For me I found this light to be a great size for EDC. It’s smaller diameter in comparison to a CR123 light makes it easier to fit into the pocket. This still has the Olight pocket clip which some love and others hate. Personally I like the deep carry ability of it but it does get caught a little when placing back into the pocket. This light can run on 3 different battery chemistries and all have differing levels of performance and run time. Personally I would recommend running this off a rechargeable 14500 lithium based sell. Using this you get the best of both worlds in terms of it’s reliable so costs to operate will be low, and you also have the availability of 600 lumens in turbo mode. On a alkaline or NIHM battery you don’t have the option of turbo mode. Please see my video below for more details.
Overall I really like the light and can recommend it, I really like the fit and finish of this one too.
