Introduction#

The Amutorch XT60 with a Luminus SFT90X is a beast! This thing draws some serious current and the beam reaches about 1.3km.

Here is a video demonstration:

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 XT60 SFT90X came in a plain cardboard box with an Amutorch sticker on top.

The following was included in the box:

Amutorch XT60 SFT90X.
Spare o-ring.
Tactical ring.
Lanyard.

Torch in use#

The Amutorch XT60 feels a bit short given how big the reflector is.

The tactical ring help with an overhand grip. It is a bit top heavy.

There are lanyard holes cut into the side of the tailcap to allow the torch to tail stand without a lanyard getting in the way.

Build quality#

The Amutorch XT60 has a matte black anodised finish.

I like the tactical look and feel.

There is plenty of grip.

There is a beefy spring in the tailcap to help with the current (I measured 16A on Turbo from a bench power supply!).

The threads are anodised and they turn smoothly.

The build quality is pretty good.

LED, bezel, lens, reflector and beam#

This Amutorch XT60 has a Luminus SFT90X emitter surrounded by a square gasket and a smooth reflector.

A steel bezel is screwed down to hold the glass lens against the top of the reflector.

CCT, CRI, and duv#

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

The CCT is around 6000K, the CRI is around 66 and the Delta u, v is positive (green).

The beam produced has an intense hot spot with a flower pattern. Perhaps the reflector is a bit small given the size of the emitter. There is a small ring in the beam from the inner part of where the reflector connects to the gasket and there are some rings around the edge of the spill from the bezel.

Mode	CCT (K)	CRI (Ra)	x	y	Duv
Low	5819	65.3	0.3250	0.3480	0.0069
High	5894	65.7	0.3235	0.3454	0.0063
Medium	6065	66.7	0.3202	0.3392	0.0047
Turbo	6184	67.6	0.3183	0.3339	0.0029

User interface#

The Amutorch XT60 SFT90X has an electronic side switch.

The torch has smooth ramping and stepped ramping.

There are three modes in the main group: Low, Medium and High. And there are shortcuts to Turbo and Strobe.

Group	State	Action	Result
	Off	Press and hold	Moonlight (Smooth Ramping)
Smooth	On	Press and hold	Ramp up or down
Smooth	On	Click	Off
	Off	Click	On (mode memory)
Stepped	On	Click	Cycle (Low, Medium, High)
Stepped	On	Press and hold	Off
	Any	Two clicks	Turbo
	Any	Three clicks	Strobe
	Any	Four clicks	Lock
	Locked	Four clicks	Unlock

Mode memory#

There is mode memory.

The torch will memorise the last used mode (Low, Medium or High).

Strobe#

Strobe has a constant frequency.

I measured Strobe with a Zoyi ZT-701 oscilloscope.

Low voltage protection#

There is low voltage protection. The light turns off around 2.9V.

I tested low voltage protection by connecting the driver of the torch to a bench power supply and then by lowering the voltage from 4.2V to 0V.

Pulse Width Modulation#

I did not notice any visible PWM (flickering).

I measured the PWM of the light with a Zoyi ZT-701 oscilloscope.

Low, Medium, High, Turbo

What I like about the UI#

The light flashes at the top and at the bottom of the ramp.
Shortcut to Moonlight from off.
Shortcut to Turbo.
Shortcut to Strobe.

What could be improved#

A lower Moonlight mode would be nice when using smooth ramping. It is currently about 10 lumens.

Batteries and charging#

Battery#

The torch takes a 21700 3.7V Li-ion cell.

I tried the following cells:

Cell	Top	Compatible?	Comment
EVE 50PL 21700 3.6V Li-ion 5000mAh	Button	Yes
Molicel P42A 21700 3.7V Li-ion 4200mAh	Flat	Yes
Molicel P45B 21700 3.7V Li-ion 4500mAh	Button	Yes
NEXTORCH 21700 5000mAh 3.6V Li-ion USB-C	Button	No	Too long.

Charging#

There is no built-in charging.

Performance#

There are a few specifications mentioned on the product page but there is no user manual.

	Low	Medium	High	Turbo	Strobe
Output (lumens)				5,300
Runtime
Beam Distance (metres)				1,306
Beam Intensity (cd)				426,862

I tested the light using a Molicel P45B 21700 3.7V Li-ion 4500mAh cell.

Lumen measurements#

I used a bench power supply to measure the current at turn on.

Mode	Amps at start	Specs	Lumens @turn on	Lumens @30 sec	Lumens @10 min
Moonlight	22 mA		13	11	13
Low	0.48 A		322	318	318
Medium	1.00 A		627	619	617
High	3.30 A		1,571	1,551	1,529
Turbo from on	18.05 A	5,300	5,334	4,694	1,505
Turbo from off	18.05 A		5,455	4,689	0

The lowest output when using smooth ramping is what I call “Moonlight” and it is about 10 lumens.

Stepped ramping has a much brighter Low mode at 300+ lumens.

Standby drain#

31 µA

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.

The room temperature was approximately 15 C.

Runtime#

Here is a summary of the runtime results:

Mode	Runtime	Turn off	Final voltage
Turbo from off	1min 52s	1min 52s	4.06
Turbo from on	1h 8min 7s	1h 8min 7s	2.96
High	1h 16min 35s	1h 16min 35s	3.12
Medium	3h 48min 28s	3h 48min 28s	3.04
Low	7h 39min 51s	7h 39min 51s	3.02
Moonlight	10min+	10min+

“Runtime” is the time until the output reduces to 10% of the output at 30 seconds (as per the ANSI/PLATO FL1 2019 Standard).

“Turn off” is the time until my DIY lumen tube no longer detects more than one lumen.

“+” indicates that the light remained on after recording had stopped.

Turbo lasts almost 2 minutes when activated from off.

The output is well regulated and the runtimes are pretty good.

Throw#

I took lux measurements with a UNI-T UT383BT at 30 seconds. Turbo was measured at five metres.

Mode	Specs (cd)	Specs (m)	Candela measured (cd)	Distance (m)
Turbo	426,862	1,306	393,000	1,253

Thermal Images#

I used a Thermal Master P3 thermal camera to take a video of the torch while using Turbo. Get 10% off the Thermal Master P3 with code Mcmahon10

Room temperature: 12 C

Time (mm:ss)	Max Temperature
00:00	15.6 C
01:00	36.0 C
02:11	52.6 C

The temperature peaked at 52.6 C just after 2 minutes and the light turned off.

Beamshots#

I went to a local park and aimed the torch at a tree 70 metres away.

Beamshots were taken using a Sony RX100M2 using 3.2", f3.2, ISO 100, 5000K WB.
