Just recieved the Nitecore P16
My Olight M21 (4 years of service) Warrior is dying slowly. The M21's led is slowly getting dimmer and dimmer. Currently putting out a 100 lumens. So my boss just bought me a Nitecore P16, Nitecore 2600 battery’s and Nitecore i4 charger. I like everything about this light except for a yellow donut and a little bit longer than the M21. These minor things don't bother me much. The P16 is truly an exceptional light. It has good throw, with a decent spill. I use moonlight mode in the morning and night, and the other 2 lower modes for working on servers and pc's, and high mode for up in the ceiling and dark rooms.
I use it almost daily. I am usually up in the ceilings inspecting things and running cable. Sometimes in dark rooms with no power. I use it right before bed and when i wake up (moonlight mode) as to not wake up the Mrs. I also use it when working on the wife’s automobile, you know oil changes, radiator flushes, rebuilding front end, shocks, window doesn’t roll up, heater core (in the dash and a pain in the a$$) swap, power steering pump, spark plugs, Fuel pump, and coil pack swaps.
