Acebeam is offering a 4000K version of the T36 dual switch tactical flashlight with a CREE XHP35 HI! This incredible light just got better.
Official Specs and Features
Here’s a link to the Acebeam T36 4000K tactical flashlight product page.
There are a couple of emitter options: 6500K, and 4000K (seen here). There are no body options.
The Acebeam T36 4000K tactical flashlight is selling for $109 at KillzoneFlashlights.com.
This is a fantastic light – 4000K XHP35 HI is becoming one of my favorites. The whole package from Acebeam here is great, too. All in all, a capable, pleasant package.

Package and Manual
Build Quality and Disassembly
One of the main things you might notice is that silver strike bezel. It’s easily removable, and reversible, and really a neat little attachment! The second thing you might notice is that the tailcap is quite thick! Has to do with all the electronics allowing charging, but yeah, in use it’s noticeably thicker.
Below is a “top down” view.
The head has nice deep cooling fins.
That tactical ring is very easy to remove. The threads are even very short.
Unfortunately the bezel can’t be removed seamlessly – it’ll come off completely, but you’re left with some fairly fine threads exposed. The lens or reflector will not fall out, however.
Here’s the bezel reversed. It doesn’t screw down all that far, but in this setup makes for an interesting display when placed on it’s head, and on.
Both the head and tail have thick, beefy springs, which you’d expect on a tactical flashlight.
There’s a bunch of stuff going on in the electronics, since this is a charging light. Both the tail and head have big beefy springs, but also little finger connectors, which allow charging.
Size and Comps
Size: 145mm (Length) x 30mm (Head Dia.) x 25.4mm (Body Dia.)
Weight: 113g without battery
If a light will headstand, I’ll show it here (usually the third photo). If a light will tailstand, I’ll show that here, too (usually the fourth photo).
Here’s the test light with the venerable Convoy S2+. Mine’s a custom “baked” edition Nichia 219b triple. A very nice 18650 light.
And here’s the light beside my custom engraved TorchLAB BOSS 35, an 18350 light. I reviewed the aluminum version of that light in both 35 and 70 format.
Retention and Carry
Included and attached from the factory is a friction fit pocket (or belt) clip. It’s very snug.
And finally, the lanyard attachment point, which is on the tactical ring. The tactical rings does come off, and is not threaded.
Included is a nylon pouch, which this tube light will easily fit into bezel up or down.
Power and Runtime
Primarily the T36 will be powered by the included 5100mAh 21700 liion cell. Also included to allow some versatility is an adapter to allow 18650 cells.
The springs on both ends inside should mean that any cell type will work fine.
The cell is installed the normal way – positive terminal toward the head.
Here’s a runtime on Turbo. The stepdown is fairly quick, and possibly temperature based. The light steps down dramatically, to around 700 lumens.
I tested three other modes (all but the lowest mode!). Each displays a main emitter flash when cell voltage is low. Output is very stable on all modes.
At the end of the runtimes, the light’s main emitter flickers on and off, and the light does shut off with a cell voltage of around 2.9. That’s fairly good behavior, and certainly good for the cell. (Less good if you’re in a tactical situation and must have light, though.)
The T36 has on-board charging, via a nicely covered USB-C port. A cable is included, seen below.
The charge port is on the head, and covered by a press-in rubber boot.
The charge port is opposite the e-switch in the head. Just near the e-switch is a status indicator, that seems to indicate nothing more than charge status. If the light is charging, the indicator is red. If charge is finished and the light is connected to power, the indicator is green. Unfortunately this seems to be all the indicator does!!
Modes and Currents
These output claims are almost certainly for the 6500K version. Acebeam has a (bad?) habit of not speccing the neutral versions of their lights.
|Mode||Mode Claimed Output (lm)||Claimed Runtime||Measured Lumens||Tailcap Amps|
Pulse Width Modulation
There is no pwm to be seen here.
For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor. And here’s the worst PWM light I have ever owned. Also one of the very first lights I ordered directly from China!
User Interface and Operation
There are two switches on the T36.
First is a mechanical switch on the tail cap, just like on the L16.
There’s a metal switch like is on the EC65, in the center of the head. It’s a very flush button, and very positively clicky (but not loud). I like this switch a lot.
Here’s a UI table!
|Off||Click Side Switch (SS)||On (Mode Memory)|
|Any||Click Tail Switch (TS) (Even during Lockout)||Turbo (Steady) (and precludes Side Switch use)|
|Any||Tap TS (Even during Lockout)||Momentary Turbo|
|On||Double Click SS||Turbo|
|On (Non strobe)||Hold SS||Mode advance (LMH)|
|Any||Triple Click SS||Strobe|
|Off||Hold SS >3s||Lockout (Signified by two flashes of Moonlight)|
|Lockout||Hold SS <3s||Unlock to Moonlight (one flash of Moonlight, then steady Moonlight)|
LED and Beam
Acebeam has a Cree XHP35 HI in the T36. In this case, it’s a 4000K cct emitter, and that’s very much what I’d recommend you buying. The reflector is small and fairly shallow.
These beamshots are always with the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
Test light is on the left!
I compare everything to the KillzoneFlashlights.com 219b BLF-348, because it’s inexpensive and has the best tint!
What I like
- Great full package setup
- Build quality is great
- Good user interface
- The 4000K emitter is wonderful
- USB-C charging! (with a very snug charge cover)
What I don’t like
- Indicator near e-switch is definitely underutilized
- This light was provided by KillzoneFlashlights.com for review. I was not paid to write this review.
