Weltool T1 Pro Flashlight Review
The Weltool T1 Pro is a flashlight using a single 14500 (or AA) cell. It has a Cree XPP emitter and smooth reflector for great throw! Read on!
Official Specs and Features
Here’s a link to the Weltool T1 Pro flashlight product page.
Versions
I believe there’s just one version of the Weltool T1 Pro flashlight.
Price
KillzoneFlashlights.com has the Weltool T1 Pro flashlight in stock now and it’s available for $54.
Short Review
I really love 14500-sized lights and this is a great example of one that sort of “punches outside its category” – it’s very throwy! I like unexpected things, so this tiny light having great throw is a great surprise. The build quality is great (which I’ve come to expect from Weltool). I do not like the way to access low mode, but I can overlook that. Support for both AA (or “1.5V”) cells as well as (the included) lithium-ion 14500 cell is fantastic.

^ Measurement disclaimer: I am an amateur flashlight reviewer. I don’t have $10,000 or even $1,000 worth of testing equipment. I test output and such in PVC tubes!! Please consider claims within 10% of what I measure to be perfectly reasonable (accurate, even).
What’s Included
- Weltool T1 Pro flashlight
- Weltool 900mAh 14500
- Spare o-ring
- Manual
Package and Manual
Build Quality and Disassembly
The design of the Weltool T1 Pro flashlight head is different enough to be special, and I love it. It’s not ‘cooling fins’ but I do think the extra surface area here is sufficient for that. This design feature is also just like the Weltool T2, the big brother to this tiny light.
Build quality is great and robust.
Again, check out this head design!
The tailcap has a nice beefy spring and very smooth, lubricated threads.
The head end also has a spring.
Size and Comps
Size (±0.5mm): (head diameter) 20mm, (barrel diameter) 18mm, (length) 97mm
Weight excluding battery: (±0.5g) 43g
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 my custom engraved TorchLAB BOSS 35, an 18350 light. I reviewed the aluminum version of that light in both 35 and 70 formats.
Retention and Carry
A pocket clip is included and attached by default. This is what I’ve come to call the “standard Lumintop clip” because of how common it was on lights from Lumintop for a while. There’s nothing at all wrong with that.
The clip is a friction-fit clip and there’s a small lanyard hole in the shoulder.
Clip hug!
The pocket clip is reversible but in the other position (bezel up), carry is fairly shallow.
No lanyard or anything else is included.
Power and Runtime
Weltool includes what you’ll need for best performance from the T1 Pro. This is a 900mAh 14500 cell – lithium-ion. The T1 Pro is also versatile – it’s also designed to run 1.5V cells (that is AA: primary or rechargeable.) I love this feature!
The cell is installed in the Weltool T1 Pro flashlight in the usual way – positive end toward the head.
Below are a few runtime tests.
When using lithium-ion cells, low voltage protection is observed at around 3V. With NiMH, output shuts off at around 0.88V.
Charging
While the T1 Pro itself does not have charging, the included cell does. This is by way of a USB-C charging port on the positive end.
Weltool does not include a cable.
Charging works nicely but is a little slow, requiring over 2 hours. C to C charging works just fine too.
Modes and Currents
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens | Tailcap Amps (@4.2V) |
|---|---|---|---|---|
| High | 540 | 38m | 431 | 2.59 |
| Medium | 365 | 1h10m | 291 | 1.21 |
| Low | 86 | 8h42m | 66 | 0.20 |
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens | Tailcap Amps (@1.5V) |
|---|---|---|---|---|
| High | 160 | 39m | 140 | 2.22 |
| Medium | 53 | 3.5h | 37 | 0.22 |
| Low | 31 | 92h | 0.01 |
Pulse Width Modulation
None of the modes on any cell type use 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, 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
A single switch controls the T1 Pro. It’s a mechanical tail switch and is a forward clicky. This allows momentary activation of the light. It’s also what facilitates mode changes.
Here’s a UI table!
| State | Action | Result |
|---|---|---|
| Off | Click | On |
| Off | Repeated taps | Mode advance (M>H) |
| Off | Repeated taps >4 | Low |
| On | Click | Off |
LED and Beam
Weltool uses a Cree XPP emitter in the T1 Pro. That’s a good choice for throw and probably trades a bit of output for that. This emitter is fairly small! I like it quite a bit though.
The bezel is smooth, so light doesn’t escape when on a flat surface (below is not a flat surface…)
LED Color Report (CRI and CCT)
CCT is “fairly good” at around the claimed 5700K. CRI is low, however, at under 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
What I like
- Package includes cell
- Great throw!
- Cell has USB-C charging
- Simple user interface (read it as a “two mode” light that has a “hidden” Low mode)
- The big brother T2 make a good matching set!
- Can use lithium-ion and 1.5V cells
- There’s a long body for using two cells!
What I don’t like
- Having to click 4x to get to low
- Very low CRI
