Thrunite Catapult V6 SST70 Flashlight Review
Thrunite has a nice update with the Thrunite Catapult V6 SST70. USB-C charging, a very throwy emitter and the great Desert Tan color. Read on!
Official Specs and Features
Thrunite Catapult V6 SST70 Versions
Only one emitter option exists for the Thrunite Catapult V6 SST70. That emitter is available in three body colors, though. Black, Desert Tan (seen here), and “Metal Grey” are available.
These are available on amazon at the moment, and that’s a good place to get them. The black body comes in as the least expensive, at $74.95. Both the other two are around $5 more, at $79.95. Here’s an amazon referral link that’ll get you to the right place to buy the Thrunite Catapult V6 SST70 now!
This is an exceptionally worthwhile update to the Catapult V6. Throw on this model is down just a little bit (under 10%) but that’s fairly meaningless at 700+ meters. More importantly, this emitter pumps out high lumen numbers and does it well. Maybe I’ve changed too many diapers, but I have to say, I really love the Desert Tan color, too. All in all, this is a nice light!

Package and Manual
Build Quality and Disassembly
First off, the V6 SST70 is essentially the same as the V6 I previously reviewed (years ago!) There are minor but important updates, but overall the look and shape are the same.
The threads on the tail end are unanodized, sort of long, and square cut.
You can see below the tailcap spring – it’s extremely beefy.
On the head end is a different setup. The threads here are anodized, much shorter, and also square cut. I’d recommend separating the parts as seen below for cell swaps.
The cell tube is directional.
As with many (most? all?) Thrunites, there’s a brass button on the head end.
Size and Comps
Officially 138mm (Length) x 58mm (Bezel Diameter) x 33.5mm (Tube Diameter). This is ever so slightly longer (maybe 5mm) than the previous V6.
The weight without a cell is 203g.
If a light will headstand, I’ll show it here (usually the third photo). If a light will tailstand, I’ll show that here, too (usually the fourth photo).
Here’s the test light with the venerable Convoy S2+. Mine’s a custom “baked” edition Nichia 219b triple. A very nice 18650 light.
And here’s the light beside my custom engraved TorchLAB BOSS 35, an 18350 light. I reviewed the aluminum version of that light in both 35 and 70 formats.
Is this the shorty thrower we all want??
Retention and Carry
A nylon pouch is included. The light will only go one direction – tail down. The pouch is good quality.
Also included is a lanyard, which attaches on the tailcap through the hole below.
Power and Runtime
The Thrunite Catapult V6 SST70 has a working voltage: 2.75V-4.2V. In my experience, the light shuts off at around 3.1V. That’s great. Might not suck every gram of energy out of a cell, but I like it anyway.
The light doesn’t prefer protected or unprotected, and works with flat or button top cells equally. What it does need is a cell capable of providing very high output. Turbo draws nearly 10 amps.
As usual, the cell fits with the positive end toward the head.
This Luminus SST-70 really blisters out the lumens – this is over 3000 lumens from a single emitter and sustained over 2600 lumens for minutes. Even after that (and same on High mode), the output for 80 minutes of around 1500 lumens is very good.
The switch indicates as follows:
Blue: 21-100% capacity (3.3-4.2V)
Red: 11-20% capacity (3-3.2V)
Flashing Red: 1-10% capacity (2.8-3V)
Off: 0% capacity (0-2.8V)
Onboard charging is still a feature of the Catapult series. This one offers USB-C charging. The charge port has a press-in cover.
A USB to USB-C charge cable is included.
I tested with both a USB source and a USB-C source. Both work fine, and really look practically the same.
Modes and Currents
|Mode||Mode Claimed Output (lm)||Claimed Runtime||Measured Lumens||Tailcap Amps|
Pulse Width Modulation
No PWM on any mode is seen here!
For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor. Also, here’s the light with the worst PWM I could find. I’m adding multiple timescales, so it’ll be easier to compare to the test light. Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, with is 50 microseconds (50us). 10ms. 5ms. 2ms. 1ms. 0.5ms. 0.2ms. In a display faster than 0.2ms or so, the on/off cycle is more than one screen, so it’d just (very incorrectly) look like a flat line. I wrote more about this Ultrafire WF-602C flashlight and explained a little about PWM too.
User Interface and Operation
The Thrunite Catapult V6 SST70 has a single switch. It’s a side, indicating, e-switch. The indicator is a small circle in the center. I love that the switch cover on this model is black. It seems to match the aesthetic very well, but also provides a great contrast to the brown body, making the switch that much easier to find.
The switch doesn’t sit too proud, and has fairly low travel, but is positively clicky. It’s not a hollow click though, and not too loud. The switch feels like actual metal, and the rubber part under the switch is replaceable.
Here’s a UI table!
|Off||Click||On (Mode Memory)|
|On||Long Press||Mode Cycle (LMH)|
I appreciate the simple nature of this UI, but I do wish the indicating side switch was more heavily utilized. Namely, I think every light with indicating switches should have a battery check feature. Every light with indicating switches. Every of the lights.
LED and Beam
Probably the biggest update to the Catapult V6 is this emitter. It’s a Luminus SST-70 in “cool white.” And it is cool white, but it’s really not that bad of a cool white.
There’s just one emitter here, and it’s really a fairly small footprint. Couple that with the smooth and deep and wide reflector, and you get pretty good throw!
LED Color Report (CRI and CCT)
As I said, this is a cool white emitter. Any of the lower three modes are well under 6000K, which is fairly acceptable. After that, and unsurprisingly, the CCT tends toward a cooler level and is above 6000K. On all modes though (maybe particularly the lower level), the Duv is positive (which means there’s a bit of a green tint).
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!
Conclusion on the Thrunite Catapult V6 SST70
What I like
- Both output and throw meet the specifications
- Charging at 2A is suitably quick for this 5000mAh cell
- UI is simple (and very “Thrunite-consistent”)
- Update to USB-C charging is welcome
- I love the Desert Tan!
What I don’t like
- UI lacks any real battery check
- Not available in NW
