Wurkkos TS11S Rechargeable Flashlight Review

The Wurkkos TS11S rechargeable flashlight is a nice entry to the simple category of light! It has incredible throw and uses one 18350 cell. Read on for testing!

Official Specs and Features of the Wurkkos TS11S rechargeable flashlight

Here’s a link to the Wurkkos TS11S rechargeable flashlight product page.

Versions

There’s only this version. The package can be bought with or without a cell, though.

Price

Without an 18350, the Wurkkos TS11S rechargeable flashlight costs $29.99. The cell adds only $2, so that’s a no-brainer addition!

Short Review

I love these little throwy flashlights; this is a great example! The Wurkkos TS11S rechargeable flashlight throws incredibly! I like the small size, and that the cell only adds $2 to the already low cost. The simple user interface is great, too!

^ 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’s Included

• Wurkkos TS11S rechargeable flashlight
• Wurkkos 1000mAh 18350
• Charging cable (USB to USB-C)
• Spare o-rings (2)
• Lanyard
• Manual

Package and Manual

 

Build Quality and Disassembly

The build quality here is great.  Really not much more to say about it than that –  The whole product is a high-quality package.

Both the head and tailcap have springs. On the head end are the same threads – in fact, the cell tube is reversible. There’s no good reason to do that (since there’s no pocket clip to attach to the body) but there’s a good reason to not do that. If you reverse the cell tube then the little battery icon is backward!!

Size and Comps

Dimension: 89.5mm (length) x 40mm (head diameter)
Weight: 90grams (without battery)

If the flashlight will headstand, I’ll show it here (usually the third photo). If the flashlight will tailstand, I’ll also show that (usually in 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.

Also above is the light beside a new standard 18350 light! It’s not one I’ve reviewed yet but this is the CWF Arcadian Peanut in aluminum. This one is stonewashed and has the new Quantum Dragon driver – a whole new product! Stay tuned for a full review of this tiny powerhouse!

Retention and Carry

A lanyard is included for carrying the Wurkkos TS11S rechargeable flashlight. This lanyard attaches only through the tailcap hole.

Nothing else is included for carry or retention. Not ably, there’s no tailcap magnet. (Which isn’t a problem, just noteworthy because of the tailcap having the appearance that many magnet tailcaps have.)

Power and Runtime

A single lithium-ion cell powers the Wurkkos TS11S rechargeable flashlight. The proper size is 18350, and one can be included with your purchase if you opt for that package. The cell is a button-top 1000mAh 18350 and is not special or proprietary, or customized in any way (except the nice Wurkkos wrapper).

The cell goes into the light in the “normal” way – the positive end toward the head.

In case you forget the direction, and you have the cell tube installed correctly, you can regard this little battery icon on the cell tube for a reminder!

Below are a few runtime graphs.  I did not observe 2000 lumens out of this 6000K-6500K version. I’m recording at 30 seconds, which is well after the significant stepdown. The initial output is around 1000 lumens, which is still well short of the 2000 claim. The thermal management feature is very active, as you can clearly see in the charts below.

Low voltage protection is observed. The light didn’t always shut off, but the switch indicated in every case that the voltage was low, as follows:

Green: >30% power
Red: <30% power
Red Flashing: Power level is critical

Charging

Another feature of the Wurkkos TS11S rechargeable flashlight is built-in charging. There’s a USB-C port in the head, which has a press-in cover. This cover is quite thick, and when installed properly, very secure. It has a thick edge and must be pushed deliberately into the opening.

An appropriate charge cable is included. It’s USB to USB-C.

When charging, the switch flashes red and turns green when charging is complete.

Here’s a graph of C to C charging. Charging looks quite good!

Here’s a charge graph with the USB to USB-C setup. It’s fairly normal, and charges at around 1A. The cell should handle that easily.

 

Modes and Currents

Mode	Mode Claimed Output (lm)	Claimed Runtime	Measured Lumens	Tailcap Amps
Turbo	2000	1h	1032 (0s) 785 (30s)	7.54
High	900	1h20m	371	2.10
Mid	300	1.5h	161	0.83
Low	10	29h	10	0.04
Moon	1	275h	0.33	[low]

Pulse Width Modulation

There is PWM on all modes except Moon and Turbo. On all but the lowest output level, it’s not PWM that I can call “noticeable.”  It’s plenty fast PWM.

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, which 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 switch seen on the is an indicating e-switch. It is a soft and low switch with a translucent center and edges that can be red or green.

Unlike the some other Wurkkos lights, the TS11S does not use Anduril. I think the idea was to give users a non-Anduril version of a very capable light, and Wurkkos accomplished that! However the light does still offer ramping, so you still have plenty of options.

Here’s a UI table according to the manual! In practice, I was unable to access Group 2, the ramping modes. (That’s perfectly great for me since I don’t want ramping, particularly since this light has enough output levels. But the manual should be addressed, probably.) Note that’s the same thing I said about the Wurkkos FC13s and it’s still true – I’m unable to access the ramping setting on this light!

State	Action	Result
Off	Click	On (Mode memory)
Off	Hold	Moon
Any	Double Click	Turbo
On	Hold	Group 1: Mode advance (Eco>Low>Mid>High) Group 2: Ramp up (or change ramp direction if held within 1.5s of being held and released)
On	Click	Off
Turbo	Click	Return to previous level
Turbo	Double Click	Group 1: Group 2: Iterate between Moon and Turbo
Any	Click 3x	Strobe
Strobe group	Double Click	Strobe advance (Strobe>SOS>Beacon)
On	Click 4x	Switch between Group 1 and Group 2
Off	Click 4x	Lockout
Lockout	Click 4x	Unlock to on state (Mode Memory)
Lockout	Click	Two blinks to indicate lockout

LED and Beam

Wurkkos uses a Luminus SFT40 emitter in the TS11S. It’s rated at 6000K-6500K. The emitter is coupled with a big TIR.

LED Color Report (CRI and CCT)

CCT stays roughly in the range of what Wurkkos claims – 6000K to 6500K. The CRI is low, though, at around 70.

Beamshots

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 Wurkkos TS11S rechargeable flashlight

What I like

• Great value
• Cell included for $2!
• 5000K emitter option (and they’re a little warmer than that, too!)
• Indicating e-switch is a novel variety
• USB-C charging works well

What I don’t like

• Could not access the ramping modes mentioned in the manual
