I’ve tested many of the best torches over the years, but the Olight Seeker 4 Pro caught my eye for its blend of high power and smart design features.
Boasting a maximum output of 4,600 lumens, it claims to deliver serious performance while being compact enough for everyday carry (EDC).
After putting it through its paces in various settings, from camping trips to late-night hikes, I found there’s a lot to like about this flashlight – but a few quirks worth noting, too.
It's a bit larger and definitely more powerful than the highly-rated Olight Baton 4, making it a solid option for everyone who needs a reliable, premium hand torch.
Olight Seeker 4 Pro review
Price and availability
The Olight Seeker 4 Pro comes in at around £140/$140 (Olight UK/ Olight US), which places it in the higher price bracket for EDC torches. For this price, you get a well-rounded package: the torch itself, a holster (with the USB-C charging port), and a sturdy build that feels like it could survive the apocalypse.
Specifications
- Weight: 205g/ 7.23oz
- Maximum light output: 4,600 lumens
- Beam range: 260 metres
- Waterproof rating: IPX8
- Power: Rechargeable, USB-C
- Runtime: up to 15 days (in ‘Moon’ mode)
Design and build quality
From the moment you pick up the Seeker 4 Pro, you can tell it’s built to last. The aluminium alloy body has a silicone wrap-around sleeve/shell, which ensures a secure grip even in wet conditions. The box contains a holster, too, and you’ll need to keep an eye on it because it has the USB-C charger port on it, which is required to charge the torch.
The Olight Seeker 4 Pro has an IPX8 waterproof rating and 1.5-meter drop resistance, making it rugged enough for most outdoor activities. Weighing 205 grams with the (non-removable) battery, it’s not the lightest torch out there, but the weight adds to its solid feel.
The torch features a side switch with a rotary dimmer, making adjusting brightness levels on the fly easy. According to the brand, the metal bezel was micro-perforated with lasers, a first in the flashlight industry. I can’t see a functional reason why this is important, but it certainly doesn’t compromise the user experience.
You‘ll find the light output and the battery level indicator lights on either side of the rotary dimmer. It’s a nice touch that you can check the battery level and adjust the light output without turning the torch on. You can also use the dimmer when the torch is on, of course, to change the brightness.
Performance and beam quality
The Seeker 4 Pro’s performance is impressive, thanks to its four high-performance LEDs. The 4,600-lumen Turbo mode provides a stunningly bright beam with a 260-meter throw, making it suitable for search-and-rescue scenarios or lighting up large areas.
For more everyday use, the High, Medium, and Low modes deliver a range of outputs from 1,200 down to 50 lumens.
Controlling the torch is super simple; you just have to depress the dimmer switch, and the light will come on. Double-pressing summons Turbo mode, and triple-pressing activates the Strobe mode.
The rotary dimmer allows you to increase the light output gradually, not just in, let’s say, four steps. This makes finding the correct light intensity easier and conserves battery, as you won’t use a setting stronger than you need. The rotating motion is also intuitive and has a shallow learning curve.
Despite the LED units at the front, the Olight Seeker 4 Pro does generate some heat in brighter lighting modes. I put it on full whack for a few minutes (indoors), and it took only a couple of minutes for the torch to warm up. Due to the silicone sleeve, it also takes a bit longer for it to cool down.
However, the Seeker 4 Pro is more than happy to sustain Low and Medium modes for longer periods of time without overheating. The throw is impressive, even in these modes, so you won’t have to worry about cranking the torch up to maximum and risking system failure.
Battery life and charging
The Olight Seeker 4 Pro runs on a 5,000mAh battery, which offers respectable runtimes: 2.5 minutes at full 4,600 lumens before stepping down to 1,200 lumens for just over two hours, then 600 lumens for another 35 minutes.
Charging is a strong point, thanks to the USB-C-enabled holster. It charges faster than traditional magnetic charging, taking 3.5 hours from zero to 100 per cent.
The torch auto-locks when placed in the holster, which also limits output to 600 lumens—ideal for safety and preventing overheating. I would have liked it if you could charge the torch via a USB-C charger without the holster, but I appreciate that there isn’t an open port on the torch unit itself, which helps durability.
Verdict
The Olight Seeker 4 Pro is a well-rounded, high-performance torch built for those who want power and precision in a portable form factor. Its rugged build, versatile beam, and innovative features make it a top choice for EDC, camping, and professional use.
While cheaper torches with similar lumen outputs are available, the Seeker 4 Pro’s smart features, such as step-less dimming and unique design elements like the laser micro-perforated bezel, make it a premium choice for flashlight enthusiasts.
Also consider
Sofirn SP36: Provides up to 5,000 lumens and stepless dimming through the Anduril interface at a lower price but sacrifices build quality and premium design elements seen in the Olight.
Acebeam E70: Matches the Seeker 4 Pro's 4,600 lumens and features direct USB-C charging, but its user interface is more complex and lacks stepless dimming.
Nitecore MH12S: A budget-friendly, 1,800-lumen torch with USB-C charging for everyday use, though it falls short on output and advanced features like stepless dimming compared to the Seeker 4 Pro.
