Package deal and Guide
There isn’t any handbook.
Construct High quality and Disassembly
The construct high quality of the ReyLight Penlight MkII Aluminum is sweet. It has a fairly typical construct high quality of different ReyLights, and the “uncooked aluminum” is a good end, too.
I don’t understand how the sunshine is made (or “completed”), however it does appear to me in these photographs and in individual that the pinnacle is ever so barely completely different than the physique.
The pinnacle has a tiny brass button. I imagine the driving force is screwed in.
Down contained in the cell tube is a spring on the swap.
Measurement and Comps
Formally: 134.2mm size (together with the swap button), Diameter: 15mm
Right here’s the sunshine in hand:
Right here’s the check mild with the venerable Convoy S2+. The model under is a customized laser-engraved Convoy S2+ host by GadgetConnections.com. I did a full put up on an engraved orange host proper right here! Or go straight to GadgetConnections.com to purchase your Convoy S2+ now!
Additionally within the photograph above, my Commonplace Reference Materials (SRM) flashlight is the Hanko Machine Works Trident, an 18350 mild. Whereas I’ve not reviewed or examined the Gunner Grip model seen right here, I’ve examined a Hanko Machine Works Trident Complete Tesseract in brass. I really like the Trident, and it’s a hanging distinction to the cheap Convoy S2+, one other nice SRM.
Retention and Carry
The ReyLight Penlight MkII Aluminum flashlight in titanium ships with a two-screw clip put in.
This clip is an improve or distinction from different Reylight Penlights. This two-screw model of the pocket clip carries a bit shallower than the bent collar clip.
Additionally, notably (most likely moreso on this uncooked aluminum mild), the clip will rub the end as you unscrew the physique. You’ll be able to keep away from that by all the time unscrewing the pinnacle for cell swaps. Or you can throw a protecting piece in there. Both approach, these scratches are avoidable.
Energy and Runtime
The ReyLight Penlight MkII Aluminum flashlight in titanium can run two 1.5V cells (double AAA), and in addition the included 4.2V 10880 battery.
The cell is put in within the regular route – constructive finish towards the pinnacle.
The cell is fascinating. It’s two 10440 cells in sequence, however electronically they’re in parallel. I didn’t tear the cell all the way down to see it, however it’s an fascinating setup. Do NOT take this long-boi 10440×2 to imply that you should use two 10440 in sequence. You’ll be able to not. The driving force shall be sad and can set free the magic smoke.
Regardless of being primarily electronically the identical because the 10440 model, the output is a bit larger right here.
Low voltage safety was not noticed in any of the assessments, in order that’s an enormous draw back. It might be that the cell has safety, although, and the safety was tripped. I’m undecided tips on how to verify that. It did cost proper again up, although.
The temperature traces in these charts are included as common context, not exact measurements. The values symbolize the vary (min to max) throughout testing, however shouldn’t be taken as actual readings. A temperature sensor just isn’t all the time connected to the bezel (and even the most popular spot, assuming that might be outlined). Even with best placement, too many variables have an effect on temperature to definitively state a selected max worth.
Charging
Whereas the ReyLight Penlight MkII Aluminum itself doesn’t have charging, the included 10880 cell does. It almost has to, as a result of I don’t think about anybody has a bay charger that’d match this lengthy cell. Charging is by the use of a USB-C port within the constructive finish.
Charging is okay, if gradual. “Gradual” might be higher for this battery, although, and round 4 hours isn’t too lengthy to attend.
Modes and Currents
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens | Tailcap Amps |
|---|---|---|---|---|
| 100% (10440) | – | – | 324 (0s) 304 (30s) |
1.55 @4.2V |
| 20% (10440) | – | – | 96 | 0.43 @4.2V |
| 2% (10440) | – | – | 9 | 0.06 @4.2V |
| Moonlight (10440) | – | – | 0.3 | 0.01 @4.2V |
Pulse Width Modulation
Lots of the modes do use PWM, however in all circumstances, it’s very quick and unlikely to be seen.
Click on right here to see a “baseline” – a chart with virtually no mild hitting the sensor.
Then there’s the Ultrafire WF-602C flashlight, which has a few of the worst PWM I’ve seen. It’s so unhealthy that I used a put up about it to clarify PWM! Listed below are a number of timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make evaluating this “worst” PWM mild to the check mild simpler. That put up additionally explains why I didn’t check the WF-602C on the regular 50us scale.
Person Interface and Operation
The swap on the ReyLight Penlight MkII Aluminum flashlight in titanium is a mechanical clicky. It’s a reverse clicky, which suggests the modes might be modified whereas the sunshine is on. The swap has a tritium slot. 
One of many nice issues concerning the new tailcap is that it makes the swap a lot much less proud. It additionally makes tailstanding a lot firmer, too. The consumer interface really has some programming options. Mode reminiscence might be turned on or off (default is off, fortunately). There are a bunch of mode choices, too. Right here’s a consumer interface desk!
| State | Motion | Outcome |
|---|---|---|
| Off | Click on | On (Low, if mode reminiscence is off) |
| On | Click on | Off |
| On | Faucet | Mode advance (LMHT) |
| On | Faucet 8x | Enter programming mode^ |
^ Programming goes like this. As soon as in programming mode, the sunshine will blink as soon as, then blink in a short time (strobe-ish), then blink twice, then blink in a short time (strobe-ish), and so forth, as much as 5 blinks. With a purpose to program a sure function, click on through the “strobe-ish” part after the blink. Every of those blinks represents a programming choice, as follows:
First blink: Program the mode teams. Solely this selection has sub-options. On this choice, the sunshine will blink slowly 4x. The mode teams are as follows:
1 blink: (ML)-2%-20%-100%
2nd blink: (ML)-10%-40%-100%
third blink: (ML)-2%-10%-50%
4th blink: (ML)-50%-100%-strobe-SOS
To simply accept any of these 4 mode teams of your selection, click on after the suitable blink. So if you need the third choice, look ahead to the sunshine to blink 3x, and faucet the swap. You’ve programmed the third mode group. The sunshine will run the 4x blink cycle twice after which exit programming.
Second blink: Toggle mode reminiscence. Off is the default.
Third blink: Toggle moonlight mode. On is the default.
Fourth blink: Toggle mode order. Default is ascending. Could be toggled to descending.
Fifth blink: Reset to manufacturing unit settings.
LED and Beam
One of many updates on this ReyLight Penlight MkII Aluminum flashlight in titanium is that the sunshine makes use of a Nichia 519a. 
LED Shade Report (CRI and CCT)
CRI is properly over 90, and CCT is within the 4000K vary. Duv is barely detrimental, too, which actually simply makes this concerning the good emitter.
CCT (Correlated Shade Temperature) refers back to the measurement of the colour look of sunshine, expressed in Kelvins (Okay), which signifies whether or not the sunshine is heat (yellowish) or cool (bluish). A decrease CCT (under 3000K) is taken into account heat mild, whereas a better CCT (above 5000K) offers cooler, bluish mild.
CRI (Shade Rendering Index) is a measure of how precisely a light-weight supply renders colours compared to pure daylight. Scored on a scale from 0 to 100, larger CRI values point out that colours seem extra true to life and vibrant, much like how they’d look beneath the solar.
Beamshots
These beamshots all the time have the next settings: f8, ISO100, 0.3s shutter, and handbook 5000K publicity. These photographs are taken at ground stage, and the beam hits the ceiling round 9 toes away.
Tint vs BLF-348 (KillzoneFlashlights.com 219b model) (affiliate hyperlink)
I hold the check flashlight on the left and the BLF-348 reference flashlight on the suitable. These photographs are taken round 18 inches from the door.
I evaluate all the pieces to the KillzoneFlashlights.com 219b BLF-348 as a result of it’s cheap and has the perfect tint!
Abstract and Conclusion
I really like that uncooked aluminum is being provided! The beadblast end offers a pleasant, constant look, however I’m afraid it might be a little bit fragile (however no extra fragile than correctly uncooked aluminum). Output isn’t amazingly excessive, however it is amazingly excessive CRI and an amazing CCT. Almost good CRI, in truth! I really like that this mild helps the included 10880 cell and that it’ll additionally run two AAA, too. It’s an amazing choice for penlights, and cheap!!
The Huge Desk
^ Measurement disclaimer: Testing flashlights is my passion. I take advantage of hobbyist-level tools for testing, together with some I made myself. Strive to not get buried within the particulars of producer specs versus measurements recorded right here; A certain quantity of distinction (say, 10 or 15%) is completely cheap.
What I like
- Nichia 519a!
- 4000K!
- Excessive CRI!
- Aluminum (I don’t care a lot concerning the “uncooked” side, however it’s additionally neat.)
- Programming choices – mode teams, reminiscence or not, and many others.
- Helps each 1.5V and 4.2V cylindrical AAA-sized cells (however solely use the included 10880 for 4.2V!)
- Looks like tapping to straight entry turbo has been fastened within the Mk II version
What I don’t like
- No low voltage safety (as a result of it helps AAAx2).
