Cheers, I actually forgot to mention that this has the nice battery level indicator thing on the side that most of the latest nitecore headlamp releases have. I'm trying hard to find problems with this light in case I am missing something but so far I'm really enjoying it. Usually if I use a headlamp on a hike and completely forget about it or how to use the UI to make changes then its a good one. I have been bouncing up and down trying to jiggle the locking bit out and it wont move so I'm happy about that. My greatest fear on this one was that the beam profile would look like some sort of mess up close on flat surfaces but that's not the case.

I agree I'm usually using Samsung 30Q cells which are 3000mah with a 20amp discharge rate. So this 4000MAH is fantastic. I have 2 lights on my floor here to test and their 18650 cells are only 2600mah! So well done Nitecore for not short changing us. I think you are right on the tint etc. I have some Nichia leds which are beautiful but lose out on efficiency to the other stuff in the same light models. I'm like you i like a warm or neutral depending on what I'm doing. Having said that this 6000k to me looks warmer and my testing was giving me like 5500 level of kelvin.

Thank you very much you know I like a nice headlamp. You have a point with Nitecore, every time I get a nitecore they surprise me and i like their offerings. From the ultralight ones up to these full size types. I was worried the beam profile would look like a right mess with it having so many LED up front but it looks really nice to me so far. What is a bit of a same and not directly related to this light, are the incredible prototype lights they make and give to certain testers to evaluate. Some of them are very impressive and its a shame they don't make it to market but they have to stick to ones which have a wider appeal I guess.

Excellent let me know what you think of it I'm loving this one so far. They have IP68 rating so they are saying that this light can be submerged in water for a period of time however that only rates to a specific depth and for a specific period of time so this cant be used for diving etc. Generally any time I see a flat i think this might let down that rating.

When I read it on the tiny print in the manual I was a bit dubious, however I think what they probably miss out is that on that setting it will run for 2 hours HOWEVER the output will slide down as that runtime goes on. So I don't think its 2000 lumens for the entirety of the 2 hours. Unless I'm wrong of course. The efficiency figures on their website look good for these emitters and I didn't notice any severe stepdown when i was out but its colder here so maybe its a temp based thing.

That's usually how runtime is measured. If you set it in whatever brightness it will simply *stay on* for that amount of time, but usually not at the full brightness for that amount of time outside of maybe the low settings. Edit: Besides, 2000lm is really higher than you need/want for headlamps for most situations in my option. It's blinding for anything up close. Good to have it as an option if you hear something off in the woods, but normal walking only needs a few hundred lumens.

Thank you my good sir. 🙂

Will try and get hold of one for testing. Last time i tired I wasn't able to get one but il try.
