Yeah it might be rated 1000 lumens but I guarantee it would be far far less
The Nitecore will definitely be the brighter light but as mentioned the distance the centrre spot throws will be greater on the C8 due to the reflector being bigger and deeper.
I received my nitecore EA41 today, but I couldn't really have it, as its a xmas present, but I did have a play about with it for a few mins, to check it worked properly, wasnt damage, ect.
I didnt really look at it too much, just a switch on and go though the modes. It seems like a much whiter light then my C8, as the C8 had a blue tint. Also to my amazement it remembered "turbo" mode, so if I turned it off in "turbo" it would come back on that mode. I was expecting it to come back on to "high" mode not "turbo"
I would say its deffo brighter then my C8 on turbo mode and as bright in high mode. I haven't used the C8 in a few months now, so not 100% sure about that. But the real test will be outside, as then I should be able to tell if it shines better then my C8 did, but will have to wait for xmas night for that
But with the little time I have had with it, it seems good, I haven't looked at the reflector straight on, but what I have seen of it its very shiny and clean. I wouldn't want to look at the reflector when its on in high or turbo mode though.
