So, what are these differences, and what makes the Seeker 3 pro stand out from the rest? That’s precisely what we’ll go through in this review. This review will cover the specifications and capabilities of the Seeker 3 pro in detail so you know exactly what you are buying.

Olight Seeker 3 Pro Packaging and Flashlight Use

Upon purchasing your Olight Seeker 3 Pro, you can expect a clean and simplistic white box containing your flashlight. The package outlines special features and is very easy to open.

After opening the box, you will immediately notice Olight’s thorough packaging and accessories. Inside the box, you can expect to find

  • Olight Seeker 3 Pro
  • Holster
  • 5000mAh Olight 27000 battery
  • MCC3 magnetic charging cable
  • Instruction manual

This bright flashlight itself has a slick, black design. Constructed with smooth aluminum alloy and features a rubber grip along the handle. The rubber is enhanced with grooves and stippling to provide the most comfortable and secure grip. 

The flashlight is solid and sturdy, featuring no detachable parts besides the tail cap. The tail cap features a lanyard mounting point to clip into for extra security and convenience. 

The Olight seeker pro 3 features a rotary knob that increases or decreases output with a simple turn. Olight claims the flashlight’s dimming is step-less, meaning the knob will turn seamlessly and allow micro-level adjustment. 

Pressing the knob unlocks the unique modes included with the Olight Pro Seeker that I will cover further below.

Olight Seeker 3 Pro Specifications 

The Olight pro seeker features many intricate and exceptional specifications that make it truly special. 

The major notable upgrade of the Olight Seeker 3 Pro is the 31% increase in lumens, shined by the four high-performance LEDs. 

The powerful beams’ maximum distance is 820ft or 250 meters. Especially at night time, this flashlight can light up a vast space instantly. See a real-life demonstration of the fantastic power of the Olight Seeker 3 Pro in this short

Due to this flashlight’s incredible power and range, the maximum runtime in turbo mode is slightly shorter than some weaker flashlights.

The Olight Seeker 3 Pro warranty falls into the 5 year warranty section on Olight’s website. Olight promises to return any defective or damaged items, no questions asked, and will cover the shipping costs for returns.

Olight follows a 30-day return policy where you can return your order for any reason within 30 days of the order being received. Your item must be new, unworn, and in the original packaging to receive a refund.

Build Quality

The build quality of the Olight is top-of-the-line with a smooth black aluminum finish. The product has clean edges and lines with no chips and high resistance to anodization.

The silicone grip is designed to withstand wetness and lines the entire handle portion. With a medium-sized build, the nearly full palm of your hand will have a secure grip.

The central knob that controls the output works seamlessly and smoothly. Rotation can take a while to get used to, but it helps you ensure just the right amount of light. I recommend not turning the knob too fast to ensure proper calibration. 

Lens, LED, Reflector, and Bezel

The four high-powered led lights are covered by layered TIR optic lenses creating an incredibly sharp and focused ray. The light is more concentrated with angled reflectors fitted perfectly underneath the lens.

This LED flashlight also features a smooth circular bezel to create a clean, rounding effect on the light providing a definitive edge. The bezel is a soft blue color on the black version of the light. 

Another unique safety feature the Seeker 3 pro offers is the built-in thermal and proximity sensors. If any overheating or lens obstructions occur, the light will automatically lower the output to prevent fire hazards. This feature can be turned off by following the instructions in the manual. 

Size and Dimensions

The weight of the Olight Seeker 3 Pro is 7.06 oz with the battery and 4.5 oz without. As a medium-sized flashlight, this is a relatively lightweight option.

The length is 5.2 inches and features a head diameter of 1.38 inches. While perfectly sized for its holster, which features attachment options, the flashlight may not fit into shallow pockets.

The body diameter is 1.10 inches, and the tail cap diameter is 1.17 inches. The thin diameter allows for a tight grip with a jutted backstop in the form of the tail cap to prevent slipping.

Seeker 3 Pro Modes

The Olight Seeker 3 Pro features six modes set at different increments, similar to the Olight warrior 3 tactical flashlight

The modes and their strength are as follows:

  1. Turbo (4,200~1,200~600 lumens)
  2. High (1,200~600~300 lumens)
  3. Medium (300 lumens)
  4. Low (50 lumens)
  5. Strobe (13 Hz at 4,200 lumens)
  6. Moon (5 lumens)

To turn on the light, simply press the knob once. If your seeker pro has locked, you must turn the rotary knob clockwise more than 90 degrees to unlock it. 

The Olight Seeker 3 Pro has a memory feature meaning that the light will return to the last mode used before being turned off. Upon first use, the flashlight will start at low. 


When off (and unlocked) 

  • Double-clicking the button will turn the flashlight on in turbo mode. (Another double click will return it to the previous mode used.)
  • A triple click will turn the flashlight on in strobe mode. 
  • A press and hold will turn it on in moon mode.


If your Seeker 3 pro is already on

  • Turn clockwise to increase the brightness levels
  • Turn counter-clockwise to decrease the brightness
  • One-click turns the flashlight off. 
  • A double click will turn to turbo mode
  • Triple click for strobe
  • Press and hold to cycle through low, medium, and high modes
olight seeker 3 magnetic charging


The Olight Seeker 3 Pro has a battery included. This battery is a customized 3.6V 5000mAh 21700 lithium-ion battery. This battery packs a punch for its size and weight compared to other 18650 batteries. 

One downside of this custom battery is that it can not be replaced with another normal 21700 battery. 

The Olight Seeker 3 Pro features magnetic charging like the Olight warrior pro. The flashlight comes with an MCC3 USB magnetic charging cable. A full charge from 0 battery takes around 5 hours. 

One notable feature of the Olight Seeker 3 Pro is the battery level indicator next to the rotary knob. This lets you know exactly how much battery you have left so you can conserve and charge when needed.

The indicator works as follows:

  • 4 bars- 75-100%
  • 3 bars- 50-75%
  • 2 bars- 25-50%
  • 1 bar- 10-25% (At this level, the bar will turn red)

Lock Out Mode

A smart safety feature of the Olight Seeker 3 Pro is the automatic lock-out mode installed in the flashlight. The Seeker 3 pro will automatically lock after 30 seconds of non-operation or being turned off.

This feature ensures safety and prevents accidental battery consumption. If any movement accidentally turns or presses the knob, this feature will save you from battery waste!


With such a powerful battery, the Olight Seeker 3 Pro has the potential to outlast many of its predecessors, including the  Warrior mini 2, S2R Baton 2, and Baton 3. 

Although the battery is much more powerful, the weight and size are reasonable. Despite its massive output potential, this allows for effortless storage and handling of the Seeker 3 pro.

The maximum runtime varies by mode.

  • Turbo- 2.5+127+35 minutes
  • High- 135+35+10 minutes
  • Medium- 640 minutes
  • Low- 55.5 hours
  • Strobe- ~45 minutes
  • Moon- 15 days

Throw Measurement

The throw measurements are extremely impressive for this flashlight. You will feel the pronounced reach of the beam in any setting. 

The max distance for each mode is as follows:

  • Turbo- 250 meters
  • High- 130 meters
  • Medium- 65 meters
  • Low- 25 meters
  • Moon- 0 meters
