I was sent this light to review free of charge but, as always, I've tried to be as unbiased as possible.


If you're a flashaholic who wants a new flashlight that feels good in the hand and has lots of neat features, then listen to this.
Olight's hottest flashlight is the Seeker II Pro. Everyone's favorite black and blue flashlight manufacturer is back with a light that answers the question, "But what if an 18650 cell is just a little too small?"
This flashlight has everything.

- Triple XP-Ls
- A 5000mAh 21700 cell
- Battery charge and mode indicator LEDs
- A TIR optic that melts if you burn too much cardboard

And what's that in the tiny box at the bottom? It's an L-Dock!

"What's an L-Dock?"

It's that thing of when you screw an L shaped piece of aluminum to your wall so you can charge your Olight flashlights without taking up your valuable table space.

The Seeker II Pro comes in one of Olight's textured white boxes, but with the fancy addition of a magntic lid. It's a cool box, but I'm embarrased to say that it took me a good twenty seconds to figure out how to get the thing open. Upon opening the package, a bright yellow plastic sheet reminds you to remove the insulating film and fully charge the flashlight before use. The contents of the box are organized into sub-boxes.


The box contains:

  • An Olight Seeker II Pro
    - A holster
    - A proprietary protected 5000mAh 21700 cell
    - A "MCC1AL" magnetic charging cable
    - An "L-dock"
    - Hardware for mounting the L-dock
    - A microfiber cloth(?)
    - A manual (page 1, page 2)


If you've ever handled an Olight product, you'll know what to expect from the Seeker II Pro. The anodizing is smooth and perfect, the machining is clean, with no defects or milling marks visible, the threads are square cut and pre-lubed, the bezel and switch boot ring are blue, the TIR optic isn't covered by and glass, et cetra. It's like an S2R, but larger and more complex.

Starting at the tail, The Seeker II Pro has one of Olight's standard magnetic charging attachment points. Unforunately, because of the limitations of current magnet technology and the size of this light, the Seeker II Pro's tailcap magnet can't support its own weight. It's strong enough to suspend vertically if you stick it to a flat surface, but don't even think about sticking it to a vertical surface. It's not gonna happen.

The tailcap has a line pattern machined into it to make it easier to unscrew. This becomes more necessary as the diameter of your flashlight increases. There's also a lanyard hole in the tailcap, but, shockingly, no lanyard was included. That threw me for a loop, as every Olight I've reviewed that has a lanyard hole has come with a lanyard. Maybe they just ran out of space in the box.

The inside of the tailcap is a bit more complicated than the past magnetic charging lights, a theme that we'll be revisiting in a couple paragraphs. The contacts are slightly different, and it doesn't have a retaining ring. I think it's press fit, actually.

The body tube has no knurling, with a flat spot for the logo an SN. The reverse side has polarity indication marks. To make up for the lack of knurling, Olight added rubber grip pads to the body tube. They're textured, and even have shallow grooves for your fingers. Very fancy. Olight's done finger grooves before on their X7R and X9R, but this is the first light they've done that on that's below $250.

The head of the Seeker II Pro is where the majority of the fancy stuff resides. The bezel is in Olight's typical blue, with light crenelations. It screws off to reveal a gasket, the TIR optic, and a white plastic piece that holds the optic in place.

Underneath all of this is a triple MCPCB with three XP footprints in series.

I managed to melt the optic slightly while messing around and burning cardboard, so be wary of that if you also enjoy making questionable decisions. (Edit: Also, because of the dark colored synthetic holster, if it were to come on in there, it would melt the holster very quickly, that molten plastic would collect on the lens, and the light would weld the holster plastic to the lens permanently, or at least mess it up real bad.)
The head has a good amount of thermal mass and some heat fins around and in front of the button. The button itself is rubber and has the usual blue ring around it, but this ring has eight holes in it, which are lit by eight green LEDs. These indicator lights tell you your remaining battery power and the current mode that your Seeker II Pro is on. This is a feature that Olight's implemented on the X9R, which is over four times more expensive.
On the battery side of the head, you can see an unusual battery contact. It's not a traditional spring, and it's not a brass button. It's a gold(?) plated metal contact that provides a little bit of springiness, but not a lot.

I've never seen this before, and I don't know why it's there instead of something more traditional. I suppose when your flashlight can only be used with one specific cell, you don't have to account for variations in battery size.
Overall, the only problem I have with the build quality is the lack of a glass lens. Everything else is very well done.


The included hoslter is made out of synthetic black fabric, with some softer fabric on the inside. It's held closed with a plastic clip.

The reverse side has a two part strap, so you can attach it to your belt by either sliding your belt between the inside strap and the holster, or by using the outside strap, which snaps into place.

There's also a D ring above the straps, though I don't know why it's there. I'm also confused by the purpose of those holes in the top and bottom of the holster. Drain holes, maybe?

Overall, it seems well constructed to me.

Microfiber Cloth

The Seeker II Pro comes with a 6" by 6" microfiber cloth (that's 15.24 cm by 15.24 cm for you non-Americans) in a little sealed pouch. It's not a high quality microfiber cloth, but when I wiped my phone with it it did get rid of the fingerprints. I'm really not sure why it was included.

Battery and Charging

The Seeker II Pro comes with a 5000mAh 21700 cell. I removed the wrapping to find that it was an LG M50, which, to my surprise, was only rated for a max continuous discharge rate of 7.3A. I expected a lot more, considering it was a 21700 cell.

The battery level is displayed with four small LED indicators next to the switch.

The top indicator lights when the battery percentage is between 100% and 75%, the the second to top is for 75% to 50%, the next is 50% to 25%, and the bottom indicator will show green between 25% and 10%. If the percentage of battery power remaining is less than 10%, the bottom indicator will glow red. The battery status is displayed for about 7 seconds after turn-on, and after any mode changes.
The Seeker II Pro charges with one of Olight's magnetic charging cables. With the included cable, the light charges at 800mA. That's not very fast for such a large cell. It would take over six hours to completely charge the cell.

The included L dock can be screwed to your wall with included hardware. It does come with adhesive backing, but the manual makes it very clear that they don't intend for you to just use the adhesive backing. I didn't test the dock when mounted to a wall, as I don't know where I'd want to mount the thing.

The flashlight is meant to hang from the magnetic dock, and the charging cable attaches to the top. This dock will not function without a charging cable.

Modes and UI

The Seeker II Pro has Olight's standard UI. From off,

  • Click and hold to go to moonlight
  • Click to go to the memorized mode
  • Double click to go to turbo
  • Triple click to go to strobe
  • Press and hold for a long time to lock the light out

When on,

  • Double click to go to Turbo
  • Triple click to go to strobe
  • Click and hold to loop Low -> Med -> High
  • Click to turn off

The current mode is indicated by LEDs next to the switch, on the opposite side of the battery indicator LEDs. The bottom LED is for moonlight and low, the next is for Med, then high, then turbo.
One of my main gripes about the Seeker II Pro is the lack of a proper moonlight mode. The lowest mode is 5 whole lumens for goodness sake. I get that on a non-EDC light, moonlight modes aren't usually important, but with this specific flashlight and its wall mounted charger, where you can have it at the ready whenever you need it, moonlight mode would be handy. Sure, if there's a bump in the night, you're going to take it straight to turbo, but I'm a whole lot more likely to need it for getting up to pee, and I want 0.1 lumens or less for that.

Beam and Tint

Firstly, this thing is *bright*. 3200 lumens out of this small of a head, as I'm sure you're all aware, is a lot of power, and it's easily capable of melting things. "Things", in this case, includes its own optic. To be fair, I was burning cardboard when it happened, but like I said before, the lack of a glass lens is just silly for a light this powerful.
Moving on, the Seeker II Pro houses three cool white XP-L emitters behind a triple TIR optic. These make a pretty standard TIR beam, with a large hotspot and some much dimmer spill. I'm not a fan of the color temperature, but the flashlight I got doesn't have any green in the beam, and tint shift is minimal, with the spill being a bit bluer than the hotspot.

Modding potential

Disclaimer: Do this stuff a your own risk. If you mess up and break something, that's on you. Also, doing any of this will totally void your warranty.

Driver: ???
MCPCB: 26mm, XP footprint, 3S

It's only pushing about 3A through each emitter, so you can swap in whatever. Some LH351Ds, maybe?

Bottom line:

  • Excellent build quality
  • Large battery
  • Full package
  • Very bright
  • UI shortcuts


  • Proprietary cell
  • Slow charge rate
  • Cool white
  • No glass lens over the optic
  • Lowest mode is 5 lumens

Thanks for reading my review! If you have any questions about this flashlight, I'd be more than happy to answer them.

It’s probably the best designed premium feature packed flashlight I’ve seen. The only reason I didn’t buy it during the initial promo was the lack of a NW option.

I love the grip, I love the format, and I love the indicator LEDs, but not the lack of a glass lens…
Mine is now equipped with 3D XP-L HI (from my FW3A) for a better tint and a bit more throw (and 700 lumens less of course).
