No PWM on low mode which makes this a high quality flashlight. Output always starts in high mode after waiting a few seconds after turning the flashlight off. You can avoid strobe & S.O.S. mode just by turning off the flashlight in high, med, or low mode and waiting a few seconds before turning the flashlight back on. Machining and anodizing leaves a good first impression. Flashlight includes a red diffusing cone that screws either on the top or bottom of the flashlight. Flashlight can tail stand both without the cone screwed on or not. Tail standing is rock solid. Beam tint is white with no green or blue hue. You can find artifacts in the beam pattern when pointing the beam at a light colored wall but hey it is a flashlight. I can not speak about how long the battery will last because I just received the flashlight today 09/03/2020 . Flashlight can only use regular AA type batteries. Alkaline, Nickle metal hydride 1.2 volt Eneloops, or primary lithium 1.7 volt Energizer batteries. No rechargeable 14500 batteries. Emitter is well centered in the reflector. I would recommend buying this flashlight.
