Flashlight Enthusiast
Klarus has released the XTQ1, features a quiet tailcap switch interface and the XM-L2 U2 emitter. The light runs on 1x18650 Li-ion or 2xCR123A battery source.
.
.
Like the RS11, the light comes in a store-shelf display packaging. Included in the packaging was the light with removable clip (attached), lanyard, spare o-rings, grip ring (attached), key-chain, manual.

The hard (type III) anodizing is a matt dark brownish gray and consistent throughout with no chips or blemishes to be found on my review sample. Lettering is not very bright white, but legible against the background.
.
.
You can take the light apart without any tools and get three parts.
.
.
The XTQ1 has a stainless steel crenellated bezel ring are removable, allowing light to shine through when left placed head down. Like the RS11, the bezel ring is not directly touch the o-ring & lens in the head. There is an inner ring similar to bracket between the bezel ring and lens. This structure seems more shock-resistance.
There is a raised contact spring in the head of the light, so flat-top 18650 batteries should work fine in the light. The light has reverse polarity protection to protect from incorrect battery installation (i.e., the electronics of the XTQ1 has in-built reverse polarity protection).
.
.
The light uses toughened ultra-clear lens. The purple hue is reflected on it. The aluminum reflector has a light orange peel pattern. Surface finish on the reflector is nice from visual inspection, and well-centered LED sits at the bottom of the reflector cup.
.
.
The battery tube (i.e., body) has no knurling. But with all the ridge detail and extra elements around the head and body, overall grip is good. The stainless steel clip-on pocket clip seems to hold on fairly well. It is head-facing, and not reversible. The bundled grip ring is a metal. It can spin even when the tailcap is fully tightened, but it's not inconvenient using the light.
The wall thickness of the body is about 1.9mm, and the light seems reasonably solid.
.
.
The screw threads are trapezoidal-cut of good quality. Both male and female threads in the head and tail part are well machined, with being anodized which allows the light to be locked-out when the head or tailcap is slightly loosened. Threads on the both ends of the body mate well with no issues of cross-threading or grinding.
.
.
At the tail base, you can see a slightly sunken surface that is very flat. The distinctive aspect of the light is a metal flat switch with no audible click when pressing it. This switch gives you a large contact area and allows the light tailstand perfectly. The switching travel is shorter than average, with average resistance. The tail assembly can be disassembled using snap-ring pliers or a long-nose pliers with ease. You will see the spring contact with a electronic circuit. It means there needs to be a standby current when the tailcap is fully connected.
There is a brief pre-flash when making initial contact of the tailcap with the battery, and a second pre-flash when fully tightened. There is also a brief pre-flash when the tailcap is fully loosened. There is no pre-flash when activating the light in any mode.
.
.
User Interface
You can temporarily press for momentary. Press and hold it for more than 1.5 secs to stay locked-on. Turn the light on by a long press for more than 1 sec, and turn the light off in the same way.
Click the switch to cycle through High -> Med. -> Low output and release the switch to select the output.
A double quick press (or double quick click) will activate Strobe, whatever mode the light is in (even Off). Click the switch again to return to the original state.
There is no memory for all outputs and Strobe. The light always comes on in High.
.
.
Standby Current Drain
Because the switch is electronic, there is a standby current when the light is fully connected with batteries installed inside the light. I measured this current as 3.9uA. Considering one 2600mAh capacity battery, that would give you around 76 years before one fully charged battery would be completely drained. This is quite negligible, not a concern, but you can break this current completely by slightly loosening the tailcap a little for lock-out, thanks to the anodized threads, when not in use.

Measured Dimensions & Weight
.
.
It is very good size to hold. Overall grip is good. Overall build quality is very high.
.
.
PWM
There is a visible PWM flicker on Low and Med. mode when shaking the light. But Hi호 has no visible evidence of flicker. I notice there is no buzzing sound on Low and High, but some buzzing sound on Med. only. In my view, this PWM & buzzing sound are not too bad, but acceptable to use the light in real life.
.
.
Runtime
XTQ1 steps down on High after about 5 mins runtime on all battery sources. Runtime on 2xCR123A is not shown above, because I erased the related data by mistake. I'm sorry about that. The above runtime labelled as "Accumulated High" is an accumulated runtime for High output (i.e., the light steps down on High to Med. after about 5 minutes, and can go back to High by clicking the tail switch or turning the light off-on).
I remember initial output increased on 2xCR123A relative to 1x18650.
.
.
Overall output-runtime efficiency seems fine.

Beamshot
1. White door beamshot (about 50cm from the white door) on max. output on 1x18650 VicLite protected cell
- ISO125, F/8.0, 1/25sec, Auto white balance
.

- ISO125, F/8.0, 1/100sec, Auto white balance
.
.
- ISO125, F/8.0, 1/800sec, Auto white balance
.
.
- ISO125, F/8.0, 1/2000sec, Auto white balance
The light has a middle sized bright hot spot. The hotspot is well focused. A soft corona surrounding the hotspot is slightly yellow. There is shadow cut-out on the periphery of the spillbeam, due to the deep crenellated bezel ring. The beam tint is typical cool white on my sample.
.
.
2. Indoor beamshot (about 7m from the target) on max. output on 1x18650 VicLite protected cell
- ISO125, F/2.8, 1/10sec, Auto white balance
.
.
.
.
3. 55m Outdoor Beamshot on max. output on 1x18650 VicLite protected cell
- ISO125, F/2.8, 1sec, Auto white balance

.
.
4. 85m Outdoor Beamshot on max. output on 1x18650 VicLite protected cell
- ISO125, F/2.8, 1sec, Auto white balance
.
.
Beam pattern is good, Throw is reasonable for the class, given the size of the head and reflector.
