Today I have in my second Olight for the week. It’s not necessarily a bleeding-edge new model, but the Seeker 2 is a still-available, still-relevant 21700 light worth having a test of. Read on!
Official Specs and Features
Here’s a link to the official product page.
Versions
There are a few versions, including a Seeker 2 Pro (which I’ll also show below). What I have here is what I’d call the “base model” Seeker 2 – not the limited edition blue, and not the Pro, and certainly not the orange Pro limited edition… Essentially the Seeker 2 black and Seeker 2 Pro black are still avaialble.
Price
These (as reviewed) go for $109.95. That’s just for the standard edition, but there are a couple other limiteds. Those are generally unavailable at this time.

Short Review
This is a nice light. Easy UI and general user friendly design. The proprietary 21700 cell is something that users should rail against but Olight is going to keep making what sells – and their lights sell. And this being the “2” of the Seeker is worthwhile noticing, because the R50 Seeker (which I reviewed ages ago) also has a proprietary cell and built-in charging.

- Measurement disclaimer: I am an amateur flashlight reviewer. I don’t have $10,000 or even $1,000 worth of testing equipment. I test output and such in PVC tubes!! Please consider claims within 10% of what I measure to be perfectly reasonable (accurate, even).

Package and Manual
Build Quality and Disassembly
The feel of the Seeker 2 is a bit unusual. The anodizing has some of the chalky feel of Armyteks and none of the glossy feel Olights usually have. But it’s a nice middle ground between “too chalky” and “plenty grippy due to matteness.”
There are blue appointments which add a nice look – the switch shroud and the bezel are two examples.
The tail end is dominated by the charge port. I can read voltage off this when a cell is inserted, but I haven’t tested it’s liveliness with any steel wool….
The blue bezel does appear to be removable but my attempts did not prove fruitful. This is likely screwed in, but might also be press fit (which wouldn’t be out of the question for Olight).
There’s minimal, but prominent branding.
The tailcap has nice reeding which provides good grip. You may never need to remove the cell though, because it’s proprietary and the light has charging, and regular 21700 cells aren’t going to work anyway.
If you do decide to remove the tailcap though, you’ll have a good experience. The threads are smooth, thick, square cut, and well lubed.
The head and tail appear to not have springs, but what’s there is slightly springy.
Size and Comps
Official dimensions:
Weight: 185g/6.53oz
Length (mm / in) 126mm/ 4.96in
Head Diameter (mm / in) 35mm/1.38in
Body Diameter (mm / in) 27.5mm/1.08in
Retention and Carry
All you really get is the lanyard and the mount point seen above There’s no pocket clip or pouch or anything with the Seeker 2.
Power and Runtime
The Seeker 2 is powered by a single liion cell. One is included, and it’s proprietary. There are normal contact points but the positive end has a negative ring exposed too – and this is where the light makes contact. The cell is a 5000mAh 21700. Non-proprietary cells will not work in this light!
The cell will also not work in chargers. There’s a little shield on the positive terminal, and the positive connection itself is recessed enough that most (all?) chargers will not make contact with this. So you’ll have to charge this in the light.
The cell also does not go in the light in the “normal” way (positive end toward head). It’s backward, but this is a thing Olight does fairly often – the positive end goes toward the tailcap).
Here are a couple of runtimes. Turbo steps down after 3 minutes, as stated will happen in the manual. The stepdown is to a much higher level than quoted though (claim: 600 lumens). Eventually the light steps down more and then shuts off. LVP is around 2.8-2.9V, which is good. The switch does warn of LV along the way, too.
Output on High is very similar in duration and stepdown profile, including the shutoff. It can be said based on this runtime that Turbo steps down to High, and so on.
The switch indicates during runtimes too, most notably that the switch will blink red when voltage is low (and when the light has switched to the very lowest of its stepdowns.) More as follows:
Green: >60% charge
Orange: 10-60% charge
Red: 5-10% charge
Flashing red: <5% charge
On-board charging is by way of a USB to magnetic-proprietary connector.
Despite having many lights that use a connector that looks like this, it’s not a guarantee that this one will work with any other Olight you have with a magenetic charge base (!!!). So keep your Olights organized well.
The charge connector on the light is on the tail, and while it is magnetic, it’s not really magnetic enough to hold the light securely in places.
The charge base snaps to the light very willingly, and the light may be stood on the charge base easily.
Charging is claimed at 1A, and since what I’m measuring is the 5V wall output, 1A is probably not wrong. Charging at 5000mAh cell at 1A is kind of slow, but good for cell health.
During the charge, the charge base indicates whether charing is happening (red) or charging is complete (green).
Modes and Currents
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens | Tailcap Amps |
|---|---|---|---|---|
| Turbo | 3000/600 | 3m/155m | 3328/~1350 | 6.42 |
| High | 1200/600 | 110m/50m | 1363/~650 | 1.90 |
| Medium | 300 | 13h | 341 | 0.41 |
| Low | 50 | 72h | 58 | 0.08 |
| Moon | 5 | 15d | 6 | 0.02 |
PWM
For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor. And here’s the worst PWM light I have ever owned. Also one of the very first lights I ordered directly from China!
User Interface and Operation
There’s a single switch on the Seeker 2. It’s an indicating e-switch on the head. It’s a very good sized switch, and while mostly black, has a tiny transparent dot in the center. The dot is used for indication and can be green, orange, or red.
Here’s a UI table!
| State | Action | Result |
|---|---|---|
| Off | Click | On (Memorized Mode, Turbo Excluded (Turbo memorized as “High”)) |
| Off | Hold | Moon |
| Any | Double Click | Turbo |
| On | Hold | Mode Advance (LMH) |
| Turbo | Double Click | Previous Mode* |
| Any^ | Triple Click | Strobe |
| Strobe | Click | Off |
| Strobe | Hold | Low |
| On | Double click and hold | Set timer for current mode: One blink is the 3 minute mode. Double click and hold again for the 9 minute mode (indicated by two blinks) |
| Off | Hold >2s | Moonlight then Lockout. Clicking switch during lockout activates the red switch, for notification. |
| Lockout | Hold >2s | Unlock |
- This is always an “on” state since really the double click from off first turns the light on to the previously used mode, then reaches Turbo. Also “High” is memorized in this case as “Medium” (a bit inexplicable….).
^ The manual states that the light must be on, but in practice off works too.
LED and Beam
The emitters here are three Osram P9 emitters, though I don’t believe the manual actually states this. The light has a three part TIR, and provides a nice fairly tight beam.
These beamshots are always with the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure.
Tint vs BLF-348 (Killzone 219b version)
Test light is on the left!
I compare everything to the Killzone 219b BLF-348, because it’s inexpensive and has the best tint!
Conclusion
What I like
- Very good build quality
- Complete package
- Charging seems reliable
- Meets specifications for output and throw
- Basic aspects of the UI are very simple and mostly straightforward
What I don’t like
- Proprietary cell and other cells won’t work
- Osram P9 leaves something to be desired regarding color temperature
- Fringe aspects of the UI are a bit convoluted
