Introduction#

Are we playing chess today?

The ReyLight Rook Ti Stonewashed is a powerful little floodlight! It has three FFL351A 4500K emitters behind a TIR optic to produce a beautiful wall of light. It is powered by an 18350 battery.

The head and the body can be swapped like Lego with the ReyLight Dawn Max Ti Stonewashed.

ReyLight kindly sent this torch for review. I have not been paid for this review nor have I held back my opinions of this torch.

Packaging#

The ReyLight Rook Ti Stonewashed comes in a simple transparent box with a white ReyLight-branded cardboard sheath.

Torch in use#

The ReyLight Rook Ti Stonewashed feels tiny to hold!

ReyLight Rook Ti Stonewashed in-use-3 ReyLight Rook Ti Stonewashed in-use-2

The pocket clip fits tightly over the loop of my backpack strap for EDC.

The torch is controlled by a reverse-clicky tail switch.

ReyLight Rook Ti Stonewashed in-use-1

This little pocket floodlight can tailstand, headstand, lay on its side, or be used for a quick game of chess.

Build quality#

The ReyLight Rook Ti Stonewashed is made of titanium and it has a stonewashed finish. It is available in multiple finishes (raw titanium, beadblasted titanium, stonewashed titanium, various anodised titaniums).

I accidentally scratched the tube with the pocket clip by unscrewing the tailcap instead of the head whilte removing the battery.

ReyLight Rook Ti Stonewashed side

Overall, the build quality is pretty good.

LED, bezel, lens and reflector#

The bezel of the titanium stonewashed head has an o-ring pressing down against a glass lens, a TIR optic, a glow-in-the-dark gasket and the MCPCB with three FFL351A 4500K emitters.

The pill can be unscrewed to access the TIR optic but I do not recommend trying to this at home! You could damage the emitters by twisting the TIR optic against them (like i did).

Here is a partial teardown:

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 one metre away from an Opple Light Master Pro III (G3).

The CCT is around 4500K, the CRI is aroun 98 and the Delta u, v is positive (rosy).

The beam produced is floody and it has a beautiful tint.

State Action Result
Off Click On
On Click Off
On Half click (tap) Cycle (Moonlight, 2%, 20%, 100%)
On Double half click (tap) 100%

Here are some of the things that can be configured:

  • select one of four mode groups;
  • toggle mode memory on or off;
  • toggle moonlight mode on or off;
  • change the cycle order (Low to High, or High to Low).

Here is a Programming Guide from Rey’s website:

To Enter Configuration Mode:  

- From ON, half-click/tap the tail switch 8+ times until it starts to flash.  

(When the configuration mode is entered, the light will start to blink once, then a quick flash, blink twice, then a quick flash, blink three times, then a quick flash, blink four times, then a quick flash, blink five times, then a quick flash. This sequence continues twice if a selection is not chosen)  

* The number of blinks indicates the configuration option number to be changed.  
* Half-click/tap the tail switch during any quick flashes following the blinks to select the configuration option.  

- Here are the configuration options:  

1. Mode group selection  

(After entering this menu, you can see it blink 4 times. The number of blinks indicates the number of mode groups)  

The 1st blink -------- Group1:  (Moonlight)-2%-20%-100%  
The 2nd blink -------- Group2:  (Moonlight)-10%-40%-100%  
The 3rd blink -------- Group3:  (Moonlight)-2%-10%-50%  
The 4th blink -------- Group4:  (Moonlight)-50%-100%-Strobe-SOS  

* Half-click/tap the tail switch during any blinks to select the mode group.  
* After selecting the mode group, you can half-click/tap to select the brightness mode.  

2. Memory mode on-off toggle (default off)  

To turn memory mode on, half-click/tap the tail switch during the quick flash after the second blink.  

* To turn off the memory mode, reenter the configuration mode and repeat the instruction above.  

3. Moonlight mode off-on toggle (default on)  

To turn the moonlight off, half-click/tap the tail switch during the quick flash after the third blink.  

* Repeat to turn the moonlight on.  

4. Mode order toggle (default LMH)  

To change the mode order from Low Medium High to High Medium Low, half-click/tap the tail switch during the quick flash after the fourth blink.  

* Repeat to reverse the order.  

For example, the default mode order of group 1 is (Moonlight)-2%-20%-100%, if you change the mode group to HML, the mode ORDER of group 1 will be (Moonlight)-100%-20%-2%  

5. Factory reset  

Half-click/tap the tail switch during the quick flash after the fifth blink to reset all options to their original states.  

Strobe#

Strobe has an alternating frequency.

Strobe, SOS

ReyLight Rook Ti Stonewashed strobe ReyLight Rook Ti Stonewashed sos

I measured Strobe and SOS with a Zoyi ZT-706S oscilloscope using High Speed mode.

Low voltage protection#

There is low voltage protection. The light turns off around 2.7V.

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-706S oscilloscope.

What I like about the UI#

  • Simple to use.

What could be improved#

  • A printed user manual with a programming guide might be helpful.

Batteries and charging#

Battery#

The torch came with a protected button top 18350 3.7V Li-ion cell with USB-C charging. The cell arrived with a voltage of 3.78V.

The capacity is not stated on the battery but I measured a capacity of 1,163 mAh by discharging the battery at a rate of 1A with an Atorch DL24P electronic load.

ReyLight Rook Ti Stonewashed battery-1 ReyLight Rook Ti Stonewashed battery-2

The cell was isolated with a piece of card to prevent accidentally turning the torch on.

ReyLight Rook Ti Stonewashed closeup-isolating-strip

I tried the following cells:

Cell Top Compatible?
ReyLight 18350 3.7V Li-ion 1200mAh? Button Yes
KeepPower IMR18350 3.7V Li-ion 1200mAh Button Yes
Vapcell F14 18350 3.7V Li-ion 1400mAh (green) Recessed Yes
Vapcell M11 V2 18350 3.7V Li-ion 1100mAh (yellow) Flat Yes

Flat top cells work but they are a bit short. Shaking the torch could cause the battery to disconnect.

Charging#

The torch does not have built-in USB-C charging. The battery has USB-C charging.

Power supply: PinePower Desktop USB-C
USB Meter: ChargerLAB Power-Z KM003C Amazon Australia
Room temperature: 15 C

ReyLight Rook Ti Stonewashed charging profile

It took 1 hour 53 minutes to charge the battery from 2.90V to 4.20V at a rate of 5V/0.7A.

The charging status indicator in the battery is red while charging and it becomes green when charging is complete.

Power supply compatibility#

I tried the following power supplies:

Power supply USB Type Protocol Does it charge?
PinePower Desktop USB-C PD Yes
PinePower Desktop USB-A QC Yes
PinePower Desktop USB-A Yes

USB-C to USB-C charging works.

Performance#

There was no user manual with specifications included.

I used the included 18350 USB-C cell for the following tests.

Lumen measurements#

Mode Amps at start Lumens @turn on Lumens @30 sec Lumens @10 min
2% 0.15 A 74 72 68
10% 0.28 A 234 223 207
20% 0.63 A 464 434 373
50% 2.19 A 1,201 1,052 304
100% 4.00 A 1,928 1,565 298

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

Runtime graphs#

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

The room temperature was approximately 15 C.

Runtime#

Here is a summary of the runtime results:

Mode User manual Runtime Turn off Final voltage
100% 1h 13min 13s 1h 22min 10s 2.89
50% 1h 19min 0s 1h 23min 35s 2.90
20% 1h 7min 37s 7h 26min 23s 2.86
10% 2h 24min 53s 2h 24min 54s 2.89
2% 8h 15min 51s 11h 44min 15s 2.69

“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 1 lumen.

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

The runtimes are pretty good. It would be nice if the lumen output was constant.

Throw#

I took lux measurements with a UNI-T UT383BT at 30 seconds. 100% was measured at five metres.

Mode Candela measured (cd) Distance (m)
100% 7,150 169

Beamshots#

I went to a local park and aimed the torch at a tree 70 metres away while using 100%.

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

Thermal Images#

I used a Thermal Master P3 to take thermal images of the torch while using 100% mode. Get 10% off the Thermal Master P3 with code Mcmahon10

Room temperature: 20 C

Time (mm:ss) Max Temperature
00:00 28.1 C
01:00 81.9 C
02:00 94.9 C
03:00 86.7 C
04:00 83.7 C
05:00 82.3 C

The surface temperature near the head peaked at around 96 C within the first two minutes and then it began to cool down. This is a powerful little torch! It gets too hot to touch near the head but I can hold it comfortably by the tail end.

The temperature measurement could be slightly off. I tried to figure out the emissivity of the stonewashed titanium finish as follows:

  • Position the torch 0.2 metres away from the Thermal Master P3 and set the emissivity to 0.95.
  • Put black electrical tape on the head with an approximate emissivity of 0.95.
  • Turn the torch on in 100% mode for 2 minutes.
  • Measure the temperature of the tape (83.4 C).
  • Spin the torch around and measure the temperature of the stonewashed titanium within 5 seconds (64.7 C).

I then fully charged the battery, removed the tape, let the torch cool down, and took six more measurements with the Thermal Master P3 configured with an emissivity of around 0.6 to 0.7 (0.62).

Here are those thermal images:

Conclusion#

If you like stonewashed titanium and 18350-sized torches that pack a punch, then the ReyLight Rook Ti Stonewashed should join your EDC collection!

The beam looks beautiful and it is powerful on Turbo mode (100%).

I managed to scratch the stonewashed finish pretty badly by unscrewing the tailcap by mistake instead of the head. The stiff pocket clip scratched the surface.

I regret unscrewing the pill to take a teardown photo. I managed to damage one of the LEDs by twisting the TIR optic against it. What a rookie mistake!

This torch is a nice addition to any titanium EDC collection but you may want to take care of it. I will see if I have some spare FFL351A emitters laying around and figure out how to fix the surface finish (fixing stuff is fun too).

I wonder if Rey will make an entire chess set…

Pros:#

  • Good build quality.
  • Good runtimes.
  • High CRI.
  • Beautiful beam.
  • Simple user interface.

Cons:#

  • It gets very hot on 100% mode.
