There’s the Convoy C8+ with a 1mm white flat LED https://www.aliexpress.com/item/1005001973586200.html but as Mr Lightbringer correctly points out, unless we know what you’re looking for it’s going to be tricky to guide you there.
AliExpress defaults to German on my phone as well. Google can auto translate most of it but it is annoying. I have not been able to fix it. Even clicking on the link in the post above takes me straight to German.
I think the 40T (assuming these are genuine Samsung cells) has a much higher amperage rating than the other two, allowing a high-current circuit to produce a bit more peak lumens. With a listed max current output of 8A for the light, I don’t think you would benefit much if at all from a 35A cell, though. So I’d think one of the other, higher-capacity cells would make you happier. However, that’s a guess on my part; others may chime in who know more.
Just want to say thanks for your tip on the Manker MC12 deal! I just ordered one for $34.95 from Manker USA.
Before I read your post I almost bought it on aliexpress for $10 more, shipped from China.
I’ve been wanting to try an NM1 light and I like the size/shape of this. I only hope I can live with the funky UI, too bad it doesn’t have the much better UI of the Manker U22 III (SBT90.2) another interesting model, but I didn’t see that one on Manker Light USA.
