If you are looking to purchase a new flashlight, Patriot36 gives extremely thorough reviews, which divulge a plethora of information to consider when making a final decision on a light for you. Perhaps it is not the light he is reviewing, but it gives you things to consider for your individual needs. He also includes comparisons with other lights, so you may see something else you like in a single review. The latest light he is covering is the SRT-3, which is the smallest offering from Nitecore for their Smart Ring Tactical Line.
The SRT-3 flashlight weighs in at just over 2.5 ounces without the battery included. It still pumps out up to 550 Lumens. See all of the ins and outs in the video below.
