Olight Seeker 2 Pro Flashlight Review

Last Updated: October 13, 2022

Editors note: This flashlight is discontinued. It has been replaced by the Seeker 3 with an improved 4200 Lumen output.

The Olight Seeker 2 Pro is a small but powerful flashlight with excellent battery life. It’s a great everyday flashlight and a reliable option for a disaster situation — as long as you can recharge it.

If you’re looking to optimize size and weight with power and battery life, this is one of the best options on the market.

Let’s get into the details!

Specs and Buying Options

Length: 5″ | Battery capacity: 5,000mAh | Brightness settings: 5 | Output: 2 to 3200 lumens | Run-time:132 mins to 12 days

High-Level Summary

  • Proprietary battery

Gone are the days when having a bright flashlight meant lugging around something the weight of a large brick. The 21700 rechargeable lithium battery in the Seeker 2 Pro highlights just how far battery technology has come.

Despite its small size, it has a huge 5,000mAh capacity, giving longer run times than most of its competitors. In terms of capacity for size, this is one of the best flashlights you can buy.

The downside is that the battery is proprietary, which means you can’t replace it with a cheaper version. This shouldn’t be an issue if you’re using it day to day but might be a consideration if it’s part of your post-disaster kit.


Olight seeker 2 pro charging


The Seeker 2 Pro has a magnetic charger that attaches to the base of the flashlight with a 3.9 ft USB charging cable.

Olight also provides a handy L-dock which you can fix to a wall near a power socket. This is handy if you’re using it as an EDC flashlight, but it’s not an additional charger — you need to attach the magnetic charger to the top for it to work.

It takes around 6 hours to completely charge the battery using mains power and it can also be charged from a solar power bank.

If you’re thinking of charging in a disaster situation when there’s no mains power (e.g. using a solar panel), bear in mind that it’ll take a while to charge fully due to the battery capacity.

LED Brightness Modes and Run Times

The Seeker 2 Pro has five brightness modes (plus a strobe mode):

  • Turbo – 3200 lumens (dropping to 600 lumens)
  • High – 1200 lumens (dropping to 600 lumens)
  • Medium – 300 lumens
  • Low – 50 lumens
  • Moonlight – 5 lumens

While the turbo setting is super bright – useful if you need to dazzle an opponent – it only lasts for 2 minutes before dropping to the 600-lumen setting for an additional 130 minutes before the battery is drained. Using it on the high setting gives 110 minutes of bright light followed by another 30 minutes at 600 lumens.

This may not sound like very long but bear in mind that even the medium setting of 300 lumens will be plenty bright enough for most tasks, including night-time trekking on an established path. Using this setting, you’ll get up to nine and a half hours of light.

The low mode gives 52 hours of run time at a brightness of 50 lumens. This is bright enough for reading, moving around your home or campsite at night, and carrying out basic tasks.

At 5 lumens, the “moonlight” setting on the Seeker 2 Pro is kind of bright. Typically a moonlight setting is around 1-2 lumens — just enough to help you find your way to the bathroom or get a midnight snack without waking your significant other.

It’s a shame the Seeker 2 Pro doesn’t have this minimal light setting, but this may not bother you if you don’t need this setting (or don’t mind waking your partner up!). On the plus side, the battery will last a full 12 days on this lowest brightness setting.

Accessing the different brightness settings is done through a single power button that scrolls through the settings. You can access the turbo mode directly by double-clicking.

Build Quality and Durability

You’d expect a flashlight at this price point to have excellent build quality and fortunately, that seems to be the case. It’s rated to IPX8 so you don’t need to worry if it accidentally ends up in the bath or toilet bowl.

The only slightly disappointing aspect is that it’s only drop rated for 1.5 meters.

While this doesn’t mean it’ll break if you drop it from a greater height, it would have been nice to see a higher rating of 5 meters, which would bring it in line with other high-quality EDC flashlights.

However, boosting the durability could arguably mean a larger, heavier flashlight — there’s always a trade-off!

Additional Features

The power switch is ringed by two sets of four lights. One set shows you what brightness mode you’re using (turbo, high, medium, low/moonlight). The other set gives you an indication of battery life. These are subtle but effective and look pretty stylish to boot.

The flat magnetic base allows you to easily stand the Seeker 2 Pro upright or attach it to a metal surface. There’s no belt clip on the torch or holster, which is a bit of an annoyance, but not a deal-breaker for most people.

On the subject of the holster, it gives a pretty snug fit and is reasonably robust. It fastens with a buckle rather than a hook-and-loop tab, but there’s a quick-release button for fast access.
