Nitecore has another in the Multi-Hybrid GTS series of lights out. This is the “25” – MH25GTS. It’s a medium range thrower, with a bit of a tactical flair. It has on-board charging, and a dual switch interface too!
There’s only one version of the MH25GTS.
This light is $110 at nitecorestore.com.
This is a good light, but a bit long. Charging takes a long time, but is stable and has a good profile.

Package and Manual
Nitecore’s standard package!
Here’s a pdf of the manual.
Build Quality and Disassembly
No complaints about the build quality of this light. It’s pretty standard Nitecore quality.
The knurling is a little grippier, which will be good for gloved use.
The head has adequate cooling surface area, too.
The insides are the same as the other MH GTS series light I reviewed, the MH12GTS. Since charging is through the tailcap, there’s a little bit of fancy electronic bits to facilitate that.
Also because of the charging, there’s an inner sleeve in the cell tube. This tube can’t be removed without removing the cell tube from the head, which I found to not be possible. (Maybe it’s glued).
Both the head and tail have thick, long springs. This would confirm the belief that this would make a good tactical light.
Size and Comps
Length 150 mm / 5.9 in
Head Size 34 mm / 1.33 in
Weight 124 g / 4.37 oz
The Convoy S2+ is not a short light, and the MH25GTS dwarfs it. Of course it has a different feature set, but still, it’s unreasonably longer.
Retention and Carry
Nitecore includes a standard nylon pouch. The light fits primarily bezel up.
The lanyard attaches on the tailcap, or on the tactical ring. The pocket clip also has holes which would allow lanyard connection.
And finally, the pocket clip. This attaches only on the tail end of the light, (and the cell tube isn’t reversible). It’s a friction clip, and leaves almost two inches of tailcap sticking out of the pocket.
In the photo of the pocket clip below, also note: the tactical ring is removable (and removed here), and the charge port cover isn’t staying in.
Power and Runtime
The MH25GTS is powered by a single 18650 cell, which is included. This is a quality cell, labeled the “NL1835HP” and claims 3500mAh, with a max discharge of 8A. Button top or flat top and protected/unprotected cells should work fine in this light. (It’s also possible to run this light on 2 × CR123 ,2 x RCR123.)
On Turbo, the output initially hits around 1700 lumens (short of the claimed 1800) and at 30s drops down to around 1600 lumens. At 4 minutes, the Turbo output has dropped to under 1000 lumens, and stays there for much of the remainder of the runtime.
High looks approximately like Turbo, but with better regulation, and slightly lower output at just under 900 lumens.
In both cases, the light never actually shut off fully, but did have a very low output. In both cases, this was around 3V.
The MH25GTS also has on-board charging, through a micro-USB port in the tailcap. Like the MH12GTS, this is a waterproof port.
Charging proceeds at around 0.65A and takes much too long. The charge graphs look great, because charging is extremely consistent. Also the cell is testing well over the 3500mAh claim, which again, is good (“well over” because I’ve logged Ah at 5V).
One huge complaint about this light is that the plug for the micro-USB port doesn’t stay in very well at all.
Nitecore also includes a nice charge cable (USB to micro-USB).
User Interface and Operation
There are two switches on the MH25GTS. The first is a mechanical tail forward clicky switch. It’s a nice rubber button, and fairly resistive.
The other switch is a side, indicating, e-switch.
It’s not proud at all, but the light is built so that there’s plenty of reveal for good access to the switch. It’s an indicating switch, and when the switch indicates, it’s very noticeable, and even in it’s illumination.
The UI is much like many of Nitecore’s other dual-switch lights but I think adds some features that are interesting.
Here’s a UI table!
|Off||Click Tail Switch (TS)||On (Mode Memory including Strobe)|
|On||Click Mode Switch (MS)||Mode advance (L>H direction)|
|Off||Hold MS, Click TS||Ultralow|
|Off||Depress TS||Momentary Mode Memory|
|On||Depress TS||Momentary Turbo|
|On||Double click MS||Strobe|
|Strobe||Long click MS||Strobe advance (Beacon>SOS>Strobe)|
|Strobe||Click MS||Return to regular modes (mode memory)|
|Off||Press MS||Power Indication on indicating switch|
Power indication is as follows (and is typical for Nitecore):
1. 3 Flashes represent battery level above 50%
2. 2 Flashes represent battery level below 50%
3. 1 Flash represents battery level below 10%
|Mode||Mode Claimed Output (lm)||Claimed Runtime||Measured Lumens||Tailcap Amps|
Due to the inner sleeve/charging function of this light, I wasn’t able to test the amps. I tried a bunch of ways, and I could just never get it to work with my setup.

Random Comparisons and Competitive Options….
Here’s a relevantly filtered page on parametrek.com. There are some other good lights in this category. The Nitecore is probably good for tactical use, with the thick dual springs, and the versatile UI. I have and still like the Skilhunt S3 Pro, which is comparable. The Nitecore is a good choice as a complete package light.
What I like
- Complete kit light
- Meets throw claim
- On-board charging is very consistent and stable
- Dual switch UI is fairly good
- Indicating side switch is reasonably well used
What I don’t like
- Falls short of output claim
- On-board charging is very slow
- Charge port cover doesn’t want to stay put
I have a couple of cell reviews upcoming, and then lights! More lights! Also I now have a QC 3.0 charge port, so I can test some chargers that are in, too.
Also, welcome to the new site! I finally migrated from zeroair.wordpress.com, and this will be my home now. I’ll probably serve some ads, because hosting isn’t cheap (ie it’s not free) but they’ll be run by Google Adsense, so hopefully will not be offensive like some other that turned up through wordpress.com. If you have suggestions about my site, I’d love to hear. I want to make it better! At the least, the layout should be a little better, with bigger images, and easier clicking to the biggest images.
