ReyLight Dawn Aluminum 18350 Flashlight Review
Here’s the ReyLight Dawn flashlight made of aluminum and running one 18350. This triple-emitter light has many tritium slots and a great user interface!
Official Specs and Features
Here’s a link to the official product page.
Versions
Many versions of the ReyLight Dawn exist. I’d consider this to be a “new” version though – name it how you like. Namely, it’s different in that the 18650 version uses a completely separate body from the 18350 version. Older versions used an extension tube – more on that later!
Since ReyLight is moving shops (as far as I understand) and selling out current inventory (as far as I understand) for a two-for-one deal, I can’t locate the Dawn Aluminum 18350 flashlight on the website to be able to identify all the options. I believe there are three (red, black, blue) or so colors of the aluminum version, and it’s available in 18650 and 18350 format.
Price
Again, I can’t find this Dawn on the ReyLight website, but I think it retailed for around $69. (Confirming using the wayback machine here.) The 18350 version is $69 and the 18650 version is $79.
Short Review
I always appreciated the 18350 version of the ReyLight Dawn. This aluminum version is great too – aluminum is one of the best materials for flashlights. The blue color (and other colors too, for that matter) looks great. I love the emitter choice on this Dawn. The user interface is great. That this Dawn offers many tritium slots is great. This is just a great light!

^ 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
No manual is included.
Build Quality and Disassembly
I have always appreciated the Dawn. Let me add right here and upfront why I never owned one. The extension tube that allowed the use of n 18650 cell had a frag pattern that didn’t align with the main body. That was simply a deal breaker for me. BUT! Rey (of ReyLight) has fixed that with this aluminum iteration. And he fixed it in a way that I actually appreciate, too – the 18350 body (seen in this review) and the 18650 body are completely separate bodies! No more extension tubes.
To be clear, I actually like extension tubes just fine. For a while, I wished that’s what the TorchLAB BOSS had used. But separate bodies have grown on me and I really like them now.
On to the ReyLight Dawn Aluminum 18350 flashlight specifically. This light is well-built and also quite attractive. The blue really pops!
Both head and tail have a nice spring – the head has what I’d call a “q-lite” spring, but that’s not a bad thing for this application.
Check out the body – that frag pattern (maybe not the official name, and not exactly a frag pattern as used by other makers) looks great and notably is all lined up properly (which makes sense, because it’s just one piece there.) The head has some cooling fins that are fairly shallow, but check out all those tritium slots!! You’ll get a better view later, but those are peekaboo slots; they’ve visible from the front, too!
Size and Comps
I don’t see any official dimensions, but I measure the light at 25mm in diameter and 80.63mm long. The weight with cell is 92g.
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+. Mine’s a custom “baked” edition Nichia 219b triple. A very nice 18650 light.
Also above is the light beside my custom engraved TorchLAB BOSS 35, an 18350 light. I reviewed the aluminum version of that light in both 35 and 70 formats.
I happen to have the 18650 version of the Dawn too, so you can see some size comparisons below.
Here’s another recent addition “from Vosteed” but really a ReyLight product too (they acknowledge that; it’s not a secret.) Quite similar lights, really.
Retention and Carry
A pocket clip is included and attached to the ReyLight Dawn Aluminum 18350 flashlight.
That’s the standard ReyLight stainless steel pocket clip, and I really like it. it has a nice big mouth, nicely smoothed edges, and just overall great utility. It’s held in place by two Torx screws, and I believe it has “standard” hole spacing.
Also included is the orange plastic case that’s shown above.
Power and Runtime
Power to the ReyLight Dawn Aluminum 18350 flashlight is from an included 18350 cell. This cell is a flat-top and seems standard.
The cell goes into the Dawn in the usual direction – the positive end goes toward the head.
Below are a couple of runtime graphs.
The light does seem to have low voltage protection, which kicks in around 3V.
Modes and Currents
For this table, I tested only the default mode groups.
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens | Tailcap Amps |
|---|---|---|---|---|
| 100% | 1800 | – | 1280 | [MAX] |
| 20% | 360 | – | 261 | |
| 2% | 36 | – | 38 | |
| Moonlight | – | – | 0.67 |
Pulse Width Modulation
PWM is present on the higher three default modes. It’s fast though, and you’re very unlikely to be able to see it (without a scope).
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
On the ReyLight Dawn is a reverse mechanical clicky switch. The switch has a metal cover, and as stated above, three tritium slots.
The switch is very much like many other ReyLight flashlights, including the recently reviewed Rook (by Vosteed).
Here’s a user interface table! The user interface is actually the same as is used on some ReyLights, including the LANapple I recently tested.
| State | Action | Result |
|---|---|---|
| Off | Click | Moonlight^ |
| On | Click | Off |
| On | Half Press | Cycle modes (Moonlight, 2%, 20% ,100%)^^ |
| On | Tap 8x | Enters programming mode^^^ |
| On | Hold briefly | Return to Moonlight |
| On | Double tap | Turbo |
^ If the light is turned back on soon after turning off (within a couple of seconds), the previous mode will be remembered. If more than 2 seconds, the light will turn on into Moonlight.
^^ The light is user programmable, so only the default output levels are listed here.
^^^ In programming mode, the emitter will blink, then strobe. There are five selections a user can make in programming mode. The selections follow a “blink then strobe.”
The first group blinks once then strobes. This is the mode group selection.
The second group blinks twice then strobes. This is the memory toggle.
The third group blinks three times then strobes. This is the moonlight toggle.
The fourth group blinks four times then strobes. This is the mode order toggle (lowest to highest or highest to lowest).
The fifth group blinks five times then strobes. This is the factory reset option.
To interact with any of the programming options, you must tap during the strobe section following that option. So to toggle the memory, first enter programming, then wait until the strobes after the second blink. Tap the switch. I did say “tap” but a full click probably works just fine too.
LED and Beam
What I have is the Nichia 519a version. Since I can’t really access the Dawn product page, I can’t say whether that’s all you could get other emitters or not, but I do know Rey has offered many (most recently Cree XP-L HI, in the Rook). Either way, this 4000K 519a is what you probably want anyway.
The “4000K” is maybe a touch warmer than you might have expected.
LED Color Report (CRI and CCT)
As with most (all?) the other Nichia 519a emitters I’ve tested, both CRI and CCT are great. CCT comes in below the claim, at between 3500K and 3800K. For me, that’s great. If you wanted something more neutral though, this might be too warm for you. CRI is great, and nearly “perfect.”
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
- Uses Nichia 519a
- Nearly perfect CRI
- Warm white (at around 3800K)
- Good user interface (somewhat programmable)
- Uses aluminum (which brings the cost down from the older titanium versions)
- The “hold for moonlight” option
What I don’t like
- Output is dependent upon the cell being used
- Not available as a “kit” with one head and both size bodies
- So much of the optic is covered by the flashlight body (I want a larger opening for light to escape)
