Note: The above parameters are measured using the measurement method described in the international test standard ANSI/NEMA FL1 using a Brinyte 21700 5000mAh battery under laboratory conditions. The tested parameters are approximate values and may vary with different battery or different usage environment.
Brinyte ZT40 comes in a Premium package. It came in a cardboard box with a nice and hard zippered case inside. ZT40 is protected in its seat by a molded plastic.
In the box I found:
- The Brinyte ZT40 flashlight with Clip and Tactical Ring inserted
- A Brinyte 21700 5000mAh rechargeable battery
- USB-C charging cable
- Lanyard
- 2 x spare o-rings
- Manual and Warranty
The Steel Clip, inserted under the tactical ring, remains firmly in place and allows the ZT40 to be easily inserted into jeans. The Clip can be used to attach a lanyard if necessary.
Brinyte ZT40 has excellent build quality like the previous PT16 tested and reviewed previously. It is built in aluminum alloy with military grade hard anodized finish. Good thicknesses as well as materials and rounded edges. It can be held and gripped well in the hand thanks also to the knurled body. ZT40 is 149.5mm long.
On the Brinyte ZT40 the writing, of good workmanship, is easy to read. On the flashlight it is clearly stated that mine is a model not for sale. Above the writing BRINYTE ZT40 we find the writing USB-C with two arrows that show us the opening direction (counterclockwise) and closing of the protective ring of the (retractable) USB-C charging port. Brinyte ZT40 is IPX-8 certified for protection against water and dust.
On the opposite side of the charging port we find a Status LED that gives us information about the remaining charge level and the status of the battery being charged. I would have preferred the LED in a different position to be able to see it even with the charging port protection ring closed.
Once the ZT40 is turned on, the LED lights up for five seconds to indicate:
• Green: Charge equal to or greater than 70%
• Orange: Charge between 30% and 70%
• Red: Charge equal to or less than 30%
• Flashing Red: Charge equal to or less than 10%
In my tests, the battery was fully charged in about 3 hours (max 2A). The flashlight cannot be used while charging.

Note: during the charging process the ZT40 cannot be turned on.
The battery, included in the package, is a rechargeable 21700 5000mAh lithium. Brinyte ZT40 also works with other 21700 button top batteries.
As contacts with the battery we find a spring both on the negative and positive for better contact with the battery and optimal current circulation. The threads on the torch body are not anodized. Unscrewing the tailcap by one turn still obtains the mechanical block. You can also see an O-ring for protection from dust and liquids.
Brinyte ZT40 is equipped with adjustable focus, which allows you to easily switch from a beam angle of 6° to one of 70°, to meet both long-range lighting needs and those of diffused lighting.
The adjustment can also be done with one hand, with the thumb, thanks also to the grooves on the head. By turning the head clockwise, you obtain an extension of the same, bringing the beam from flood to spot.
Brinyte ZT40 features a new and special TIR lens with the SFT-25R CW LED in the center. The lens, unlike what we find in almost all round dome zoom torches, has a convex part in the center probably to better concentrate the light beam in spot mode. The bezel, of a decent thickness, protects the glass of the ZT40 being slightly crenulated and protruding. Unscrewing the bezel and removing the lens provides easy access to the LED.
The maximum light output is 1,650 lumens with a maximum illumination depth of 490 meters.
Brinyte ZT40 features single tail switch “Forward-Clicky” for complete UI management with 2 light modes; High and Low. The round rubber tail button also has Momentary-On function.
The choice of Brinyte for this model, with only two light levels, is certainly due to the use for which it is recommended, hunting. In the Brinyte catalog we find, for the ZT40, the remote pressure switch that allows you to vary the brightness from 2% to 100%.
The user interface is simple; one click to turn the flashlight on High. Then one click to turn it off and, if you want the low level, another click to turn it back on with the Low level. This sequence must be done by acting on the tail button continuously (within approximately 5 seconds).

BEAM and RUNTIME:
The beam of the Brinyte ZT40 has a cold CW color with an effective zoom. The flood beam is wide and bright while zooming in spot the beam is well concentrated with an excellent throw.
The lens system, which the ZT40 has, does a good job of producing a beam with small visible aberrations and a rounded spot. The spot is white in the center while the crown surrounding it is yellowish. I did not notice any PWM in all levels.
The candela (cd) values found by me with the LX1330B Luxmeter are largely higher than those in the table. In SPOT with the High level I reached a distance of over 600 meters. The low level, in Spot, is perhaps still too bright with its 26100cd (323 meters).
SPOT High/Low: 92340cd/26100cd
FLOOD High/Low: 1935cd/540cd
The focused beam proved to be very narrow and bright. In the photo below it was placed side by side with the Ledlenser MT10 also with the focused beam.
With the OPPLE Light Master Pro, an inexpensive and fairly precise device (even if not calibrated) I made some measurements taking the value of the CCT color temperature and the Ra color rendering. The Flicker is in the green band not at risk. As shown by the values reported, the color of the beam has a CRI index that is not particularly high but average with a cold color of the beam especially in the highest brightness levels.
HIGH Flood Level 1650 lumens, CCT= 7814 – Ra = 74 Duv: -0.0042
HIGH Spot level 500 lumens, CCT= 7886 – Ra = 73.2 Duv: -0.0020
LOW Flood Level 500 lumens, CCT= 6688 – Ra = 72.2 Duv: 0.0010
LOW Spot Level 134 lumens, CCT= 6282 – Ra = 69.6 Duv: 0.0052
With a thermal imaging camera I detected how the heat is distributed on the Brinyte ZT40 in High mode (500 lm) after 1min, 3min and 10 minutes from switching on. Good heat distribution on the whole body. Brinyte ZT40 has a thermostatic module that automatically adjusts the brightness based on the operating status of the torch and the external temperature.
Runtime:
The runtimes performed with the Brinyte ZT40 at the HIGH Spot (500 lumens), LOW Spot (134 lumens) and HIGH Flood (1650 lumens) levels, were done in a closed environment with a temperature of about 25°C. The battery used is the one found in the package, a fully charged Lithium 21700 Brinyte 5000mAh.
I would like to emphasize that the values expressed in the graphs must be taken as a reference especially because they were made with means and environmental conditions different from those used by the parent company in the laboratory.
In the graph below we see the runtime by putting the Brinyte ZT40 in spot mode with High and Low brightness. As can be seen from the graph, the times declared by the company for the two brightness levels were respected. Good regulation.
In the Spot High mode after switching on there is a sudden drop after 2 minutes and 30 seconds. After a short ascent the brightness remains constant until about 2 hours and 30 minutes from the start before starting the descent due to battery exhaustion.
In Spot Low mode the brightness is constant for about 4 hours from the start before starting the descent due to battery exhaustion.
Putting the Brinyte ZT40 in Flood High mode (1650 lumens) has a sudden decrease in brightness after 2 minutes and 30 seconds. After that, the brightness remains constant for about 140 minutes from start before starting to decrease due to battery exhaustion.

CONCLUSIONS
Brinyte ZT40 is a quality zoom flashlight, well built and powerful.
I have reviewed other Brinyte flashlights and this latest ZT40 has also convinced me. I particularly appreciated the excellent brightness with both the flood beam and the concentrated (spot) which according to my tests reaches the theoretical distance of 600 meters.
The zoom system can be operated even with one hand, furthermore Brinyte ZT40 comes with Clip and tactical ring already mounted for good portability.
ZT40 is powered by a 5000mAh battery equipped with a USB-C charging port, included in the package, furthermore I have used other 21700 format batteries with the button without problems.
In the duration tests (runtime) ZT40 reaches and exceeds the values declared by the parent company with a good regulation. On the downside, there are only 2 light levels with the LOW level being too bright when used with the focused beam.
In conclusion Brinyte ZT40 is a high-performance product recommended especially for hunting or for tactical and search operations.
Thanks for reading the review.
