Unhappy customer I sold mine. Cheersssss
Both ChibiM and ZeroAir have tested the 4000k warm white version, which is specced at 38,000 lumens. They both got about 35,000 lumens at turn on and about 30,000 lumens at 30s.
(I’d like to point out that whilst this is under the specs, 30,000 lumens from something this size still seems incredible to me.)
Anyone measured the cool white one that’s specced at 40,000 lumens?
ZeroAir have tested the XHP70.2 (not XHP50.2 as it says) 5000K version.
Stepdown from 35.000lm to 30.000 is right for a flashlight of this size.
The only issue is that acebeam doesn’t admit that cd/m measurements are not correct. Nobody (except the Chinese review which I think is very optimistic) has achieved the advertised meters. For everything else, this flashlight is amazing!
does it matter when your light fails to meet stated specs? it should be accurate and not that much lower, that to me is not good for a light this price range.
Yes indeed. True what you saying.

Acebeam X50 is UNIQUE !! We do never compare other brands. We have been working hard and serious-minded for making great products.
This is my opinion, but Acebeam X45 is better choice!
Yes, I do agree with you. However X45 was discontinued, and X70 is discontinued too.
We have been working hard to make more excellent products continously.
Average reading on my CW is around 630 meter distance.
But if you agree with the above opinion, this logically leads to the conclusion, that you downgraded the product this time for exactly double price. Or it was a typo?
Because FOURTY THOUSANDS LUMENS!
That’s what people want right?
Thanks for fans sharing us with their X50 !
I came here because I was very interested in this light. Unfortunately, the proprietary, built-in, battery pack is a deal breaker for me. I’ve been serious in this hobby for 20 years and I have a collection of flashlight “paperweights” with built in, or proprietary battery packs, that no longer work… and the packs can’t be replaced. I’ve learned my lesson.
If this were a 4 x 21700, user replaceable battery pack/tube, I’d purchase one.
I’d also like to see an option for a smooth reflector, as the ones in the pictures seem to be heavily orange-peeled, which greatly smooths the beam of course, but doesn’t help in the throw department.
Lastly, I’d like to see a SBT-90 variant. Yes, I know it would be more expensive but it would also easily meet and exceed the 800m throw claim, which it certainly doesn’t do now, based on the several different reports I’ve read. Based on the current formula, I didn’t really expect it to.
Oh well, perhaps in the future…
SFN55.2 is like a domeless XHP70.2. Would be great for increasing throw.
Sounds interesting.
Perhaps fewer lumens without the dome, I’m guessing? I would imagine Cree accounted for tint shifts without the dome on the SFN55.2.
Domeless XHP70.2 is much better. If any guys are interested in, please send email to pre-order the customized domeless XHP70.2 X50. sales@acebeam.com
That neat. Do you have specifications for this one?
I got mine today. It compares favorably with the X45. More lumens in the form of a wider beam, both of which are provided by more emitters in a smaller head diameter with smaller reflector wells with more overlap. I selected 5000K neutral white. Nice tint, and oodles of very wide, extremely bright flood. Flood is this lights' primary forte; the amount of throw that it has is by sheer dint of the eight powerful emitters. Therefore, it has a massive amount of the former, and the expected amount of the latter, which is sufficient for its designed purpose.
For longer run time and less heat generation, lower modes can be selected.
I started out as a flood guy, and only later got into dedicated throwers, such as K70 and K75; and to power throwers, such as X65. This light very much and very happily satisfies my primal, deep seated flood urges. Also, the X50 is tops at brightly illuminating the widest area, for its size classification. Not too big, and not too small. I think that the X50 is currently the most powerful light in its size class, which also happens to be a very useful size classification.
