Today I have in the Pro version of a light many people already reviewed. This is the Brinyte PT18 Pro, an 18650 light with a Cree XHP35 HD, designed for long weapon use. I have a few optional accessories, which you’ll see below.
Official Specs and Features
There are two body colors of the PT18 Pro – this Desert Tan version and a black version. There is the original PT18 of course, which looks to be largely the same as the Pro, with some changes in charging setup.
This light is selling for $135.
This is a nicely built light, with some cool accessories, and nice weapon mounts. It’s a little on the expensive side, but does seem to meet the claims made by Brinyte.

Package and Manual
That inner black box is hard to get out of that outer blue sleeve.
Here’s a pdf manual, too.
I also received a couple of accessories with my package, and they shipped in this box below.
Build Quality and Disassembly
Build quality is good. Nothing surprising or bad, but it does feel like a solid light.
There’s a lot going on to consider this a weapon light. There’s three switches and a magnetic charge port…. I’m not saying the light isn’t suited for weapon mount; I didn’t shoot any with this light mounted.
As there should be, there are springs on both head and tail of the light.
There’s also a tactical ring included on the light from the factory. It’s removable.
Without the tactical ring and the tactical finger loop, the tail end looks like this:
Without the tactical ring and with the tactical finger loop, the light looks like this. The finger loop really requires the tactical ring, or it’ll flop around.
The black bezel unscrews easily and cleanly, leaving a light that can be used without the strike bezel completely. I didn’t remove this any further, but the bezel is held in by a retaining ring, too.
Size and Comps
The light is 164mm x 25.4mm (body) x 41mm (head), and weighs 170g without the cell.
Retention and Carry
There are a number of ways to carry the PT18 Pro. First is the nylon pouch, which has a spot for the tailcap to protrude from the top. There are also elastic cell holders on both sides of the holder. Below, the left photo has a cell in place.
The light can shine out the bottom of the holster, too.
Also included is a friction fit pocket clip. It’s not anything too special, and would work ok on a belt.
Another thing that’s included is the tactical finger ring. It’s keyed so it fits in only one orientation, which is good because the tail switches will always reliably be in the same place.
There’s also a lanyard which attaches using a metal clip, and would be best on the hole in the tailcap (seen above).
In my accessory pack, I received the two items below. On the left, you can see a weapon mount.
Here’s all sides of that item.
Power and Runtime
I tested the light with the included 3100mAh 18650, which is a standard button top.
Turbo steps down after solid minute, and essentially meets the claim made. The initial intermediate stepdown offers around 1450 lumens for almost 5 minutes, which is respectable. Eventually the light does stepdown very far, and while it’ll click back up to high, steps down to low almost immediately. The side switch is offering a red flash warning at this point, too.
Here’s a runtime on High. Unfortunately the temperature logger stopped during this run, but it was fairly uneventful anyway.
Another thing about operation- when the light is switched on, the indicating side switch displays approximate cell capacity, as follows:
Constant green: 100%-70%
Constant orange: 70%-30%
Constant red: 30%-10%
Flashing red: <10%
Here’s the magnetic charge cable. It’s a proprietary connection on the light, but the USB side is normal. The cable is braided and quite nice.
It connects to the side of the light, and the connection is nice and snappy. I don’t love that this is proprietary but at least the cell isn’t proprietary. It can still charge normally in a slot charger.
During charging, the indicating switch is constant red. When charge is complete, the switch is constant green. The charge cable also has an indicator but it’s mostly just a locator beacon – always blue. And it’s bright blue too.
Charging is as follows. Quite fast, at around 1.8A.
Modes and Currents

Pulse Width Modulation
For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor. And here’s the worst PWM light I have ever owned. Also one of the very first lights I ordered directly from China!
And just for fun, here’s strobe.
User Interface and Operation
There are three switches on the PT18 Pro. First are the tail switches – one proud mechanical switch, and one “side” e-switch. Normally a paddle switch would be there but this is just a proud angled e-switch.
Also on the light is an indicating e-switch on the head end. That spot in the center can indicate red, orange, and green.
Here the switch can be seen in green.
Also an option for operation is a remote pressure switch, which replaces the two switch tailcap.
When mounted, it looks like this:
This switch is neat and works well.
There are three switches. Brinyte names them as follows: Tail primary switch (TPS) (the bigger, proudest switch). Tail Side Switch (TSS) (the oblong switch on the tailcap angle.) And finally, the Front Side Switch (FSS).
This image shows full operation with just the two tail switches.
This image shows full operation with the tail power switch and the front side switch.
Here’s a UI table! I’m not sure the table can be comprehensive… I find that image above to be a little confusing, actually.
|TPS Off||Click TPS||On (Turbo)|
|TPS Off||Click TSS||Momentary Strobe|
|TPS Off||Tap TPS||Momentary Turbo|
|TPS On||Click TSS||Mode advance (LMHT order)|
|TPS On||Hold TSS||Strobe|
|TPS Off||Click FSS 3x||Lock – indicated by two flashes of main emitter. Does not lock tail switches!|
|Lock||Click FSS 3x||Unlock|
|Lock||TPS on for >5s||Unlock|
|TPS Off||Click FSS||Turbo|
|On||Click FSS||Mode Advance|
|On||Hold FSS (>1s)||Off|
|TPS Off||Hold FSS||Low|
|On||Double Click FSS||Strobe|
|Strobe||Double Click FSS||SOS|
|TPS On||Click FSS||Mode advance (LMHT order)|
|TPS On||Double Click FSS||Strobe|
LED and Beam
The emitter here is a Cree XHP35 HD, which is the same as was used in the PT18 (not pro). The reflector is deep and smooth.
The removable strike bezel allows light to peek out.
These beamshots are always with the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right.
I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!
What I like
- Comprehensive package
- Good output

What I don’t like
- The UI can be overwhelming, but generally functions like you’d expect it to
- $135 is high, but maybe not too high
