EdisonBright Fenix TK16 V2.0 3100 Lumen LED Tactical Flashlight with 2 Rechargeable 5000mAh Li-ion Batteries & Holster - High-Power Outdoor Flashlight for Camping, Hiking, Emergency, and Tactical Use

Let's start with that 3100 lumen turbo setting. Informal testing tells me that number is legit. My Streamlight HL 5-X is known to put out around 3200 lumens in real world testing and direct comparison shows the much smaller TK 16 is very nearly as bright on turbo. Throw is very very close as well. Spill angle is a bit narrower on the TK 16 but spill light quality is excellent. After 60 - 90 seconds on turbo the light steps down power to reduce heat but that's unavoidable with this much light in this small of a package. Even with the light "only" set to1000 lumen there's enough light to handle just about anything. With the five light levels on this light you could do anything from reading a book next to a sleeping partner on eco, to lighting up acres of land at once or lightning up an animal at a thousand feet using the turbo setting.Beam color is a very cool, bright white.Battery life is Ok but that's what spare batteries are for anyway. Get the Fenix two cell charger if you don't already have a charger. Yes it will charge these longer than normal batteries. This light will run for more than two days on eco mode, great for emergency use.Build quality is outstanding. This is a professional quality light. The two switch layout is genius and very intuitive. The TK 16 is still small enough to wear on a duty belt.The only slight negative is the lack of charging port / the need to remove the battery to charge. For a professional user who may need to do many battery changes a week this could be an inconvenience. However, this eliminates a potential point of water intrusion. It's very common for rechargeable lights to have a rubber port cap that no longer seats correctly after a while and once that happens water can take a toll. The TK 16 will never have that weakness. So personally I'm fine with the lack of external charging port, but some won't be and this is worth noting. It's also a bit of a shame that no charge indicator light was included but this isn't a big negative as the light continually steps down over time and eventually flashes periodically so you get plenty of warning. I would have preferred a flatter black finish but now I'm really nitpicking.This is an outstanding and highly versatile light, and it's well worth the money.
