Preface
The Olight Seeker 2 Pro (Olight R50 Pro II) is the second iteration of the Olight R50 Pro model.
This is also Olight’s first flashlight that uses the 21700 battery (same battery type used in current Tesla Model 3 electric vehicle).
Let’s check out the merits and demerits of this new generation Olight Seeker 2 Pro model.
Packaging & First Impressions
This is what the light will come with as shown below.
- The shrink wrapped packaging with its magnetic opening flap looks premium – something not commonly found with flashlights’ boxes.
- The threads and o-rings were lightly lubricated. Threads were smooth and clean (no gritty feeling).
- The side electronic switch requires a fairly firm and deliberate press to activate and helps in preventing any unwanted activation of the light.
- Display indicator (8 LEDs Indicators) that shows Battery Level & Brightness Level is probably inspired by the Olight X9R model.
- Rubbery-style (Dermatoglyph Silicone) grip is Olight’s alternative to knurling for this flashlight.
- Magnetic tail cap is able to bear the light’s weight when attached vertically (upside down) to a flat ferrous metallic surface only. The heft of the flashlight prevents it from being attached horizontally.
- Anodizing of the light is uniform without any missing specs, as expected from Olight.
- No lanyard is provided, despite having a lanyard hole on the side of the tailcap.
- No clip is provided.
- A holster is provided and should withstand day-to-day abuse without issue.
- The holster comes with a quick release button for faster access to the light.
- The provided proprietary Olight 21700 battery (ORB-217C50) will not work in other flashlights.
- Battery compartment should be able to take other 21700 batteries that have a slightly thicker battery width.
- Inclusion of the L-dock (either by screw-in or 3M Tape) is great for indoor storage and charging for the Seeker 2 Pro.
- The self-adhesive Ply-yarn Drills are to help keep the Magnetic Charging Cable wire tidy when attached to the L-dock.
- The included microfiber cleaning cloth is a nice surprise – this is probably one of the rare occasion it is included with a flashlight.
- Scanning the QR code with your phone/tablet on the box’s bottom would bring up the Olight Seeker 2 Pro’s product page.
Note:
- Olight recommends using the 3M Tape to attach the L-Dock for short-term usage only. For long term installation, it is recommended to use the provided screws instead.
- Before using the flashlight for the first time, remove the Insulation Film from the battery tube.
- Only Button Top Batteries can be used, Flat Top batteries will not work in this flashlight.

UI (User Interface)
UI for this light is suitable for both Every Day Carry (EDC) or walking/hiking light as it is straightforward to use after the initial learning curve.
Switching ON and OFF is done by the side electronic switch on the light, so momentary activation is not possible.
Normal Operation
From OFF:
- 1 Click – Last brightness level (all modes except TURBO & STROBE are memorized only) is activated.
- 2 Clicks – Direct access to TURBO; 1 Click to switch OFF, 2 Clicks to return to previous mode or HOLD down to switch modes.
- 3 (or more) Clicks – Direct access to STROBE; 1 Click to switch OFF or HOLD down to switch modes.
- HOLD (~1 sec) – Direct access to MOONLIGHT.
From ON:
- 1 Click – Light will switch OFF.
- 2 Clicks – Direct access to TURBO; 1 Click to switch OFF, 2 Clicks to return to previous mode or HOLD down to switch modes.
- 3 (or more) Click – Direct access to STROBE; 1 Click to switch OFF or hold down to switch modes.
- HOLD – Mode change (light cycles through LOW, MID & HIGH only; MOONLIGHT & TURBO are not part of the sequence), release switch to select Mode.
Note:
- TURBO mode is memorized as HIGH mode.
- If memorized mode is HIGH mode, after 2 Clicks to enter TURBO mode – an additional 2 Clicks will return light to MID mode instead of previous mode (HIGH).
- There is 1 blinky mode for this light (STROBE only) and no SOS modes.
Timer Configuration
There are 2 types of Timers – Short (3 min) and Long (9 min). Light will switch OFF once the timer ends.
From ON:
- 2 Clicks & HOLD – 1 Blink indicates Short (3 min) timer is activated. Repeat 2 Click & HOLD to activate Long (9 min) timer – 2 Blinks.
Power/Battery Indicator
There is only 1 type of Power/Battery Indicator for this flashlight.
The Battery Indicator (4 LEDs) is the indicator on the RIGHT of the Side Electronic Switch.
After first switching ON the flashlight or when adjusting modes, the Battery Indicator will light up the following colors:
- 4 Green LEDs – Power is ≥75%.
- 3 Green LEDs – Power is <75%.
- 2 Green LEDs – Power is <50%.
- 1 Green LED – Power is <25%.
- 1 Red LED – Power is <10%.
For example, the below photo shows the Seeker 2 Pro’s Battery Indicator with its power at <50% but more than 25%.
Brightness Indicator
The Brightness Indicator (4 LEDs) is the indicator on the LEFT of the Side Electronic Switch.
After first switching ON the flashlight or when adjusting modes, the Brightness Indicator will light up the following:
- 4 Green LEDs – TURBO mode.
- 3 Green LEDs – HIGH mode.
- 2 Green LEDs – MID mode.
- 1 Green LED – MOONLIGHT or LOW mode.
For example, the below photo shows the Seeker 2 Pro’s Brightness Indicator to be either in MOONLIGHT or LOW mode.
Electronic Lockout
From OFF:
- HOLD (till MOONLIGHT is activated & deactivated) – LOCKOUT mode is enabled; HOLD (till MOONLIGHT is activated) – LOCKOUT is disabled.
When Electronic LOCKOUT mode is activated, any button presses will cause the RED LED on the switch button to activate for about 3 sec.
Form Factor
For flashlights that are intended to use on a daily basis (EDC) or walking/hiking usages and for possibly a long period of time, form factor is extremely important.
This light feels surprisingly well balanced in a medium sized hand (not head/tail-heavy). Switching between overhand and underhand holding method is easy with its form factor. The rubbery-style (Dermatoglyph Silicone) grip is Olight’s alternative to knurling for this flashlight and enables it to be extremely “grippy”, even with wet hands/gloves.
Due to the flat tailcap, the flashlight is able to tail-stand perfectly without the slightest wobble.
It fits the holster snugly and the quick release button helps for easy access to the flashlight.
Charging Process
With the provided Magnetic Charging Cable (MCC), the battery was charging at ~0.82A.
With the provided Magnetic Charging Cable (MCC) & L-dock, the battery was charging at ~0.83A.
The light is capable of operating on all modes when charging (at the expense of a slower charging rate). However, it is recommended to use “MOONLIGHT” or “LOW” only, to ensure that the battery does get charged.
Solid RED indicator on the TAIL portion of the MCC Charger depicts charging in progress.
Solid GREEN indicator on the TAIL portion of the MCC Charger depicts charging has completed.
Note: The included MCC cable and L-Dock is compatible with the existing models as well.
- S series: S1R, S1R II, S2R, S2R II, S30R II & S30R III
- M series: M2R
- H series: H1R & H2R
- Warrior series: Warrior X
Beam Style/Beamshots
For this light, the spill, corona and hotspot is somewhat predictable due to the TIR optic. The LEDs are partially covered under the TIR (Total Internal Reflection) optic. With the LEDs used, the beam is still relatively “throwy” for recognising items in the near to mid-range distance.
The above beam profile is a rough interpretation of what is seen when white wall hunting.
The beam has a fairly distinct hotspot with some slight corona and a fairly narrow (squarish style) spill, with most of the lumens output focused into the hotspot. It also helps that the LEDs are perfectly centred in this sample. There are some beam artifacts when white wall hunting but not visible in real world usage.
All of the beamshots taken below are done so with the following camera settings (MOONLIGHT: 1.3sec, F3.5, ISO100, 5000K WB, LOW: 1/2sec, F3.5, ISO100, 5000K WB, MID: 1/4sec, F3.5, ISO100, 5000K WB, HIGH: 1/10sec, F3.5, ISO100, 5000K WB and TURBO: 1/15sec, F3.5, ISO100, 5000K WB).
Some pictures have been adjusted slightly to depict as close as to what is seen in real life. The distance of the light from the door is 4.6m.

Mode (Output) Spacing
Mode spacing appears to be progressively brighter to the eye and the modes are well spaced enough to be able to know which mode one is currently in. With that in mind, TLR tend to view mode spacing as battery life indicators (amount of runtime left) rather than the specific output (lumens).
There is no moonlight level (sub-lumen or 1 lumen) option available as the “MOONLIGHT” mode comes in at 5 lumens. However, since this light is primarily targeted for those looking for a “Search & Rescue / Hiking or Walking” style flashlight, it is understandable why Olight may have thought otherwise.
On a side note, the HIGH mode (1200 lumens) could use a slightly lower output of say 1000 lumens to ensure a cooler & longer runtime – as the difference in output is almost imperceptible to most human eyes.
Tint & CRI
Olight did not disclose the tint (color temperature) and/or the CRI (Color Rendering Index) for the LEDs used in their light. For this light, a guesstimate would be in the 6000K and 70CRI ballpark.
However, there is slight tint shift in the beam profile. The hotspot is a cool white tint whilst the corona possess a slight yellowish green tint; and the spill having a slight purple tint.
This is not noticeable in real life usage.
Waterproofness
The light was subjected to warm water submersion, followed by cold water submersion and left under room temperature running water tap whilst running on TURBO.
No sign of water intrusion in the head, switch or tail was seen.
Lockout Capability
Both electronic lockout and mechanical lockout are possible when needed, like during transportation in a bag.
See UI (User Interface) – Electronic Lockout, on how to activate and deactivate Electronic LOCKOUT.
A quarter turn (clockwise) of the head section of the flashlight will enable Mechanical LOCKOUT.

Scale Comparison (Ruler)
Summary
To sum up, we believe that the most important part of any review is if given the chance to purchase the same light for our own EDC usage or to gift to our loved ones out from one’s pocket (wallet), would we still do it?
For this light, it is a YES, if the lack of a true MOONLIGHT mode is not an issue for your usage.
The straightforward UI with Direct Access to “MOONLIGHT”, TURBO or STROBE from OFF, Magnetic Charging Cable (MCC) capability with/without the L-dock, rubbery-style (Dermatoglyph Silicone) grip, Brightness Level Indicator, Battery Level Indicator, included accessories for the L-dock’s installation and complimentary microfiber cleaning cloth are all plus points for this flashlight.
However, as mentioned earlier, it would be nice if Olight includes a lanyard – especially since there is an existing lanyard attachment point on the side of the tailcap.
Here is a bonus size comparison with some of the other similar-sized flashlights we reviewed previously.
From Left to Right: Olight S2R II Baton, Oveready TorchLAB BOSS 70, Rofis MR70, Olight Seeker 2 Pro, Olight M2T Warrior, Olight Warrior X and Nitecore MH25GTS.
As with all gears, two is one and one is none.
