%).
– lastly the LED also shows while charging (red) or with a charged battery (green) when the USB-C plug has a cable inserted
The Brinyte PT16 has 4 modes: (declared values)
LOW 10lm 16.800mins/280hrs
MID 130lm 1200mins/20hrs
HIGH 820lm 200mins/3,3hrs
TURBO 2.000lm 2+130mins
Added modes are STROBE and SOS
There is ATR Advanced Thermal regulation, that kicks in at 40-60°C and reduces the output to cool the light.
And lastly and very important, the light features LVP, Low voltage Protection, which turns the light off when the battery level is too low to operate safely.

Here is the BRINYTE PT16 Flashlight:
Here is the main forward clickie with momentary function:
Here is the secondary switch, when OFF it has instant full power strobe.
When ON it doubles as a mode switch, holding for 2 seconds activates strobe, one click reverts the previous mode.
A close-up of the 2 switches:
The 3rd switch is an e-switch with a coloured led in the middle:
The central tube of the body has some ridges to improve the grip in wet conditions or with gloves on:
The tactical ring on the body holds the clip in place and avoids rolling.
There is a lanyard hole both on the clip’s tip and on the tactical ring, opposed to the clip’s attachment point.
The ring and the clip rotate without unscrewing, so you can orientate the buttons to your liking.
The head has ridges to hold onto and has a non pointed strike bezel, to hit opponents.
I often read that striking bezel can break glass, I never tried but, I assume it would damage the soft aluminium and the anodizing.
The SFt-40 LED and smooth metal reflector.
The lens is glass with A/R coating, hence the purple reflection.
To charge the PT16 there is a potted (filled with resin) USB-C port under a rubber cover, the input is up to 2A charging current.
An A/C cable is provided for convenience, having spares is always good!
The rubber cover is not the best I’ve had, it has a mushy feeling and doesn’t cover the USB-C port so well, in fact mine got snagged somewhere in the backpack and the cover is damaged, both the rubber and the little nip that goes into the aluminium tube.
If you don’t pay attention it does not always go into it’s slot and might bring less waterproofness.
I have therefore not done any waterproof or freeze tests on this flashlight.
Here is the PT16 while charging.
I used the LBF rechargeable battery reviewed here
The LED under the e-switch shows the charging status, orange is charging, green is charged.
Here is a short video that shows hot to charge the flashlight:
The thread appears non square cut but rather a regular threading.
There is an o-ring for waterproofness on the tail of the tube, also, inside the tube there is a secondary aluminium tube that ensures current flow avoiding the main tube to be the connection between the tailcap and the head.
This should reduce the risk of sparks in dangerous situations.
Being thicker than the threaded part is should also ensure better current flow.
The tailcap has a second spring, one is on the pill inside the head, ensuring the battery does not rattle, and that the connection is stable and safe.
The MCPB has gold plated contact point on the border.
In hand Shots!
Here is a short in hands video:
Comparison Shots!
Action Shots & Testing
Here is a beamshots gallery done on a hike:
The beam is pretty throwy, the spot is rather on the small side with a generous spill to illuminate a wider area.
The last 4 are the 4 output modes in order low-med-high-turbo
Between High and turbo the Cool White is more noticeable.
Here is also a very short video of the output modes:
Last Words and Conclusions:
I got the flashlight sent by BRINYTE to review, I was not paid for the review, what you read is my honest and personal opinion.
What I like:
- Long battery life
- long throw
- good output without exaggeration
- doesn’t get too “hot”
- good interface
- LED tint is not too bluish besides on TURBO
What I DON’T like:
- Cool White LED is not for everyone, it has low CRI
- rubber boot il filmsy, if it pops out it’s hard to put back
- rubber boot on mine got damaged easily
- nothing else in particular
Other considerations:
- stepless dimming would be nice, instead of 4 preset modes
