Cheers 👍. I do like to try and cover quite a bit so it saves people having to ask follow-up questions after watching. Very happy that you enjoy mate. 😁

For example, NU33 reduces the power to 44% (about 310lm) in 6 minutes.

yes cheers I suspected there may be drop off to get the runtimes stated. I remember seeing this on the older nitecore keychain lights where it basically goes down and down until it flickers out.

Yes cheers for this info.

Oh definitely, no flashaholics and the mass market will lap this up. it looks nice and it works fine. Are there higher capacity lights sure but then they are heavier and if they want to aim this at runners I see what they are trying to offer here. I would like to see this come in at 1000 to 1500 mah model like a NU25 as this is a very small capacity.

its so interesting that you mention this light as I was trying to run with the nu21 and also the nu33. I think the nu21 is border line bright enough but the nu33 is too heavy in comparison for running I was wanting something in between and I feel like the nu25 sounds like thats what it is. Have you got one or are you after one i will see if they have a sale on.

@@TrailTrek Torn between getting the NU25 and 21 :)

True I see some tiny headlamps that suck. I guess they are interested in the ultralight hiking and running scene with this one. First run with this its good at what its intended for, an ultra light weight trail running light. BUT in my humble opinion its borderline as its just enough light to do that but and I will be saying in the full review that it works fine just up to and not into the full technical trail runs level. I cant justify this for use on technical trails with deep roots and loose gravel slopes etc. I'm going to do another trail run test on harder ground with no dampness to darken the mud as well but I feel like I am right on my thinking in regards this suggested usage.

It's right at the limit here due to taking to be mega light weight. I would trail run on turbo if there was no rain and it's was a non technical trail. It's fine for a hike but I'd take a heavier unit with more capacity.

ha ha ha ha ha. cheers yes I thought there must be some kind of drop off to a lower level. My TINI2 only has a 500mah and its just a tiny little keychain light. 360 for 2 hours sounded hard to believe. No Musk miracle going on then I guess.

Nitecores figures must leave out the lowering over time. if I didn't have to work full time I would also do times runtime tests to get a load of graphical data over time for every light. Do you have the testing equipment for this il send you the light are you UK based?

​@@TrailTrekUnfortunately not. I'm from Poland.

@@stefanp5261 ok mate. I work with a lady from Poland and she kindly introduced me to Tłusty czwartek any excuse for me to eat doughnuts is fantastic. 😂🤘

Cheers for the input. If I don't harp on about cri the people that love it harp on at me 😁. I've done a run with this and for me it's at the limit of what I would use to night trail run. And if it was a technical trail with deep roots and so on then I don't think it's enough. I will mention this in the full review. I feel like they need something half way between the NU33 and this NU21. But I guess with this light they are trying to enter the ultra light arena. I love a lot of light on night hikes and night trails. What light do you use on trail?

@@TrailTrek I have a few My no 1 is the fenix 65 rt very good but it is not cheap and the other that i keep as my backup on long runs is a petl swift not cheap again but you get what you pay for great for the brecon beacons
