Size: fits well in a jacket pocket, you can put it easily in a pants pocket, but it’s not going to be comfortable there unless they are cargo pants.
Overall fit, finish, and feel: Like other Olight products, the Seeker 2 Pro gives you a premium feel with the blue anodizing around the bezel and shallow crenellation giving more of a high tech and functional impression rather than tactical. One defect to note – there was an obvious anodizing defect next to the bezel.
Light output: I was a little surprised that despite the move from a single Cree XHP70 to 3 Cree XP-L HD cool white emitters, that the max light output rating was unchanged, particularly since these emitters are super efficient (200 lumens per watt, based on the CREE specifications!!) However, when I tested the light in my basement "bounce chamber" the flashlight appears to put out well over the claimed 3200 lumens on turbo, perhaps closer to 4300 or 4500 lumens when on a fresh charge, though the power does taper fairly quickly. The other settings were within the right ranges, with the 300 lumen setting potentially being on the low side.
Beam pattern: Fairly floody pattern, though when you have 3200+ lumens, you can pretty much see everything out to 40-50 meters and more.
Battery: instead of the 26650 of the prior-gen Seeker, the Seeker 2 Pro uses the 21700 battery which is smaller but has 5000 mAh instead of 4500. The 21700 was developed by Panasonic and Tesla to be the most space efficient. In this case the light claims 9.5 hours at 300 lumens, quite a long time for that power level, while it also is able to put out 1200 lumens for 110 minutes, also impressive.
Features: Standard set of Olight features with the magnetic rear charger, moonlight mode, lockout, low-med-high and double click for turbo. There’s also a L-bracket for mounting the light to a desk, closet, etc – specifically not a vehicle though –braking or hitting a pothole and the light is likely fallen. The new features which are nice are the tacky rubber grip, and the light / battery status LEDs. The holster is also fairly standard for Olight with a buckle rather than Velcro.
At first you might wonder “do I really need an indicator light to tell me what light setting I’m on?” but after you’ve had it, you find it’s very useful. I often find myself cycling through the settings to see which setting I’m on, and of course this changes that. Overall, nice added features.
