100 lumen, 2,000 candela with 1 hour runtime.
The streamlight TLR7-SUB is another great option, and you get quite a bit more performance with
500 lumen and 5,000 candela, and 1.5 hours of runtime, more candela is always a good thing even more then lumens, candela will give you farther throw and greater light barrier penetration. Like if your driving down the road and you have your low beam on and someone is driving towards you with super bright high beams on, you can't see because their bright have more candela, candela is what let's you see past an opponents flash light or spot someone hiding behind a light pole.
Vuds has the P365 compatible TLR7-SUB in stock here
