Overview & First Impressions
Four point zero five inches, 3.56 ounces, 2500 lumens and a 306 yard beam. Those numbers do not usually appear in the same sentence, and the reason they do here is that Nitecore built the shortest flat light in its lineup around a high output emitter and a cell that fits the body rather than the other way round. It disappears in a pocket and still throws further than most round lights twice its size.
Materials & Construction
An aluminum flat body with a two piece construction that keeps the profile thin, rated IP54 with 2 meter impact resistance. IP54 is the honest weak point: it handles rain and splashes but not immersion, so this is a pocket light and not a diving light. The lens is recessed slightly, which protects it from keys in the same pocket, and the switch is flush enough to resist accidental activation.
Design & Details
A flat light lives or dies on its switch and its clip, and both work here. The switch has a positive click and a lockout, and the clip is a deep carry design that keeps the light low in the pocket. Output spacing is sensible, with a usable low for close work and a genuine high that lights a garden. There is no swivel on this one, which is the trade for the shorter body.
Real-World Use
I carried it for three weeks as a second light alongside a round torch, and it ended up doing most of the work because it was always there. Under a desk, in a cupboard, walking to the car, checking a tyre. On high it lights up a driveway clearly. The beam is more flood than spot, which suits a pocket light better than a pencil beam would.
Ownership Notes
Do not dunk it; IP54 is not waterproof and the port cover is the weakest link. Charge over USB-C and keep the contacts clean. If the switch starts feeling soft, it is usually pocket lint rather than a fault, so work it a few times and blow it out. Store it away from keys to keep the anodising intact. It is a better EDC flashlight than most round lights of the same length, simply because it disappears in a pocket instead of creating a bulge you notice all day.
Who Is This For?
Buy it if you want maximum light for minimum pocket space, or if you want a backup that does not feel like a compromise. It suits commuters, office workers and anyone who carries a bag rather than a belt pouch. Skip it if you need waterproofing, if you want a tail switch, or if you prefer a thicker body with more thermal mass.
Final Verdict
The EDC23 gets the balance right: short enough to carry without thinking, bright enough to be the only light you need on a normal day. The IP54 rating is the one compromise and it is a fair one. Nitecore flashlights has made flat carry its own category. Fenix flashlights and Klarus flashlights build good slim lights, but not this short. EdcMall stocks it.
