The three brands people cross-shop are Nitecore, Fenix and Olight, and they have distinct personalities. Nitecore chases maximum output. Fenix builds the widest, most conventional line with the toughest bodies. Olight makes the smallest and cleverest lights with magnetic charging. This guide compares them on the things that decide a purchase and tells you which to buy for what.
Output
Nitecore wins. The EDC29 at 6500 lumens and EDC37 at 8000 are in a different class from Fenix's 3000-lumen 21700 lights and Olight's 1600-lumen Baton. Nitecore manages it with thermal sensing and dual-stage buttons.
Range of models
Fenix wins. Pocket lights, tactical, duty, headlamps for three different jobs, lanterns, UV and laser lights. If there is a category, Fenix has a light in it.
Size and cleverness
Olight wins. The Baton 4 Pro is the best small light on the market and the ArkPro packs four emitters into a flat body. Magnetic charging is a convenience nobody else matches.
Batteries
Fenix uses standard 18650 and 21700 cells with USB-C, sometimes on the cell and sometimes in the light. Olight uses proprietary magnetic pucks plus, on newer lights, USB-C. Nitecore's EDC series has built-in cells with USB-C.
Durability
Fenix, by reputation and by IP68 ratings across the line. All three are well built.
Which to buy
One light, no fuss: Fenix E35R. Maximum brightness in a pocket: Nitecore EDC29. Smallest and smartest: Olight Baton 4 Pro or ArkPro.
