I suspect that % must be Lm in that chart.
Brave to submerge the light!
As I have a lot of 30Q batteries,flat and button top,I decided to buy one without the dedicated Acebeam ones because I saved about €40.00 .Will the K75 work properly with them?
Sorry for late reply, I missed your post.I saw your vote for R90TS in the best of 2019 topic, so I decided to search your posts to see what else we agree on, and there was you question for me. < embarrassed>
Your cells should work ok/fine.
Thank you for your response richbuff. 
What about the switch of the K75?I see that it is spongy and way below the big Imalents’ switch.No clicks.I don’t like it.
It is strange that no one complained about the very short turbo run time in Power mode. After a few seconds, the lumens are reduced to less than half and certainly also the throw. The two Power and Eco modes are misleading. Practically the behavior of their turbo levels is the same! Just look at the reviewer's chart.
Much better is the behavior of the most recent BLF GT-90, with the same LED, whose turbo lasts at least 15 mins. and the performances are even higher than the K75. Look at the video review: https://www.youtube.com/watch?v=xQBDrNKyWKY
Today,I put a new set of Sony high drain batteries,putting the 30Qs already used,in a Astrolux MF04.After that,I checked the beams of the two lights,and I saw that in strobe mode,the MF04 is way better than the K75.For defence I mean.

So Samsung 30Q button tops work good? Or what’s the best alternative to the Acebeam batteries?
Bump.
Which button top cells would be the best?

Hi, I have used Acebeam protected cells from 3100 mAh, they are excellent batteries. The Samsung 30Q (button top) work well.
This would be very interesting. Maybe someone can get a test sample of one…
If I am not mistaken the review is in Thai language. Did he get the K75 from Acebeam free of charge in return for his review? I am asking because I was told Acebeam did not offer the red versions (K30-GT, K65-GT, K75) for review as these are „too expensive“.
Looks so head-heavy that you’d get a wrist workout just looking at it!
Great review, btw.
Great review!
will flat top batteries work with the k75?
i am buying a k75 today and am wondering if I need to pickup button top batteries? I'm using molicel p26a either way (button or flat).
thank you, anyone who can help.
Flat top are too short. Just checked.
crap! Well I'm glad you checked thank you so much. Cause I was thinking they were ok bc the brass buttons in the carrier.
which flat tops dis you check? Not that it matters because they're all pretty much 65mm..
Panasonic NCR18650B MH12210 3400mAh, 65mm. Rattle in the carrier. Very poor contact.
thank you man, I really appreciate it. I would've been livid when I got my k75 in a couple days and didn't have any batteries for it.
