Physical description

Semi gloss anti scratch finish, slick design for easy access operation, no aggressive knurling but I prefer this kind as it appears innovative and up to date design. machining is flawless. just by the first touch, you will feel its a quality made right away.

CREE XHP35 LED with maximum lumens of 1600 of cool white tint. NOTE the Alloy aluminum reflector for better reflection.

Springs are on both positive and negative terminals and are gold plated for better current flow and shock resistance during fall or recoil. you can clearly see the threads are square for durability and smooth function and to avoid wear , rubber O-ring is also provided and well lubed for better waterproof performance.

This is the magnetic charging port where you attach the magnetic charging cable,notice all the curves,and machining were done flawlessly.

The bezel is a non aggressive design but obviously adds up an appeal.

The aluminum tactical ring is removable and can be reattached easily by removing the tail cap.

I like how they made the pocket clip in color black as well, the clip tension is decent to ensure you will not lose your light when it is clip in your pocket or belt.

The end part of the braided charging cable will light as soon as connected to any USB port to confirm electric flow to the charging port of the PT18 is secured.

The SIDE SWITCH is also remaining battery indicator and will light up when charging is in progress.

All the markings were nicely done, perfectly centered and clearly visible.

Tail cap button was designed with the Brinyte logo on it, making it even more pleasing. and the side flaps with the hole for lanyard and are protruding and longer than the rubber switch so the PT28 can tail stand.


User Interface (UI)

The PT28 can be operated using the two(2) switches. ( Tail Switch and the Front switch) and is very easy to operate with no complicated instructions to memorize.

Tail Switch- This is the main switch of the PT28, it controls ON and OFF

-MOMENTARY: Half press the tail switch for momentary ON, release to switch the light off.

-CONSTANT ON: Fully press the tail switch until it clicks for constant ON, press again to turn the light off.

-STROBE: Access the strobe directly by half pressing the tail switch twice (2x) quickly


Front Switch- This controls the different brightness levels, and you can also access the STROBE and SOS with the front switch.

When the light is ON, press the front switch to cycle between brightness levels. NOTE the sequence below:

LOW-10 lumens (5880 minutes)

MEDIUM-60 lumens (960 minutes)

HIGH- 360 lumens (210 minutes)

TURBO- 1600 lumens ( 1 minute prior to step down)

When the light is OFF, press and hold the front switch and press the Tail switch all the way to access the LOW mode (10 lumens :5880 minutes) directly.

-STROBE and SOS: when the light is ON in any brightness level, press the front switch twice quickly to access the strobe, press the front switch again twice to access the SOS after the strobe, press the front switch once then the last used level will be activated again.

As always, this is from my own personal experience with this light and any views and thoughts are from my personal opinion, yours may be far different. but I promise to be always honest on my thoughts.

Straightly telling, the PT28 is one of my favorite tactical and emergency flashlight for every day carry, it's slick design and body profile with the tactical ring attached or detached, it will surely serve its purpose on being a reliable illumination companion.

I personally like the design and functionality, the only things that I can criticize with the PT28 are the SOS and bezel design,

SOS: for that being said, SOS should be always at the brightest level when activated as it is a signal that has to be notice at all time when used. but surprisingly its not on the PT28, I think its only on the MEDIUM level so I wish that the brand will address this issue on their next models.

Bezel: this is not a big issue as this will fall into a personal preference, I just wished that Brinyte made the bezel design even more tactical and a little more aggressive.

But overall rating, just like my PT18, I always get fond of my PT28, easy and practical to operate, appealing and there is always with a Brinyte's product, once you get a hold on it, you will feel how solid it was built.

although I cannot say anything further about how durable it will be, but sure is it will be, as my PT18 still works without any issue since 2019.
