Introduction⌗

The Amutorch XT35 is essentially a LED version of the tactical Amutorch BT35 LEP. It shares a similar host but has a Luminus SFT40 emitter instead of a LEP module.

The XT35 comes in two versions: balanced or high-output. Both versions have Low, Medium and High modes but the intensity for Medium and High are lower for the balanced version. I have the high-output version.

This torch was sent by Nealsgadgets for review. I have not been paid for this review nor have I held back my opinions of this torch.

Packaging⌗

The XT35 came in a plain cardboard box with an Amutorch sticker on top. The torch was well protected inside bubbble wrap and foam.

The following was included in the box:

• Amutorch XT35
• Tactical ring
• Cigar grip
• Two plastic tailcap rings
• Two spare o-rings
• Holster
• Instructions in Chinese

Torch in use⌗

The Amutorch XT35 fits perfectly in the palm of my hand.

The forward clicky button gives a satisfying click and it is easy to use.

It is slightly slippery due to having a smooth tube.

The cigar grip can help prevent the torch from falling out of your hand and it also helps stop it from rolling around on a flat surface.

The tactical ring can be attached between the tube and tailcap. It has a deep carry pocket clip one one side and a ring on the other. The ring allows you to operate the torch and a firearm without it necessarily getting in the way.

The torch can tailstand when using the larger tailcap ring but I prefer to use the shorter ring so that it is easier to click the button.

Build quality⌗

The Amutorch XT35 is constructed of aluminium. The body has a matte black anodised finish on both the outside and the inside. The torch feels smooth and there are no sharp edges.

The rubber switch boot feels firm. The tailcap has a thread where a small or large plastic ring can be screwed on. The small ring helps prevent accidental activation while the larger ring allows the torch to tailstand.

Thin square cut threads on the tube came lightly lubricated and they allow the tailcap to turn smoothly.

There is a brass retaining ring with two notches in the tailcap holding down a PCB for the tail switch.

I used two strap wrenches to snap the glue and unscrew the head from the tube. The driver appears to be glued down.

The XT35 fits the included holster and there is a sufficient gap to easily grab the head of the torch and take it out. I prefer to use the tactical ring with a pocket clip instead of the holster.

LED, bezel, lens, reflector and beam⌗

The Amutorch XT35 comes with a cool white Luminus SFT40 emitter and a smooth reflector. This combination is excellent for producing a throwy beam.

The bezel is screwed onto the head without glue and there are two o-rings to help prevent water from getting in.

The bezel can be unscrewed, and the lens taken out, to reveal the smooth reflector.

The reflector simply lifts out. It has a white gasket to help keep the reflector centered around the emitter.

I have taken Correlated Colour Temperature (CCT) and Colour Rendering Index (CRI, RA of R1-R8) measurements with the torch positioned a metre away from an Opple Light Master Pro III (G3).

The CCT ranges from 6000K on Low to 6871K on High. CRI is around 69.

The Delta u, v is slightly positive (green) on Low and Medium. It is almost neutral (pure white) on High.

The beam has an intense white hot spot, a white corona, and a wide spill with an outer ring.

Mode	CCT (K)	CRI (Ra)	x	y	Duv
Low	6076	67.5	0.3197	0.3431	0.0069
Medium	6442	69.1	0.3137	0.3304	0.0034
High	6871	70.6	0.3080	0.3187	0.0003

User interface⌗

State	Action	Result
Off	Half press	Momentary on (mode memory)
Off	Double half press	Cycle (Low, Medium, High)

Low voltage protection⌗

There is low voltage protection. The torch flashed at 3V and turned off at 2.96V with a current of 4.37 mA.

PWM⌗

I did not notice any visible PWM (flickering).

What I like about the UI⌗

• Simple to use.

What could be improved⌗

• This is a tactical torch so it would be nice to have a Strobe mode.
• A shortcut to High from off could be added.

Batteries and charging⌗

Battery⌗

The Amutorch XT35 has two small springs at each end for one unprotected flat top 18650 3.7V Li-ion cell.

I successfully used an unprotected flat top Sanyo NCR81650GA cell.

I tried to use a protected button top 18650 cell without built-in charging but it was too long.

Charging⌗

There is no built-in charging.

Performance⌗

Specifications:

ANSI/NEMA FL1	balanced version	high-output version
Light Output (lm)	1170/350/50	1800-750/750/50
Runtime	1h18min/4h40min/41h	6min+1h48min/2h15min/41h
Beam Intensity (cd)	71,000	110,000
Beam Distance (m)	533	666

I have used a Sanyo NCR81650GA 3500mAh cell for testing.

Lumen measurements⌗

I used a UNI-T UT210E clamp meter to measure the current at turn on.

Mode	Amps at start	Specs	Lumens @turn on	Lumens @30 sec	Lumens @10 min
Low	0.08 A	50	51	51	53
Medium	1.43 A	750	719	695	659
High	5.16 A	1,800	1,648	1,532	624

Standby drain⌗

There is no standby drain. This torch has a mechanical tail switch.

Runtime graphs⌗

I used my own DIY lumen tube with a TSL2591 sensor and forked bmengineer’s project RuTiTe to record runtimes.

Note: Lumen measurements may be off by 10% with my DIY lumen tube.

High started at 1,648 lumens, dropped to 620 lumens after minutes, and maintained 620 lumens for slightly over 2 hours. The initial burst falls short, 3 minutes instead of 6 minutes, but the overall runtime is better than Amutorch’s estimate.

Medium started at 719 lumens, dropped to 620 lumens after an hour, and maintained 620 lumens for almost 2 hours 10 minutes. This lines up with Amutorch’s estimate of 2 hours 15 minutes.

Low started at 51 lumens and maintained that output for 24 hours. I stopped recording at 24 hours.

Overall, the lumen measurements were slightly lower than expected for High and Medium but the runtimes were as expected.

Runtimes for this high-output version of the Amutorch XT35 seem better than the Brinyte HL18 Noctua but they fall short when compared to the Olight Warrior Mini 2. The balanced version of the XT35 has longer runtimes.

Throw⌗

I took lux measurements with a UNI-T UT383BT at 30 seconds at a distance of five metres for each mode.

Mode	Specs (cd)	Specs (m)	Candela measured (cd)	Distance (m)
Low			2,800	105
Medium			39,700	398
High	110,000	666	89,175	597

Beamshots⌗

I went to a local park and aimed the Amutorch XT35 at a tree 70 metres away while using High.

Beamshots were taken using a Sony RX100M2 using 3.2", f3.2, ISO 800, 5000K WB.

Conclusion⌗

I like how Amutorch have taken the BT35 LEP and produced an LED version. The tactical ring seemed a bit inappropriate with the LEP but it is perfect for a torch with a Luminus SFT40 LED. I find it so much easier to identify things using the XT35 compared to the BT35 due to the wide spill and throwy beam.

Light output is well regulated. If you want a longer runtime then you would be better off getting the balanced version of the XT35 instead of this high-output version. High and Medium finished after about 2 hours. The balanced version might reach over 4 hours on Medium.

This torch is clearly trying to be for tactical purposes with the tactical ring but it has omitted Strobe and direct access to High from off. The XT35 may be more useful as a pocket sized spotlight for hunting.

Pros:⌗

• Good regulation
• Good build quality
• Forward clicky tail switch
• Fits my hand perfectly
• Tactical ring
• Holster

Cons:⌗

• Low CRI
