   This flashlight has a long distance of illumination. It’s got fantastic battery life, many built in features like different levels and flash patterns. It weighs an average amount for its size. It would be great for viewing a yard from the porch. At the price, it is probably the best flashlight you can get. It is pocketable, but has a belt holster which is very multifunctional. Excellent price for the performance. Very sturdy build quality.

Let’s see if it meets that claim. Package: The PT28 comes in a large box for a flashlight, but it has to be in order to hold all the accessories that come with it. There’s a picture of the light on the front, highlights on the sides, and detailed specifications on the back. Included in the package are: Brinyte P28 Brinyte-branded 3100mAh protected 18650 battery Spare o-rings Lanyard Manual cards Proprietary magnetic USB charging cable Holster Tactical ring Flashlight in use, and use cases: The light is easy to hold, though it’s large for an 18650, coming in at longer than 26650 and 21700 lights. The tail switch is easy to activate and is forward-clicky, meaning that you can half press it for momentary light. The side switch is also easy to use when changing brightness levels, though it’s flush with the body and hard to find by feel, unless you have a physical point of reference, like the clip or tactical ring. To install the tactical ring, unscrew the tail cap and slip the ring on over it. There are small grooves on either side of the tail cap that correspond with ridges on the inside of the ring to guide it on in the proper orientation and prevent it from moving. The ring is rather large, but this will accommodate wearing gloves during use. It doesn’t tail stand well due to the small posts on the end of the tail cap, and having the ring on unbalances it, making tail standing harder. The clip is nowhere near deep carry, but it seems to hold the light securely. You’re likely not going to pocket this light anyway, given its size, so that’s ok. Build quality, and warranty The PT28 is solidly made from aluminum with black or tan anodization. It has rectangular knurling on the head and tail while the body is mostly smooth except for a design similar to the Brinyte logo. The tactical ring is also smooth. The head has protrusions on either side which is where the side switch and magnetic charger port are, and opposite that are the flashlight’s name and the Brinyte logo. You can only remove the tail cap, as the head and bezel are glued on, and the tail threads are not anodized, so mechanical lockout is not possible. When I took the tail cap off, I noticed the brass retaining ring for the tail switch spring was rather tarnished. Same with the spring on the head end of the light. These things don’t affect performance, but are visually deterring. Since there are springs on both ends, the PT28 can accept a number of 18650 sized cells. The PT28 is covered by Brinyte’s standard warranty: 30 day replacement and 2 year repairs. See their website for full details. The LED, lens, bezel, reflector, and beam Brinyte chose the Cree XHP35 HD for this light, specifically in 6500K. This is a cool white, domed, 3V, 3.5mm² LED designed for maximum output. The emitter is paired with a deep, smooth reflector for increased throw and housed behind anti-reflective glass and a slightly crenulated bezel. The beam has a tight white hotspot with yellowish,usable spill. While it’s not going to affect things at range, there is some greenish tint shift towards the edge of the spill, and a purple halo from the AR glass. This type of light values raw output over quality of light, and you can see that in the readings from the Opple Light Master Pro. I measured a maximum of 7500K, actually, instead of the 6500K reported. Either way, it’s very cool. CRI came in at below 75 and DUV was an average of 0.0020 above BBL which is to be expected with this emitter. Dimensions and size comparison with its competition Dimensions: Dimension Millimeters Inches Length 140.4 5.52 Head diameter 28.5 1.12 Body diameter 25.2 0.99 Weight: Weight Grams Oz. Without battery 109 3.8 With battery 157 5.5 The tactical ring adds another 19g/0.7oz. This light is big for an 18650 light, in both length and weight. That in itself is not a bad thing, but it’s something to keep in mind. User Interface and Driver Available modes: Low, medium, high, turbo Available blinky modes: Strobe User interface: From OFF: Side switch: Nothing Tail switch: Click: On Half-press: Momentary on Half-press, click: Strobe Two half-presses: Momentary strobe From ON: Side switch: Click: Advance mode Double click: Strobe Double click: SOS Tail switch: Off Mode memory: The light will stay in the last used non-strobe mode when you turn it back on.

Strobe/blinkies Strobe: Two half-presses of the tail switch from off or double-click the side switch from on. SOS: Double-click the side switch while in strobe. Lock-out mode: None? PWM None visible. Batteries and charging The PT28 comes with a Brinyte branded 18650 lithium ion battery. This battery has over charge/discharge protection circuitry and a button top which make it 3.6mm longer than a standard 18650. However, because of the springs on both ends of the tube, the PT28 can accept other 18650s. Brinyte also advertises that you can use two CR123A batteries, but I do not have any to test. A capacity test with my Vapcell S4+ charger at 250mA reported 3059mAh of capacity, just under the advertised 3100mAh. Still pretty good. The PT28 also has onboard magnetic charging, which is convenient, however, the magnetic charging cable is proprietary. I don’t know of any magnetic charging systems that are not proprietary, but this is still an annoyance. If anything happens to that cable, you’re either going to have to ask Brinyte to sell you another one, or take the battery out and charge it on a regular Li-ion battery charger like with other lights. The magnetic charger just sticks to the side of the light without any other retention, so it’s very easy to accidentally disconnect. If the light even rolls on its side, the charger will fall off. One concern I had was that since the charging surface is flat, how does the magnetic charging cable know not to deliver power if it magnetizes to another piece of metal that’s not the flashlight? The low voltage protection performs well, cutting off the light before the battery gets too low. The lowest I measured after a full discharge was 2.63V which is on the low side of things, but still ok. Charging the light from there took an average of two hours and fifteen minutes, which is pretty good. At the end of charging, the battery measured 4.16V each time. Performance To obtain these numbers, I used a very rudimentary integrated shoebox and ceilingbounce on my Samsung Galaxy S10. Ceilingbounce has been calibrated to match the specs of the Baton 3 as provided by Olight and corroborated with other reviewers. Lumen measurements This light outperformed specs on every mode, even at 30 seconds. It makes me wonder if Brinyte deliberately undersold this light, but maybe it’s better that way, so that you don’t disappoint. Turbo step down: 1min 42s Mode Specs Lumens @turn on Lumens @30 sec Lumens @10 minutes Low 10 13 13 13 Medium 60 71 71 71 High 360 403 400 395 Turbo 1600 1722 1670 440 Battery Life: Runtime graphs Again, the PT28 outlasted specified runtime on every mode with medium having the greatest difference at 34% over. Very good runtime overall, and very nice regulation. The amount of light it puts out is the same right up until it shuts off. Mode Specified runtime Measured runtime (ANSI) Time till shut off Low 98h – – Medium 16h 21h 33min 21h 33min High 3h 30min 3h 33min 3h 33min Turbo 1min, 1h 50min 1min 42s, 2h 22min 9h 06min ANSI FL1 standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turning on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries. Peak beam intensity and beam distance measurements The numbers for candela were obtained with a UNI-T UT383S luxmeter at 5 and 15 meters, then averaged. Again, meets and exceeds specs. That’s quite some throw for a relatively tube-shaped light. Mode Specs Candela measured Meters Yards Low – 75 17 19 Medium – 475 44 48 High – 2950 109 119 Turbo 15,200 16,300 255 279 Extra info: Peak beam distance according to ANSI FL1 standards: The calculated value of distance in meters at which the flashlight produces a light intensity of 0.25 lux. (0.25 lux is about the brightness of a full moon shining on an object). The columns Meters and Yards show rounded numbers. Beamshots As you can see in the picture, the PT28 has a large hotspot and a decent amount of spill. This should be very usable. Pros and Cons PROS Full package with battery, onboard charging, and accessories Very good output, runtimes, and regulation Exceeds all specifications CONS Magnetic charger easy to knock off Long On the heavier side Slight tarnishing on some internal retaining parts (cosmetic only) Final Verdict + review score Overall, the Brinyte PT28 “Oathkeeper” keeps its oaths, coming in above all specifications with the exception of battery capacity, and even that’s very close. If you like to play at tactical games, the included tactical ring and body size make that a possibility, though due to the size, this is one for your bag instead of your pocket. I give it a 4.5 for meeting almost all specifications, but having a little bit of a challenge with the magnetic charging. ——————————- Explanation on star ratings: 1: Avoid: a match would be a better choice 2: Poor: significant defect or issues; almost unusable 3: Average: some defects or issues; but still usable 4: Good: recommended (minor issues) 5: Great: highly recommended (3.5 would be average but probably would buy, 2.5 below average, and wouldn’t recommend buying it) Disclaimer: This flashlight was sent to me for review at no cost by Brinyte. I have not been paid to review, nor have I been holding back on problems or defects.
