Nice review!
A constant frequency Strobe accessible by the tail switch would be nice.

Thanks for the review. But, are those duv numbers correct? I don’t recall seeing numbers that high anywhere else on the SFT25R.
I’m not too surprised, the SFT25R in Wurkkos TS10 SG also measured a comparable level of green. And the green does show up very well in the review photos.
This is a HI version, maybe other numbers were from the HD version? The numbers are absolutely correct and my testing always closely correlates with other reviewers testing.
The green in the profile beamshot was even more green in the original photo taken (auto white balance) and I had to give it +16 magenta shift in Lightroom to match what my eyes were seeing. I think the vast majority of non-flashlight enthusiast buyers would however not be concerned with the CRI and tint, but flashlight enthusiasts will question it. Tint is also less of an issue if there are no other light sources around as our eyes/brain auto white balance, but as soon as you are near other light sources, then +ve DUVs are noticeable.
The throw is very impressive though!

From your review, I tested the step-down with a thermal camera on my blue sft-25r. An Acebeam CS reprensative told be via Aliexpress messenger that the step-down is thermally controlled and should step down at “about 55℃”.
After 3 minutes 45 seconds the light head reached 58℃ and step-down occured after 5 minutes when the head reached 61.8℃. This is very toasty.

Thanks. Sounds like your testing has validated my more crude testing, and that I was right to publish my review as the issue will be occurring in multiple lights. This issue caused the Acebeam rep to be abusive (more detail on Reddit), to the point that I will now refuse to review their lights.

Acebeam advertises that this light holds 800 lumens for 3 hours. This sounds like a big lie to me.
But why is Acebeam doing this??? One of the few brands I used to trust.
Probably just a mistake…

They dropped the ball on this one, but don’t want to admit it.
They may have meant 80lm for three hours.
It sells.
If you look at those graph it is done “by the book”, as deceptively as possible with varying scale to visually improve how things look etc.
Just look at how the graphs in marketing material visually compare to actual runtime testing…

That graph makes me want to stab someone. Specifically, the person who made it, or the person who approved it to be part of the marketing. Deceptive as hell, and it doesn’t even need to be. Acebeam generally makes good products.
Looks like they removed that graph. Wow, it was fast!
