Question: which is better the nite core ea4  860 lumens or the skyray king 6x 4000 lumens  ???
Document: The output of Nitecore's EA4 compares quite favorably with Eagletac's small clicky D series flashlights which pump out 850 lumens on turbo compared with the 860 lumens claimed for the EA4's turbo mode. On turbo mode, the Nitecore EA4's light is more focused. While it isn't a spotlight per se, it does spot better than the aforementioned clicky lights (of which I'm a fan), which have more diffused light output. On turbo, the EA4's output seems a bit brighter than the ten lumen difference in the ratings.
i think this is my favorite nitecore product,a handfull of sun!!! compact,powerful,voltage indicatorand 860 lumens on 4 aa batteries!
This flashlight is actually brighter than Maglite with the same size. Even though these is only 860 lumen the light itself is clearer (clear white) compared to my other flashlight that is actually 980 lumens
I have several LED flash lights.. This is my favorite by far.. 860 Lumens !!! Powered by AA's easy to find.. Fits in really small hands and packs away just about anywhere. Quality that can't be beat..
Its a nice little light. No way its 860 lumens. In my testing, it is good out to about 75 yards and that it. No way does it hit 300 yards like it claims. Someone stole mine and I would not buy another one.
This flashlight amazed me, to be able to insert 4 AA Batteries and produce 860 lumens of pure crisp white light. With a focused beam, you can get a very good range out of the flashlight.The beam of the flashlight is focused and it has a nice large hot spot, with very good throw. The flashlight is lightweight and compact.
Pretty nice light. It&#8217;s very well built and doesn&#8217;t use a carrier for the batteries. Instead the battery slots are milled into the body, a very nice touch. It adds a bit of mass to the light but makes changing the batteries a much simpler task than loading a carrier.It has five brightness levels, 65, 135, 300, 550 and 860 lumens.
I bought this light after I had bought a Fenix LD41. This light is impressive Not only is it about half the size of the Fenix but it is 340 Lumens brighter on turbo (fenix LD41 520 lumens)vs (Nitecore EA4 860 lumens). The switch on the EA4 takes a little getting used to but with a little practice it becomes second nature getting to know the different outputs and how to get to them with either half pushes of the button of fully depressing for an instant turbo mode.
This flashlight is well designed and constructed. The hot spot in the middle of the beam is useful for longer distances the outer beam, which isn't as intense, helps light things up that are closer. This flashlight is good but between this flashlight and the Fenix PD32 Ultimate Edition (740 Lumens). Personally I find myself using the Fenix more, simply because the beam is evenly spread, which helps light things up better.
the real reason for the 4 stars is that low is 60 lumens. quite bright from such a small light. runtime should be better for a low setting. if they had, say 6 lumens or even 18 lumens, the runtime would be considerably better. as it is right now, 22 hours is all you get. the 18 lumens from my TK75's low gives me 260 hours (4x 3400mAh 18650 Protected Orbtronic cells (panasonic NCR18650B cells inside).
