Lumintop Thor2 v2 Review: LEP Flashlight
Lumintop Thor2 gen 2 specifications
|Brand/model||Lumintop Thor2 v2|
|Max. Lumens||350 lm|
|Max. Beam intensity||738,000 cd|
|Review date||January 2022|
Okay, this time we are reviewing the 2nd gen. Thor II / Thor 2. (I’m reviewing it mainly with the 18650 battery tube, but I also used the 18350 tube from the v1 for testing)
The original Lumintop Thor 2 is an LEP flashlight running on a single 18350 or 18650 battery (if used with the extension tube). The 2nd version of the Thor 2 has the same battery options, but instead of an extension tube, it’s using a dedicated 18650 battery tube.
Having a dedicated 18650 battery tube makes the light look and feel better. I didn’t particularly like how the extension tube looked on the original Thor 2.
Let’s go over a few similarities and some differences.
Both lights look similar, with the same diameter head and the same style tail switch. And both have the same golden-looking ring just below the cooling fins. But the 2nd generation has an o-ring behind the ring, so it doesn’t just fall off.. a smart move, Lumintop.
In terms of appearance, there’s also a few differences. The 18650 battery tube looks much better IMHO, and the head on the v2 has a few cutouts to make it more appealing.
But without looking any further at the external differences, the most significant difference is inside.
The main difference between these 2 is the light source. While the original Thor 2 uses the traditional mirror-style LEP module, the 2nd gen has the backlit / shine-through module. After reviewing a few dozen LEPs, I can tell you from experience that these 2nd gen modules haven’t been as good performers. So, I’m eager to test that and see if this gen2 is using an updated shine through LEP module that can compete with the mirror LEPs.
The flashlight I received is probably a prototype because it didn’t arrive with accessories or a manual. The packaging also didn’t quite look it was a 100% fit. So take this list of contents with a grain of salt because the actual product will include accessories and a 18350 battery tube by default.

There’s no images for the box because it was just a generic box, not made for this light.
Flashlight in use
The Thor II v2 is a relatively short 18650 flashlight with a decent-sized head. I like how the newly designed 18650 battery tube sits in my hands. And because of the lightweight, it doesn’t feel like it is front-heavy or anything.
Lumintop upgraded the battery tube with a different machining pattern, and I must admit that this looks so much better, but it also helps with the grippiness. Unfortunately, the tail switch is built into the battery tube and can’t be removed. And Lumintop decided to keep the lighted switch just for fun. I usually want to turn those things off because they unnecessarily drain the battery. However, the lighted tailcap can be helpful in some cases, so I know it’s not just a gimmick. And I unscrew the battery tube slightly to break the electric connection and turn the lights in the tailcap off.
There’s no pocket clip, but it does have a lanyard attachment ring near the switch. So I assume the actual accessories include a Lumintop lanyard.
Build Quality, and Warranty
I really can’t complain about the build quality. Lumintop’s build quality is generally good, and this particular light doesn’t disappoint either. At least for so far that I’ve tested and played with it.
There are only two parts; the head and body (including the switch. And the threads that screw them together are anodized with enough lubrication and protected by a single o-ring. There’s no second o-ring slot in case you want to add another for increased waterproofness.
Anodization looks good, and I had only two small spots where anno was missing, but that is likely caused by someone testing this out before me. (This was probably Neal himself). It’s a fairly matte finish.
When looking at the driver’s spring I noticed the missing retaining ring. So I checked the Thor 2 v1, which also is missing a retaining ring. That means the driver board is probably kept in place by glue. Not the best solution, but hey, if something works, why try fixing it.
Warranty? I’ll refer to their website: https://lumintop.com/product-warranty/
LEP, Lens, Bezel, Beam, and Reflector
Generally speaking, there are 2 kinds of LEP modules. The classic modules include a mirror, that reflects the blue laser onto a phosphor layer (to change the color from blue to white/yellow) before the photons are concentrated with a convex lens to shine like a ‘normal LED flashlight’.
The second type is the laser shining through a translucent layer of phosphor and then concentrated by a silicon dome and a convex lens to make the beam look like a ‘normal LED flashlight’. This type is considered inferior to the classic modules, but are much more compact.
The previous Thor 2 uses the classic mirror module, but the 2nd gen has the shine-through module, which enables the flashlight to be shorter, but we’ll have to see if this ‘upgrade’ made it outperform the older one.
The bezel can be removed and gives access to the protective lens. This lens is much easier and cheaper to replace than the actual convex lens.
Lumintop also used the same type of turbo glow tubes that are illuminated from the inside. When you turn the light on, these 6 tubes are ‘charged’ and start to glow. The moment you turn the light off, these will glow for a little longer, but not for very long. These are alternatives to the more expensive, and much hard to come by (these days) tritium vials.

Driver & User Interface:
Lumintop changed the driver. Instead of the 3 mode driver of the v1, the driver has changed to a 2 mode with strobe. Maybe there were people who reached out to them to ask for this, but I don’t consider this an ‘upgrade’. But this could just be a prototype driver? I don’t know
- Low, High
- Half-press: nothing
- Single-click: to last used mode, mode memory (except strobe)
- Half-press: switch between Low and High
- Single-click: turn off
- Double tap: strobe
- To High: none
- To Low: none
- To Strobe: none
Blinky modes menu:
- Strobe.. it’s a double tap.
Low battery warning:
- No, just lower output
- Not visible by eye
Strobe is only a double click away, and it’s not uncommon to accidentally activate strobe when switching modes. But when you are calm, and know it has only 2 main modes, this doesn’t have to be a problem. You’ll get used to it rather quickly. It’s just when you try to switch modes 2 times in a row, it can activate strobe, depending on how fast you click.
Batteries & Charging
It seems like the light will be shipped with the 18350 battery setup by default. I’m basing this review mainly on the 18650 battery tube, because that’s how I received mine.
Fortunately, it doesn’t have any trouble accepting any longer 18650 batteries. I tried a very long, protected, button-top Nitecore cell, and it didn’t have any trouble fitting. The flashlight just worked as expected, unlike the Mateminco FW2 I am reviewing at together with this light.
I also used the tailcap of the Thor 2 v1 (which I believe to be identical to the v2, but that’s just my assumption). And I didn’t have any trouble fitting unprotected flat cells, as the longer Weltool 18350 with USB port.
So that’s great news, and you can use any battery you have lying around.
To keep cost low, they probably stayed away from onboard charging.
All output numbers are relative to my homemade Integrating Sphere. It is set up with an Extech SDL400 Lux Meter for measurements including a Kenko PRO1D ND-16 filter. The base measurement is done with a Convoy S2+ that has been tested at 255 lumens.
For Amp readings, I use a Fluke 77III DMM. For higher amps I now use a Fluke 325 True RMS clamp meter. For microamps, I use a cheap DMM with an easy-to-use micro amp setting.
All of my readings were taken from a fully-charged Samsung INR18650 30Q 3000mAh and Keeppower IMR18350 1200mAh.
Measurements were manually taken at the start and after 30 seconds. The 10 minutes reading was taken from the runtime graph.
|Battery||Mode||Amps at start||Specs||@ start||@ 30 sec||@ 10 min|
|Samsung 30Q||Low||0.54||40 lm||58||58||56|
|Samsung 30Q||High||2.89||350 lm||314 lm||297 lm||99 lm|
|Keeppower 18350||Low||0.54||40 lm||58||58||55|
|Keeppower 18350||High||2.86||350 lm||309 lm||297 lm||95 lm|
The runtime test was done with the 50cm integrating sphere, including the Kenko Pro1D ND-16 filter and Extech SDL400 data logging Lux Meter.
High starts at around 314 lumens. After 5 minutes it’s down to 274 lumens when it drops to below 100 lumens. The total runtime is 3h08min.
Low mode starts at 58 lumens and is relatively stable for 2.5 hours. Then it starts to decrease bit by bit until it is 29 lumens at 4h38min, before it abruptly shuts off.
In this runtime I included the runtimes with a Keeppower 18350 battery (1200mAh).
Measurements were taken outdoors at 20 meters with a professional Hagner E4-X Lux Meter.
|High||738,000 cd||752,000 cd||1734||1897||1.08|
My measurements were a bit higher than specs.
But let’s see how it performs against the v1.
Lumintop Thor 2 vs Lumintop Thor 2 gen2
|Mode||Thor 2 v1||Thor 2 v2|
|Med||373,500||(no med mode)|
|High||891,000 cd||752,000 cd|
The v1 has 3 modes, and the lowest mode is lower, and the highest mode is higher.
Here is the graph comparison between v1 and v2
Taken into consideration that the v1 throws farther, and has a higher output, it’s clearly the better of the 2. But in person, that difference may not be as apparent as it is in this graph. Especially if you point it at something relatively close.
LEPs are really only useful at larger distances, 200+ yards.
Here’s a comparison with all the other smaller LEPs we reviewed.
For the following beamshots, I used a Canon EOS 5D Mk2 and a 100mm lens. manual settings: ISO1600, .5sec , F4, 5000K
The first tower is 450 meters / 492 yards away.
I noticed that one of the second set of images shows that the beam isn’t in the same spot as the other. But at 450 meters it’s more sensitive to point at something…

Explanation on star ratings:
1: Avoid: my phone flashlight would be a better choice – 2: Poor: significant defect or issues; almost unusable – 3: Average: some defects or issues; but still usable 4: Good: recommended (minor issues) – 5: Great: highly recommended
4 stars: ★★★★
I honestly think that the v2 looks better than the v1, especially with the 18650 battery tube.
When it comes down to performance, the v1 outperforms the v2. Unfortunately, the v1 is no longer widely available, so the comparison may not be as important if you don’t have one yet. If you already have the v1, I don’t think the v2 is a worthy upgrade. You can still get the 18650 battery adapter though since it looks and feels better than using the extension tube on the v1. If you like the looks of it, and only use it for less than 5 minutes, this is still a good thrower for its size, outperforming many other small LEP flashlights.
