It’s great to have an LEP flashlight, reaching a mile. But what about the times you need a light to use for close-up work? An LEP beam definitely won’t be the right choice for this, unless you had some kind of diffuser. So how about a combination of LED and LEP ?
That’s probably what Lumintop thought when creating the Lumintop Thor PRO a few months ago. A hybrid flashlight with 2 different kinds of light sources, LED, and LEP. But it was a big and heavy flashlight, one that wouldn’t fit in most pockets. So therefore the new Thor 4 has been introduced.
They are also the brand that has produced most LEP flashlights in the last couple of years. So they were already taking quite a bit chunk of the LEP market. So, are all Lumintop LEP lights great?
Well, let’s find out.
You get the typical Lumintop cardboard box, with the following accessories:
- The flashlight: Lumintop Thor 4
- Battery adapter to use it with 18650 batteries
- USB-A to USB-C charging cable
- 2 spare O-rings.
Flashlight in use
The Lumintop Thor 4 doesn’t have any traditional knurling and it can feel a bit slippery. But I must say, that I quite like the pineapple design!
It’s pretty well made, and the little golden ring also adds to the perceived value of the light.
The switch is easy to find, even with the backlit turned off. (BTW. that backlit button really helps find the switch in the dark).
The flashlight has 3 options for light sources. You can triple-click to toggle between them. 1 is just the LEP, the second is just the LEDs, and the last is a combo of LED and LEP.
Unlike the Thro PRO, the backlight has only 1 color, green. The Thor PRO uses 2 colors (blue and green) and the color shows what light source is currently used. Unfortunately, that is missing on this one. So you can’t really know what light source the light is using. BTW, you can turn the backlight off with 7 clicks.
Having the option to choose between flood and throw (and a combination of both) is really cool. Many people look for 1 flashlight for a specific purpose, for example, camping, hiking, around the house, on a farm, etc. But the Thor 4 has both flood and throw, and is therefore great for many scenarios.
Like all jack of all trades, it’s neither the brightest nor the farthest reaching. But it’s a great all-rounder.
It fits very comfortably in my hand, where my thumb rests on the switch, and my index finger covering the USB-port on the opposite side of the head.
Build Quality, and Warranty
All Lumintop’s LEP lights are named Thor, so it’s not a surprise that they called it the Thor 4, even though it is a hybrid flashlight, and not just an LEP like the Thor1, Thor 2, and Thor 3.
The black anodizing has a relatively matte finish and looks nice. There are no sharp edges and even the fins around the head are chamfered and smooth.
Both, the battery tube and tailcap can be removed, and the threads are anodized. So a short twist will mechanically lock the light out. The o-ring, as well as the threads, are lubricated, so they screw nice and smooth. The battery can be loaded from the front and rear. And I would probably recommend loading it from the front.. why? Because the tailcap is a bit hard to attach when the flashlight is loaded with a battery. You have to tighten it with a bit of force, because the battery sits flush with the rear end of the battery tube, and the spring is sticking out the tail cap.
Warranty according to Lumintop, but if you buy it from Nealsgadgets, contact him instead.
- 30 days free replacement: Lumintop will replace or repair products with manufacturing defects within 30 days of purchase.
- 5 years free repair: Lumintop will repair the products free of charge within 5 years (accessories 1 year, products with built-in battery 2 years)of purchase if problems develop with normal use.
- Lifetime warranty: If repair is required after the guarantee period, we’ll charge for parts accordingly.
- This warranty does not cover normal wear or tear, abuse, force major damage, or defaults by human factors.
LED, LEP, Lens, Bezel, Beam, and Reflector
The Lumintop Thor 4 looks very promising with a maximum output of 2800 lumens with 4 LEDs, and a total reach of 1170 meters.
It has 4 LEDs on 1 side, and an LEP module in the other. So you can have high lumens and flood, or just 100% throw. You can easily switch between just the LEDs for flood, the single LEP for throw, or both of them combined.
Lumintop’s specs mention CREE XPL Hi, which means they are also a bit throwy! But since it uses frosted TIR optics, you still get a pretty smooth beam that can throw.
And because of these frosted optics, you don’t see any artifacts or CREE rainbow colors. Which is really nice. And on top of that, the optics are protected by a glass lens.
The LED beam is cold at the center, with the following measurement in Turbo mode. Please keep in mind these are averages. If you move the flashlight the temperate might be as much as 100 or 200K different. Just saying. Turbo was measured at a 5 meters distance.
- CCT: 5908K
- Ra (CRI): 69.2
- DUV: +0.0030
And now for the Moon mode. This was measured at about 20-30cm from the Opple.
- CCT: 5680K
- Ra (CRI): 68.1
- DUV: +0.0058
The higher the output, the cooler the beam, and the closer to the BBL (which means, the beam is less green)

Driver & User Interface:
Lumintop’s UI is easy to understand and pretty straightforward. And that’s great, especially considering you can choose 3 different mode settings (light sources).
- Moon, Low, Medium, High, Turbo (for LEP, LED, and combo)
From OFF: (this works the same in all 3 light source configurations: Led only, Lep only, Combo
- Single-click: back to last used mode (mode memory)
- Double click: High (another double click would be Turbo)
- Triple-click: switch between LEP, LED and Combo
- Press and hold: moon mode
- 4 clicks: battery check
- 5 clicks: lockout mode (repeat to unlock)
- 7 clicks: turn on/off the backlit switch
- Single-click: turn off
- Double click: Turbo
- Triple-click: switch between LEP, LED and Combo
- Press and hold: cycling from low to high (3 modes only) or when release the switch and press again, it will reverse, from high to low
- To Turbo: double click from On, or 2 times double click from off
- To Turbo momentarily: click 2 times, and hold the second from off to have momentary access.
- To Moon: long press from off
- Yes, a single click from off will return to 1 of the main modes
Blinky modes menu:
- 4 clicks from Off shows the battery level:
- First set of blinks are the Voltage, the second set shows the tenth of voltage. If it blinks 3 times, and then 7 times, it means 3.7V.
Low battery warning:
- Yes, the light starts blinking, and then the side switch keeps blinking.
- Yes, with 5 clicks from off to activate, and repeat for deactivation. When you click the switch while being locked out, the light will momentarily turn on in Low mode. (not moon mode).
- Moon mode has some PWM, and the Opple measurements confirmed that.
Firmware / UI Conclusion:
The UI is nice and easy to understand, and the switching between LED, LEP, and Combo was pretty good and easy. A second switch could also work, but this is
Batteries & Charging
The Thor 4 looks very short compared to other 21700 LEP flashlights, and I really like that. It’s quite compact so you can even pocket carry it.
The Thor 4 uses a single 21700 lithium-ion battery, but Lumintop also included a 18650 battery adapter, so you can use those as well. You can use protected and unprotected 18650 batteries. But if you stick to 21700 batteries, only unprotected cells will fit. Protected 21700 won’t fit!
And unprotected 21700 flat tops fit so snugly, you can’t hear any rattling while shaking.
On the opposite side of the switch you get a USB-C port. Lumintop includes a USB-A to USB-C cable, and but it can also charge with a USB-C to C cable. It charges at about 1.8A with both a USB-A cable as well as a USB-C cable. So no benefits of a C to C cable. While charging, the bunny (in the switch) turns red while charging.
The Thor 4 also serves as a powerbank. It can charge your phone and other devices on the fly. When the powerbank feature is enabled, the bunny turns blue. When trying to charge my phone it was charging at about 500mA, which is not much. But according to the manual it is supposed to be 5V at 2A max.
(Bunny red = charging… bunny blue = discharging).
The output measurements in this review are based on my homemade integrating spheres, each equipped with an Extech SDL400 Lux Meter. For consistency and accuracy, a calibration light (Convoy S2+ with 249lm and a Convoy S2+ with 261lm) is measured prior to each set of lumen measurements.
For high-output lights, one of the lux meters uses an ND camera filter to prevent the lux meter to max out. This is either the Kenko PRO1D ND16 up till about 80,000 lumens or Gobe ND32 for anything above.
Most of the readings were taken with a fully-charged Samsung INR21700 50G.
All Turbo, High, and Medium modes, and didn’t recharge between Moon and Low.
I manually measured the output at turn on, and after 30 seconds. the 10minutes measurements were taken from the runtime graph.
|Mode||Specified||at Turn on||30 sec||10 minutes|
|Moon||1 lm||1 lm||1 lm||–|
|Low||75 lm||52 lm||52 lm||51|
|Med||500 lm||420 lm||415 lm||400|
|High||1050 lm||989 lm||961 lm||414|
|Turbo||2800 lm||2676 lm||2407 lm||419|
Also measured with Samsun 21700 50G
|Mode||Specified||at turn on||30 sec||10 minutes|
|Moon||60 lm||62 lm||61 lm||59 lm|
|Low||70 lm||80 lm||78 lm||76 lm|
|Med||130 lm||151 lm||148 lm||144 lm|
|High||220 lm||231 lm||224 lm||113 lm|
|Turbo||280 lm||248 lm||259 lm||249 lm|
LEP + LED combined Lumens:
|Specified||Measured at turn on||30 seconds||10 minutes|
|Moon||60 lm||63 lm||61 lm||–|
|Low||120 lm||128 lm||126 lm||121 lm|
|Med||330 lm||558 lm||545 lm||528 lm|
|High||1150 lm||1133 lm||1055 lm||251 lm|
|Turbo||2750 lm||2329 lm||2086 lm||231 lm|
I also tested it with a 30T, just to see how much brighter it would be. I could only readh 2360 lumens at turn on, but it did maintain a higher brightness after 30 seconds of 2286 lumens. So, a high drain battery will have better performance.
- Couldn’t measure
The runtime tests were done in the 50cm home made integrating sphere, combined with the Extech SDL400 data logging Lux Meter.
|LED Mode||Specified runtime||Measured runtime (ANSI FL1)||Time till shut off|
|Low||20h||34h 32min+||34h 32min+|
|Med||3h 55min||4h 55min||5h 37min+|
|High||3h 41min||4h 47min||*5h 13min+|
|Turbo*||3h 30min||3h 06min||*4h 46min+|
I stopped all runtimes early, because the output was very low, and I had no idea how deep it would discharge. With some tests I let it run for a couple more hours, but they kept running. * this is the runtime the light dropped to a sub 10 lumen mode..
Low mode was supposed to run for 20 hours.. After 34 hours I stopped the test, because it was still at 23 lumens, and could possibly run for a day longer.
I haven’t tested Moon mode, which was according to the manual 40 days, which I don’t trust either. None of the specifiec runtimes make much sense! Typical Lumintop!
|LEP Mode||Specified runtime||Measured runtime (ANSI FL1)||Time till shut off|
|Moon||10h||7h 23min||7h 23min+|
|Low||8h||6h 15min||6h 15min+|
|Med||3h 50min||3h 33min||3h 33min+|
|High||3h 40min||4h 21min||4h 21min+|
|Turbo*||3h 08min||3h 54min||3h 54min+|
I don’t know what happened with the Low mode and Turbo mode, that it turned off for a second.
Also, it’s interesting to note that once the batteries run really low, the Thor 4 turns to Moon, LED mode.. and continues running for a long time…
LEP + LED Runtimes
|Mix Mode||Specified runtime||Measured runtime (ANSI FL1)||Time till shut off|
|Low||6h||5h 21min||5h 21min+|
|Med||3h 30min||2h 06min||2h 06min+|
|High||3h 21min||4h 05min||4h 22min+|
|Turbo*||3h 15min||1h 13min||4h 11min+|
I didn’t do a moon-mode runtime
Lumintop Thor 4 throw measurements
LEP measurements were taken outdoors at 20 meters, and LED measurements indoors at 5 meters with a Hagner E4-X Lux Meter. Recorded 30 seconds after turn on. I also tested LEP indoors to see if they were close to the numbers outdoors, and they were very close.
|Turbo (LEP)||342,000 cd||356,000 cd||1193||1305|
|High (LEP)||–||316,000 cd||1124||1230|
|Med (LEP)||–||218,400 cd||935||1022|
|Turbo (LED)||10,200 cd||6,500 cd||161||176|
|High (LED)||–||2,650 cd||103||113|
|Med (LED)||–||1,200 cd||69||76|
The LEP performed better than specified, but the LEDs performed quite a bit worse.
The first few beamshots are with a 50mm lens. Shed is about 65 meters away.
For the throw 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.

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: ★★★★
The Thor 4 is filling a gap in between LED and LEP flashlights. And not just a gap, it fills the gap pretty well. It’s relatively short, and fits in your pocket. It’s the only hybrid light that fits in your pocket, relatively comfortably. Others are either much bigger, or have sharper edges etc.
It performs pretty well in terms of maximum beam distance. But unfortunately, the LED part leaves a bit to desired. It doesn’t have a regulated output, and the specified runtimes are incorrect.
The UI is quite a bit better than some of its competitors, and it’s pretty easy to understand. You just have to keep in mind that you can increase modes and decrease modes at the same time. But I’m pretty sure you can get used to that.
