Lumintop Thor II Review: LEP Flashlight
Lumintop Thor 2 specifications
|Brand/model||Lumintop Thor 2|
|Beam intensity||769,500 cd|
|Battery config.||1*18350 (or18650 with optional adapter)|
|Review date||June 2021|
I can’t keep count on the number of Lumintop flashlights we reviewed, but I must say that they were all very interesting to review. Starting off with the extremely popular Lumintop BLF GT (giga thrower) a few years back. Ever since Lumintop started working together with the community, they have been adding more and more awesome, and interesting new flashlights onto the market.
But instead of a high power flashlight, we are currently reviewing a long-range flashlight that can hit 1,800 meters. If you think that means high-power, you’re wrong. Even by specifications, it is supposed to only produce 500 lumens, and I can guarantee that it’s not even reaching that.
We’re looking at the Lumintop Thor II, Lumintop’s first LEP flashlight. LEP stands for Laser Excited Phosphor, which is likely the next big thing in the flashlight industry. And the following 2 things are different with the Thor II over its competitors: its design and price.
Most Lumintop’s flashlights arrive in a pretty simple brown cardboard box with some the manufacturer’s name, logo, and a drawing of the flashlight on the outside. On the inside, there isn’t really much to see because the package is very basic and simple.
- The flashlight: Lumintop Thor II
- 18650 battery adapter (optional)
Yes, those 3 things. I’m okay with that, if that keeps the price down.
Flashlight in use
The flashlight is supposed to be a 18350 type flashlight and can be used with a 18650 battery when you use the optional battery adapter.
Its design is rather futuristic, with minimal knurling. This doesn’t mean it’s slippery because it has enough ridges and cutouts, that it helps with grip.
In terms of operating the Thor II, you have 1 switch at the rear. This is used for power and mode-switching and it’s a reverse-clicky switch. This means that it will turn on after the click, and you can change modes without turning the light back off. A forward clicky switch would mean you have to turn the light off to change modes.
Around the switch is a translucent ridge with mixing colors of light which is lit when you tighten the different parts. These LEDs will pull a very small amount of current, so they shouldn’t be too much of a problem in terms of battery usage, but I still don’t like to use my battery when a flashlight is turned off. There is currently no way of turning these mixing lights off, but it does help you locate the flashlight in a dark room very easily.
Although there is not lanyard included in my package, there’s still a lanyard attachment point on the tail cap. Oh, and because the attachment point is located on the side of the tailcap, it will stail tail-stand without problems.
Build Quality, and Warranty
I’m not really good at describing flashlight designs and terminology that comes with it. So I’d love to just point to the following pictures to have a look.
Threads on the adapter and tailcap were pretty dry at arrival. Some people don’t like that, but let me tell you this is better than having dirty lube on the threads that seep into the flashlight when it gets hot. You can use your own lube to make the threads screwing like butter.
There’s some knurling on the optional 18650 extension battery adapter.
Here’s what Lumintop has to say about their warranty:
30-day free replacement: LUMINTOP will replace a new product within 30 days of purchase for any manufacturing defects if problems come into being in normal use; We will replace it with the same model. If the model has been discontinued, customers will receive a product with a similar or improved model.
Five-years free repairs: LUMINTOP will offer free repair within 60 months for lights from the date of purchase if the problem develops with normal use.
Lifetime warranty: If repair is required after guaranty period, we’ll charge for parts accordingly.
LEP, Lens, Bezel, and Reflector
The Thor II is an LEP (laser exited phosphor) flashlight so no reflector or LED is used. The Thor II is still using the traditional LEP module that is using a mirror to direct the blue laser onto the phosphor. The beam that is being produced is then bundled via a convex lens.
If you point the beam to a wall within 10 feet away, you’ll see that the center of the beam is darker. This is totally normal and will disappear when you shine at things farther away.
Since there is no reflector, Lumintop decided to add trit-look-a-likes in the head. These aren’t tritium vials but some sort of glow tubes. Only green glows very briefly, and the blue and red tubes don’t do anything.
When you look at the front, Lumintop was wise enough to add a glass lens in front of the convex lens. It’s much harder to replace a convex lens with the right focal length than a cheap glass lens. I noticed something interesting with the front lens. It has a tiny black dot in the middle, and I have no idea why it is there.
Behind the lens, on the inside of the bezel, is some glow-in-the-dark added that gives it an even more futuristic look. The bezel has the same color as the rest of the flashlight and is probably made of aluminum. Also, on the side of the bezel is a text warning about the Class 3B laser inside. This doesn’t have to be a problem, but it’s better safe than sorry.

Driver & User Interface:
We’re used to seeing Anduril firmware in many Lumintop flashlights, and I’m glad to say, they didn’t include it in the Thor II. The UI is very easy to use, and the average Joe should be able to get used to it within a matter of minutes, without being afraid to accidentally activate some kind of hidden mode or lockout.
- Low, Medium, High
- Half-press: doesn’t do anything, it’s a reverse-clicky switch
- Single-click: to last used mode, mode memory
- Double click: nothing
- Half-press: Cycle through the menu from Low to High
- Single-click: turn Off
- Yes, it memorizes the last used mode
Blinky modes menu:
Low battery warning:
- When the battery runs low, the light start blinking.
- None, it uses a mechanical reverse-click switch
- Not visible
Batteries & Charging
I’m not 100% sure, but I think Lumintop tried to keep the cost down, and skip several things, and 1 of them being a built-in charging system. That would have added research time, research cost, and probably production cost as well.
There are 2 springs on both ends, so you can use flat tops and button tops, and protected and unprotected batteries, both in the 18350 size as the 18650 size. I tried one of my longest batteries, a Fenix 18650 with USB port, and it didn’t have any trouble.
All output numbers are relative for my home-made 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.
All of my readings were taken from a fully-charged Samsung INR18650 30Q 3000mAh (pink).
Amps were measured with a Fluke 77III, at the tailcap.
|Mode||Current in Amps||Specs||@30sec||@start|
|High||3.26 A||500 lumens||324 lumens||328 lumens|
- There is a LED in the tailcap, that pulls between 0.6mA and 0.9mA, depending on the color of the light. This shouldn’t be a problem, but I don’t like to keep it running indefinitely. I will just unscrew the body so it doesn’t pull any current.
The runtime test was done with the 50cm integrating sphere, including the Kenko Pro1D ND-16 filter and Extech SDL400 data logging Lux Meter.
Lumen runtimes aren’t as important for LEP flashight, because they are built to throw. But to learn more about certain stepdowns, it’s still very important IMHO. Here are the runtime graphs in lumens, and the candela runtimes are in the next section.
The numbers are based on the use of a Samsung INR18650 30Q, 3000mAh battery.
High drops exactly at 5 minutes from about 305 lumens to roughtly 120 lumens. This output continues till the 2 hours and 35 minutes mark when it drops to roughly 20 lumens. This is the time you should replace the battery. The light turns off at 3 hours and 1 minute.
Medium is relatively stable, but not exactly stable till it drops from about 110 lumens to roughly 20 lumens at the 2 hours and 38 minutes mark.
Low is also pretty stable, not exactly a straight line either, but it’s about 30 lumens give or take. Total runtime is 6 hours and 36 minutes. Not too bad.
Next is a 18650 compared to a 18350 battery.
Total runtimes based on a Weltool UB18-129 1200mAh 18350 battery:
High starts off the same and drops the same. But total runtime is of course much shorter. At 55 minutes it drops from from roughly 100 lumens to roughly 13 lumens, and turns off at the 1 hour and 5 minutes mark. The total runtime for High is 55 minutes.
Medium runs for 1 hour and 4 minutes starting off at around 134 lumens down to 100 lumens. It then drops to 14 lumens which continues till it turns off at the 1 hour and 14 minutes mark. The total runtime for Medium is 1 hour and 4 minutes. You still get 10 more minutes to replace your battery.
Low starts off at around 38 lumens but soon drops slowly till about 28 lumens for 2 hours and 10 minutes when it starts to reduce output slightly till it reaches 15 lumens at 2 hours and 35 minutes, when it suddenly turns off. The total runtime for Low is 2 hours and 35 minutes.
Measurements were taken outdoors at 20 and 30 meters (after 30 seconds from turn on) with a professional Hagner E4-X Lux Meter. The battery used was a Samsung INR18650 30Q. From measurements in the integrating sphere there was basically no difference in High mode between a 18650 and high amp 18350 battery.
|Mode||Specs||Measured in candela||in meters||in yards|
|High||769,500 cd||888,000 cd||1,885||2,061|
|High (30m)||769,500 cd||891,000 cd||1,888 meters||2,065 yards|
Since one of the manufacturers reached out to us about our testing methods, I included a 30-meter measurement. When you look at the total candelas, it’s not a big difference, but measuring at 30 meters does have higher numbers. But since I do 20-meter measurements with all long-range flashlights, I’d like to stick with that. 30 meters is more difficult to measure, because there is less time to find the hotspot (because you need to walk 30 meters), and it’s more difficult to aim the hotspot in the middle of an object (I don’t use a wall for this, but a piece of wood/large box.
Here’s the Thor 2 against other LEP flashlights in terms of candelas.
You can see it clearly outperforms all smaller LEP flashlights on the market.
But compared to the larger LEP flashlights, it doesn’t perform as well. So it sits right in between the 2 types of LEP flashlights.
For the following beamshots I used a Canon EOS 5D Mk2 and a 100mm lens. manual settings: ISO1600, .5sec , F4, 5000K
The tower is about 450 meters / 492 yards away.
Disclaimer: This flashlight was sent to me for review at no cost by Lumintop. I have not been paid to review, nor have I been holding back on problems or defects.
- One of the most affordable high-quality LEP flashlights
- Reaches very, very far for a 18350 flashlight
- Unique design
- Glow in the dark tailcap for fancy looks
- No accessories were included like a lanyard, spare o-rings etc.
- I’d prefer a dedicated 18650 tube over a 18650 battery adapter
Explanation on star ratings:
1: Avoid: my phone flashlight would be a better choice – 2: Poor: significant defect or issues, much better options available at the same price – 3: Average: some defects or issues – 4: Good: recommended (minor issues) – 5: Great: highly recommended
5 stars: ★★★★★
There’s nothing really negative to say about the Thor II unless you are not a big fan of its design. But you can’t say it’s not performing well, because that is surely not true. With its 18350 size, it’s currently the shortest LEP flashlight on the market! And therefore also the best 18350 LEP currently for sale.
