Lumintop Thor 1 Review: LEP Flashlight
Lumintop THOR1: manufacturer’s specifications
|Brand/model||Lumintop Thor 1|
|Beam intensity||342,000 cd / 1200 meters|
|Review date||July 2021|
Since 2020, the flashlight world has seen a large increase in LEP flashlights. LEP flashlights are flashlights that have no LED or Incandescent bulb, but a laser as its source of light. LEP stands for Laser Excited Phosphor and basically means that the laser beam shines through, or shines unto phosphor to change the color and characteristics of the beam. It’s no longer a pencil beam like you see with laser pointers, but a beam that is more similar to the traditional LED flashlight.
A much more intense beam that can reach over 1000 meters with ease. Unlike LED flashlights, an LEP flashlight doesn’t need to have a large reflector to reach that far. Even a flashlight with a head diameter of 1.5 inches, it is able to reach 1000 meters/ .6 miles.
Right now we are looking at one of the few 18350-based LEP flashlights on the market. And although its name (Thor 1) would suggest it to be the first of a series, the Thor 2 was actually released before the Thor 1. If you’re interested in seeing what its sibling has to offer, check out our Lumintop Thor 2 review.
Unfortunately enough, I didn’t receive the original box of the Lumintop Thor 1, and mine was sent in a standard grey cardboard Lumintop box. There were no accessories or even a manual included. If you order yours, you should get all the accessories.
Flashlight in use
Although its design looks a lot like the Jetbeam E1 we reviewed, it looks kind of interesting. Its body has a pineapple style knurling that looks the same as the E1, which again is a copy of the very old pineapple design flashlight from about 15 years ago.
Due to its design, the Thor 1 is easy to hold and operate. It’s currently the shortest LEP flashlight on the market. The reverse-clicky switch is located at the rear of the light and contains a dim multi-color LED indicator. As far as I can see it uses 3 colors; green, red and blue. Unscrewing the tailcap doesn’t help to turn them off because they are bare aluminum. If you want to turn them off, you have to remove the battery.
The Thor 1 can be unscrewed in 2 locations. At the rear, the tailcap can be removed to insert the battery, and the front shouldn’t be unscrewed. If you unscrew the front, you’ll get access to the LEP light source, but possibly mess up its focus. At least it’s nice to know that it doesn’t include any glue.
There’s no pocket clip or lanyard attachment so you either need a pouch, holster or carry it in your pocket. This must be the first pocketable LEP flashlight that I know of.
Tail standing doesn’t work because of its protruding switch.
Build Quality, and Warranty
The silver Thor 1 almost looks titanium, but in reality, mine is raw aluminum. There are vertical lines on the bezel part (head) of the flashlight that have clear machining marks.
Its pineapple-style design looks smooth without any sharp edges and looks much smoother than the lines on the head.
Unscrewing the tailcap feels very, very smooth since they applied a decent amount of lubrication. There seem to be 5 full rounds of threading. And just like its bigger sibling, the Thor 1 also has some golden-looking rings for aesthetics.
Inside the tailcap is a single spring, as well as on the driver’s side. Since both ends use a spring, you can use flat tops and button-top batteries.
I haven’t opened the front yet, since I want to do the tests first. I will open it up after I am done testing.
Lumintop gives you a very generous warranty: 30-day free repair/replacement for manufacturing defects, 5-year limited warranty for manufacturing or quality defects for flashlights, 2 years for built-in batteries, 1 year for batteries, and lifetime limited warranty that covers repairs, but not parts and labor.
LEP, Lens, Bezel, and Reflector
There’s something to the Lumintop Thor 1, that most others don’t have. And that’s the inability to see anything useful through the front lens, except if you hold the lens about 1 cm from your eye. Then you can see that the Thor 1 is using the ‘newer’ LEP design. I am referring to the shine-through LEP setup, where the laser is located behind a translucent piece of phosphor through which the laser shines. There is a silicone dome on top of that phosphor to make the beam spread out more.
The beam is then focused into a narrow style beam via a convex lens.
There’s no real bezel on the Thor 1. The front/bezel/head is all made of 1 piece of aluminum. You easily unscrew the head to get to its internals in case you want.
Shining the beam on a white wall will clearly show several bright rings around the corona/spill of the Thor 1. This is only visible up close, and the farther away the beam hits the wall, the less visible it gets. After about 5 meters, you won’t see the rings anymore.
When it comes to the beam color, I’m glad to say it’s pretty ‘white’. Many other LEP flashlights I reviewed had yellow, or even greenish beams. But the Thor 1 seems to have a very ‘whitish’ beam, and probably one of the whitest beams I have seen on any LEP flashlight.
Dimensions and size comparison
The Thor 1 clearly excels in terms of dimensions. It’s currently the shortest LEP flashlight on the market.
- Length: 96.6 mm / 3.8 ”
- Head diameter: 32 mm / 1.26 ”
- Body diameter narrowest point: 25.6 mm / 1 ”
- Empty: 103.7 g / 3.66 oz
- With 1200mAh keeppower battery: 127.3 g / 4.49oz

Driver & User Interface:
The simpler the better is my opinion when it comes to dedicated flashlights. The Thor 1 has a very simple, and straight forward UI. With the mechanic reverse-clicky switch, the UI is just like most other flashlights.
- Low, Medium, High
- Single-click: to last used mode, mode memory
- Double click: off
- Half-press: Cycle through the menu from Low to High
- Single-click: off
- Yes, it will activate after about 3 seconds.
Blinky modes menu:
Low battery warning:
- No. You have to remove the battery to stop any current flow.
- Possible, but can’t really see it with my eyes
Firmware / UI Conclusion:
The UI is extremely simple, which is a good thing. The more Anduril based lights I have to review the most I prefer simple UI’s that don’t have messed up temperature configurations etc.
Batteries & Charging
With springs on both ends, the Thor 1 has no problem using flat top or button top batteries. If you don’t have any 18350 batteries yet, look for the Keeppower 1200mAh, that have a high discharge rate and high capacity.
I’ve used to test my 18350 lights with some 700mAh Efest batteries that were several years old. I recently upgraded to a couple flat top 18350 batteries from Keeppower and I’m a happy camper.
I also tried a long 18350 battery with USB port and had no trouble using it. So you can use any 18350 you have lying around. They should all fit and work without problems.
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.
All of my readings were taken from a fully charged Keeppower IMR18350 1200mAh battery. Keep in mind we are looking at an LEP flashlight and not a regular EDC or Tactical flashlight that have much more power. The Thor 1 is made to throw far, not to light up an entire room.
Amps were measured with a Fluke 77III, at the tailcap.
|Low||0.39 A||30 lm||26 lm||33 lm||37 lm|
|Med||0.88 A||150 lm||122 lm||132 lm||138 lm|
|High||3.16 A||400 lm||107 lm||323 lm||349 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. The battery used is a Keeppower IMR18350 with 1200mAh.
Medium starts off at 138 lumens and slowly drops to about 80 lumens in 1 hour and 1 minute, when it drops to sublumen output.
Low starts at around 37 lumens and the quickest drops is in the first 30 minutes down to 20 lumens, and from then onward it slowly decreases till almost 2 hours. From that point it starts decreasing quicker till 2 hours and 22 minutes when it turns off.
Measurements were taken outdoors with a professional Hagner E4-X Lux Meter.
|High||356,000 cd||1193 meters||1305 yards|
Specs show a max beam intensity of 342,000 cd, and mine was a bit higher than that.
Here is the runtime chart with candela, compared to other small (18650 and 21700) 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.

4.5 stars: ★★★★⋆
Not everybody is pleased with its design, but as the shortest LEP flashlight, it definitely deserves a mention on your shopping list. The Thor 1 has a very simple UI which makes it an easy-to-use flashlight that everybody can get used to within a matter of seconds.
The Lumintop Thor 1 is definitely the best thrower for its size.
