Pricing & Availability

FlashlightGo sent me this light in exchange for an honest review. Here is the product page in their store where you can see current pricing.

What comes in the box?

The box is very basic. It’s a generic Weltool cardboard box with just a sticker indicating what’s inside:

• The light itself
• Battery (inside the light)
• User manual
• Spare O-Ring

Notably, no charging cable is included. That’s a good call because most users will probably already have at least one USB-C charging cable.

Design & Construction

This light looks very Weltool. There’s plenty of knurling and texturing for lots of grip. The notches around the head look like they’re for tritium vials, but I’m not sure if vials would actually fit in the slots (9.5mm x 2.1mm x 1.1mm).

Build quality is excellent. Weltool is known for making tanks shaped like flashlights, and this is no exception. The anodizing is more on the matte side, which I don’t typically like, but this is still nice and smooth. It’s not rough and chalkboard-like. Nicely done, Weltool!

User Interface

This UI is sub-par and I don’t care for it.

This light uses a forward clicky mechanical switch. A “click” is a full depression of the switch to the point that it clicks. A “tap” is a quick half-press and release without fully depressing to the point of clicking.

How it works:

• On/Off: Click for constant on or half-press for momentary on. Click again or release the switch to turn it off.
• Modes: It always starts on Medium. Double-tap from off for High mode, or turn the light off and back on again. Half-press five times to access Low mode.
• That’s it: There are no blinky modes like strobe, SOS, beacon, or battery check. No lockout either, but loosening the tailcap a bit works great.

What they got right:

• Double-tap goes to the highest mode. That’s the best way to quickly access the brightest mode on lights with a mechanical switch.
• There’s no mode memory. That’s great on mechanical switch flashlights because it’s consistent. It’s easy and quick to tap-tap directly to the mode you want.
• There are 3 brightness levels. More would be excessive on a light this small and simple. The mode spacing could use some improvement though.

What they got wrong:

• Mode spacing is poor. Low is way too bright at ~30 lumens. Medium is also too bright and too close to High mode. That’s par for the course on AA/14500 dual-fuel lights though. Only single-battery-chemistry lights this size have good mode spacing.
• Low isn’t directly accessible. Lights with a mechanical switch should always turn on in the lowest mode. That way you can access it without accidentally blasting the area with too much light. In this light, you have to tap 5 times to enter low mode. Ridiculous!

Emitter & Beam

According to the product page, this is a “High-Density X-LED”, which is meaningless marketing mumbo-jumbo. My guess is this is a generic round-die domeless LED, similar to the ones used by Olight and Nitecore (branded “NiteLab”) in some of their recent models. The die is miniscule and quite bright so the throw performance is astounding.

I unscrewed the bezel, but the lens (and everything behind it) didn’t want to come out. A small suction cup might be necessary to remove it.

The hotspot is quite narrow for a light this small. It’s very intense and fairly well-defined. The spill is relatively dim but sufficient. This is a great beam for seeing far away or pointing at things, but not great for general utility.

In the beamshots below, camera settings are fixed and the wall is 2.8M away.

In the beamshots below, camera settings are fixed, the basketball goal to the right of the hotspot is 39M away, and the power pole in the center is 185M away.

Mode Chart

Disclaimer: All of my measurements are taken at turn-on. Lumen measurements were taken on a Texas Ace 3.5″ Lumen Tube. A candela measurement was taken at 10 meters with an Opple Light Master III on the highest brightness, and other candela figures were calculated relative to that. CRI, CCT, & DUV data were taken for each mode from a few feet away at the center of the hotspot with the Opple Light Master and Waveform DUV Calculator. Runtime tests were performed with the Ceilingbounce app on my smartphone. These tests were performed with a fully charged included battery unless otherwise specified. I cannot measure moonlight directly, so moonlight readings are calculated based on the brightness relative to the next-lowest mode. None of this is professional equipment, so take these measurements with a grain of salt.

The official specs are above, followed by my own measurements below.

Level	Lumens	Candela	Throw (Meters)	CRI (Ra)	Color Temp. (K)	DUV (Tint)
High	520	25000	316	66	6020	0.0062
Medium	230	11000	210	63	5650	0.0102
Low	31	1500	77	64	5310	0.0121
NiMH High	160	7700	175	64	5590	0.0103
NiMH Med	20	960	62	61	5350	0.0138
NiMH Low	1.2	60	16	60	5280	0.0154

Runtime

Performance is fine. Respectable brightness on High mode and respectable runtime on Medium and NiMH High. I would have liked flatter output.

Thermal regulation: The Turbo and Turbo cooled (desk fan blowing directly on the light) graphs are virtually identical, so there’s no active thermal regulation here. Moreover, there’s no thermal regulation at all, not so much as a timed stepdown. Brightness just follows battery voltage, and it can get quite hot on High mode.

LVP (Low Voltage Protection) is not present. The light relies on li-ion cells to have a built-in protection circuit like the included cell. If you use an unprotected li-ion cell in this light, it may get over-discharged.

Driver & Regulation

Driver: Based on the regulation performance and battery support, I believe this is a boost driver. When on an AA battery, it will efficiently boost the voltage to whatever the battery needs. On a Li-Ion battery, it appears to run unregulated. That’s par for the course with 1xAA/14500 lights. The head is glued on and the driver is covered, so I couldn’t get any detailed photos. It does have a spring.

Regulation performance is poor when running on a Li-ion battery. Brightness on all modes follows battery voltage. It still provides respectable brightness even on a low battery though. I suspect the regulation is much better on an alkaline or NiMH battery, but I only tested with the included cell.

Note: All regulation measurements are taken at turn-on so they do not reflect any thermal or low voltage stepdowns that may occur.

PWM: No PWM is visible to my eyes or camera, nor audible to my ears.

Parasitic Drain: There is no parasitic drain because this light uses a mechanical switch.

Switch

This light has a forward clicky mechanical switch on the tailcap. That means it completes/breaks the circuit instead of just sending signals to the driver, and you can momentarily turn it on by pressing the switch halfway. Pressing it all the way will latch it on/off.

It’s easy to access because it protrudes past the tailcap, but it takes a lot of force to latch it. Since it protrudes, this light cannot tailstand. I like forward clickies and this one’s pretty good.

Carry & Ergonomics

Ergonomics are fine. It’s small so there’s not a lot of surface area, but it’s covered in knurling and machining facets so you can get a secure grip. Both a reverse grip and a cigar grip work, but I find the cigar grip more comfortable since the light is so small.

The clip is simple and well-executed. It’s got some extra bends in the middle for some reason and doesn’t carry very deep. I appreciate that it lands on a smooth part of the head so it shouldn’t tear up your pockets. There’s enough space at the mouth and bend of the clip that thick pockets shouldn’t cause problems. You can remove the clip and put it on the other way for bezel-up carry or clip it to a hat. I like that better than the two-way / bidirectional clips that are popular now but sometimes get snagged on things.

Batteries & Charging

Battery options are numerous, and a suitable USB-C rechargeable 900mAh 14500 cell is included. Any AA/14500-size cell will work. Alkaline, NiMH, lithium-primary, or lithium-ion. You can even use two batteries (except lithium-ion) with the optional extension tube.

Charging is facilitated by a USB-C port built into the battery. The end of the battery glows red while charging and blue when full. Both A-to-C and C-to-C cables work fine.

Competition

Here are some lights in the same class and how they compare.

Convoy T2, T3, and T5: more customization

• dramatically less expensive
• larger
• marginally worse clip
• much floodier beam, better for general EDC utility
• reverse clicky switch (can change modes without turning off, but no momentary)
• many body color options (and even a copper version)
• many LED options

Skilhunt E2A: more utilitarian

• less expensive
• much floodier beam, better for general EDC utility
• reverse clicky switch (can change modes without turning off, but no momentary)
• more color options
• different LED options (cool white, and warm white high CRI)
• bidirectional pocket clip

Lumintop Ant Man: more laser than flashlight

• dramatically more expensive
• dramatically more throw and significantly less lumens
• LEP instead of LED
• tiny pencil beam with no spill, useless up close

This section is not comprehensive. If I didn’t include a particular light here, it doesn’t mean it’s bad or doesn’t deserve to be here. I simply cannot list every possible competitor.

Conclusion

This is a neat light. I like the build quality, clip, switch, and included cell with USB-C charging. I don’t care for the UI, but the switch is good. It’s got the most throw of any LED 14500 tube light by far, so it’s highly compelling for people who want maximum throw in a tiny AA-size package.

Thanks to FlashlightGo for sending me this light for review!
