ReyLight Penlight Titanium Seigaiha Review
The ReyLight Penlight Titanium Seigaiha is a fun penlight by Rey. This light has a neat pattern, one Nichia 519a, and runs an included 10880 (or two AAA) cells!
Official Specs and Features
Here’s a link to the ReyLight Penlight Titanium Seigaiha product page.
Versions
Two versions of the ReyLight Penlight Titanium Seigaiha flashlight in titanium exist. There’s this stonewashed version, as well as a bead-blasted version. The Penlight, also with Seigaiha design, is available in brass and copper, too!
Price
As seen in this post, the ReyLight Penlight Titanium Seigaiha flashlight sells for $79.50. In fact, both titanium options are that price. Copper and brass cost a bit less, though!
Short Review
As it turns out, the ReyLight Penlight Titanium Seigaiha flashlight is practically like the other Seigaiha light I reviewed recently. The only difference is that this penlight runs one long 10880 cell (but it’s still 4.2V!) An additional part of that difference is that it’s possible to run two AAA cells in this light. I loved the Seigaiha 10440 light, and have to say, this long version is fantastic as well.

^ Measurement disclaimer: Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.

Package and Manual

Build Quality and Disassembly
Build quality of the ReyLight Penlight Titanium Seigaiha is good. It’s pretty typical of ReyLights, but the threads, even (or especially?) for titanium, are smooth.
But check out this Seigaiha pattern! Here’s more info on the pattern, which seems to be mostly just a nice decorative wave pattern. https://www.aisf.or.jp/~jaanus/deta/s/seigaiha.htm
The head has a tiny brass button. I believe the driver is screwed in.
Down inside the cell tube is a spring on the switch.
I have a couple other Pineapple Minis, but this is my first experience with the updated tailcap. I like it a lot! In fact, I strongly prefer this tailcap.
Both head and tail unscrew easily – nothing is locked down. The head and tail threads are not the same sizes, so unlike some other Pineapples I’ve had, the head and tail don’t screw together.
Size and Comps
Officially: 134.2mm length (including the switch button), Diameter: 15mm
If the flashlight will headstand, I’ll show it here (usually the third photo). If the flashlight will tailstand, I’ll also show that (usually in the fourth photo). 
Here’s the test light with the venerable Convoy S2+. The version below is a custom laser-engraved Convoy S2+ host by GadgetConnections.com. I did a full post on an engraved orange host right here! Or go straight to GadgetConnections.com to buy your Convoy S2+ now!
Also above is the light beside a new standard 18350 light! It’s not one I’ve reviewed yet but this is the CWF Arcadian Peanut in aluminum. This one is stonewashed and has the new Quantum Dragon driver – a whole new product! Stay tuned for a full review of this tiny powerhouse! Here are both the ReyLight Penlight Titanium Seigaiha flashlight and the AAA/10440 version of the Pineapple Mini in Seigaiha Titanium. The lights are similar/same other than the length (and thus, the cell(s) they take.) The heads are interchangeable! 
They use the same clip and clip parts, too.
Retention and Carry
The ReyLight Penlight Titanium Seigaiha flashlight in titanium ships with a collar-style clip installed.
It’s a deep (ish) carry clip – that is, it’s a deep carry clip if your pants will fit in the narrow shoulder you can see below. 
The clip has a nice open mouth and is finished very cleanly. The clip is not reversible, and as such, this light can’t be used on a hat. However, ReyLight does include a pocket clip “blank” that can easily be swapped in. You could run the light fine with the pocket clip removed, but a gap would exist between the tailcap and the body. So the stainless steel spacer is a very nice thing to have.
Power and Runtime
The ReyLight Penlight Titanium Seigaiha flashlight in titanium can run two 1.5V cells (double AAA), and also the included 4.2V 10880 battery. 
The cell installs in the normal direction – positive end toward the head. 
The cell is interesting. It’s two 10440 cells in series but electronically they are in parallel. I didn’t tear the cell down to see it but it’s an interesting setup. Do NOT take this long-boi 10440×2 to mean that you can use two 10440 in series. You can not. The driver will be unhappy and will let out the magic smoke. 
Despite being essentially electronically the same as the 10440 version, output is a bit higher here. 
Low voltage protection was not observed in any of the tests so that’s a big downside. It could be that the cell has protection, though, and the protection was tripped. I’m not sure how to check that. It did charge right back up though.
The light will also run two AAA batteries. In fact, it’s specifically because the light will run two AAA batteries (1.5Vx2, or 3V) that it doesn’t have low voltage protection! I did not test this at all, but this is probably the biggest difference in this version and the small version. When using one AAA in the small version, it’ll be at 1.5V. But when using two AAA in this version, it’ll be at around 3V, so the output will probably be some middle ground. Do be careful to use either brand new charged-even cells or married cells.
Charging
While the ReyLight Penlight Titanium Seigaiha itself does not have charging, the included 10880 cell does. It nearly has to, because I don’t imagine anyone has a bay charger that’d fit this long cell. Charging is by way of a micro-USB port in the positive end. 
Charging is fine, if slow. “Slow” is probably better for this battery though, and around 4 hours isn’t too long to wait. 
Modes and Currents
Modes and Currents

Pulse Width Modulation
Many of the modes do use PWM, but in all cases, it’s very fast and unlikely to be visible.
Here you can see a “baseline” – a chart with almost no light hitting the sensor. Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.
User Interface and Operation
The switch on the ReyLight Penlight Titanium Seigaiha flashlight in titanium is a mechanical clicky. It’s a reverse clicky, which means the modes can be changed while the light is on. 
The switch has a tritium slot. 
One of the great things about the new tailcap is that it makes the switch much less proud. It also makes tailstanding much firmer, too. The user interface actually has some programming features. Mode memory can be turned on or off (default is off, thankfully). There are a bunch of mode options, too. Here’s a user interface table!
| State | Action | Result |
|---|---|---|
| Off | Click | On (Low, if mode memory is off) |
| On | Click | Off |
| On | Tap | Mode advance (LMHT) |
| On | Tap 8x | Enter programming mode^ |
^ Programming goes like this. Once in programming mode the light will blink once, then blink very quickly (strobe-ish), then blink twice then blink very quickly (strobe-ish), and so on, up to five blinks. In order to program a certain feature, click during the “strobe-ish” section after the blink. Each of these blinks represents a programming option, as follows: First blink: Program the mode groups. Only this option has sub-options. In this option, the light will blink slowly 4x. The mode groups are as follows:
<
p style=”padding-left: 40px;”>1 blink: (ML)-2%-20%-100% 2nd blink: (ML)-10%-40%-100% 3rd blink: (ML)-2%-10%-50% 4th blink: (ML)-50%-100%-strobe-SOS
To accept any of those four mode groups of your choice, click after the appropriate blink. So if you want the third option, wait for the light to blink 3x, and tap the switch. You’ve programmed the third mode group. The light will run the 4x blink cycle twice and then exit programming.
Second blink: Toggle mode memory. Off is the default. Third blink: Toggle moonlight mode. On is the default. Fourth blink: Toggle mode order. Default is ascending. Can be toggled to descending. Fifth blink: Reset to factory settings.
LED and Beam
One of the updates on this ReyLight Penlight Titanium Seigaiha flashlight in titanium is that the light now uses a Nichia 519a. My brass Pineapple Mini uses a Nichia 219b, so it’s not bad at all. But I’d still call this 519a version an upgrade. 
There’s a glow glasket in the head – it’s very glowy, too! 
LED Color Report (CRI and CCT)
CRI is well over 90 and CCT is in the 4000K range. Duv is slightly negative too, which really just makes this about the perfect emitter.
Beamshots
These beamshots always have the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level, and the beam hits the ceiling around 9 feet away.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
I keep the test flashlight on the left and the BLF-348 reference flashlight on the right.
I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!
Conclusion
What I like
- Nichia 519a!
- 4000K!
- High CRI!
- Neat Seigaiha pattern
- Programming options – mode groups, memory or not, etc.
- Supports both 1.5V and 4.2V cylindrical AAA-sized cells (but only use the included 10880 for 4.2V!)
What I don’t like
- Sometimes the modes don’t seem to necessarily be in order (which has to do with the double tap turbo option)
- No low voltage protection (because it supports AAAx2).

Regarding the modes sometimes not being in the right order: some newer Reylights have a shortcut to Turbo where if you quickly double-tap the switch it jumps to Turbo from whatever mode you’re at. A tap after that then returns you to your place in the sequence before you hit turbo.
So the effect would appear like: full click to turn on and quick double-tap through M jumps to T, another tap returns to M-H-T-L-M-etc.
If you tap slowly through the cycle you won’t trigger the shortcut, but go fast enough and you’ll get a bright surprise.
My older Reylights do not have this and I prefer it because I can quickly jump to Medium and not accidentally blind myself with Turbo when I’m expecting Medium (especially on the Dawn!).
Edit: I just tested on all my Reylights and found 3 Turbo shortcut behaviors:
First: my oldest LAN has no Turbo shortcut. Tap as fast as you want and it goes in sequence as expected. My favorite.
Second: A mid-generation Pineapple Mini has a faster Turbo shortcut than described above where it only requires a full click and single quick tap to jump directly from Low to Turbo (it then curiously has 2 Turbo stops in a row after the shortcut). From OFF: LT-T-L-M-H-T-L. Many bright surprises with this one.
Third: the latest generations I have (Pineapple Minis with the tulip tailcap, LAN, Dawns, and the same double Seigaiha Pineapple you tested here) all require TWO quick taps after the first full click. From OFF: LM-T-M-H-T-L-M-H-T. Fewer surprises from this generation, but seems too long to really be a shortcut (only 1 less click than manually cycling to Turbo), but too short that it’s often triggered accidentally.
Phew, this comment got way longer than expected. Hope this helps!
Those are great observations, and yes, that’s definitely what I’m experiencing! Thank you for that. It explains a lot and also helps me avoid jumping to turbo!
