The new Nitecore P30i is a serious player. By stacking a large format rechargeable battery and a large reflector, you're looking at 1 kilometer range and 2000 lumens of light.
From the moment you open the well designed packaging you'll see the work thats gone into this grunty work torch.
Nitecore include a remote switch too if you plan to mount it.
Also includes a insert sleeve so you can use 18650 batteries too.
Using USB-C means much faster charging times (Cable included). Have a look around, the 5000 mAh battery is in the top range of capacity and output.
Lets look at the beam profile. The 50mm reflector and its depth work like a speaker cone does for sound. For a hand held torch this size, its outputs are nuts.
