Nextorch P91 Flashlight Review
The Nextorch P91 flashlight features four cool white emitters that offer very high output. It has USB-C charging and a dual-switch interface, too! Read on!
Official Specs and Features
Here’s a link to the Nextorch P91 flashlight product page.
Versions
There’s just one version of the Nextorch P91 flashlight. Nextorch frequently iterates lights, and a very similar design can be seen in the P83. They are quite different lights, though.
Price
MSRP and the going price for the Nextorch P91 flashlight is $119.99. It’s available through my referral link, here.
I also have a referral coupon for Nextorch.com that’ll give you 10% off! The code is “ZEROAIR“.
What’s Included
- Nextorch P91 flashlight
- Nextorch 4800mAh 21700
- Lanyard
- Charging cable
- Manual etc
Package and Manual
Build Quality and Disassembly
The Nextorch P91 flashlight has a good heft and is a nicely built light. It has a nice heft in hand and overall just feels like a good quality light.
The tailcap has a nice beefy spring, and the threads are fairly short and do not have anodizing.
Inside the cell tube, you can see that the head also has a spring.
Size and Comps
DIMENSIONS: 160mm x 36mm x 28.5mm
WEIGHT: 165g (without battery)
If the flashlight will headstand, I’ll show it here. If the flashlight will tailstand, I’ll also show that here too!
Here’s the test light with the venerable Convoy S2+. The version below is a custom laser-engraved Convoy S2+ host by GadgetConnections.com. I did a full post on an engraved orange host right here! Or go straight to GadgetConnections.com to buy your Convoy S2+ now!
In the photo above, you may note that the SRM (standard reference material) flashlight for comparison has changed! I used a TorchLAB BOSS 35 for ages. Now, what you can see as the 18350 SRM is the Hanko Machine Works Trident. While I have not reviewed or tested the Gunner Grip version seen here, I have tested a Hanko Machine Works Trident Total Tesseract in brass. I love the Trident, and it’s a striking contrast next to the inexpensive Convoy S2+, which also makes a great standard reference material.
Retention and Carry
The Nextorch P91 flashlight has a nice friction-fit pocket clip that attaches only to the tail end. This clip isn’t designed as a “deep-carry” clip but due to the length of the light, it does function that way.
The clip has a nice design, including a stamped logo near the shoulder. This is just a standard friction-fit clip – it lacks the “keyed” and “captured” clip design seen on Nextorch’s more tactical lights (like the TA21).
A lanyard is also included. You could attach that through the pocket clip, but these two holes in the tailcap are a much better option.
Power and Runtime
Nextorch includes a single 21700 cell with the P91 flashlight. It’s a 4800mAh cell and has a button top.
The cell goes into the Nextorch P91 flashlight in the normal orientation – positive end toward the head.
Below are three runtime tests. I didn’t see 5000 lumens, but the light does hold over 4000 lumens for a good few seconds. Output on the lower modes is very steady for nearly the whole runtime duration.
The light does shut off with low voltage protection but there’s also an indicator on the body beside the switch. This indicator also lights for a few seconds when the light is turned on, as follows:
Four blue: 75-~100%
Three blue: 50-~75%
Two blue: 25-~50%
One red: 10-~25%
One red flashing: 0-~10%
Charging
Charging on the Nextorch P91 flashlight is via USB-C. This charging port is in a nice but unusual spot – it’s hidden behind some threads in the head and is normally completely covered.
There’s a little USB charging logo on the side. Honestly if not for this, it’d be hard to get any idea that there’s even built-in charging on this light! That’s not a bad thing; it’s a nice and stealthy bonus feature.
Nextorch includes a short USB to USB-C charging cable.
Just like when using the light, this LED array does indicate the charge level.
Charging seems to go at a “range of currents” instead of an absolutely steady current. I don’t know that it’s really a bad thing, but it sure does make for an ugly chart. Either way, it takes around 3.75 hours to fully charge.
Modes and Currents
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens | Tailcap Amps |
|---|---|---|---|---|
| Turbo | 5000 | 1h45m | 4185 (0s) 4176 (30s) |
16.93 |
| High | 1100 | 2h45m | 942 (0s) 940 (30s) |
1.67 |
| Medium | 350 | 8h | 336 | 0.52 |
| Low | 45 | 60h | 40 | 0.05 |
Pulse Width Modulation
PWM is not observed on any of the modes of the P91 flashlight.
Here you can see a “baseline” – a chart with almost no light hitting the sensor.
Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.
User Interface and Operation
The Nextorch P91 flashlight uses two switches. It’s an unusual (and sort of “opposite”) setup. The tail switch seems to be an e-switch. It has two stages and seems to be momentary-only.
Next is the switch on the body near the head. This feels like a mechanical clicky. It offers momentary and mode changes after the light is on, though, so it’s more likely a very clicky e-switch, too.
Here’s a user interface table!
| State | Action | Result |
|---|---|---|
| Any | Half press tail switch | Momentary turbo |
| Any | Full press tail switch | Momentary strobe |
| Off | Tap side switch | Momentary low |
| Off | Click side switch | Low |
| On | Tap side switch | Mode advance (LMHT) |
LED and Beam
Nextorch doesn’t say what the four emitters in this P91 are. They do not have a dome, so they’re “High Intensity.” They look quite a bit like Cree XHP35 HI, but lack the bond wires (so I would guess they are not XHP35 HI). Each emitter has a little orange peel reflector.
Above you can also see the strike points on the bezel for glass breaking.
LED Color Report (CRI and CCT)
Despite being very high output, the CCT stays fairly reasonable. It’s cool, to be sure, but peaks at around 6200K. CRI is “low to very low” – under 70.
Beamshots
These beamshots always have the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level, and the beam hits the ceiling around 9 feet away.
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. These photos are taken around 18 inches from the door.
I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!
Summary and Conclusion
The Nextorch P91 flashlight is a very high-output light with an interesting switch setup as well as USB-C charging. The tail switch makes it reasonably tactical.

^ Measurement disclaimer: Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.
What I like
- Great build quality
- Includes 21700 (standard)
- Very high output
- Good switch setup (for tactical, maybe less so for EDC)
What I don’t like
- Price is way up there!
- Low CRI
- Fairly quick stepdown
