Acebeam X70 - 40000 lm - 8*18650 - Active fan cooling

I’ve publicly offered him the partial refund back too.

All I care about is warning people not to fall for the scam.

It all became too personal and my nationality brought into it.

The other three dozen customers who bought the TA lumen sphere didnt experience the same issues you have. I posted my measurements with the TA sphere and they were in line with ratings from reputable manufacturers whether they are low powered lights or high power lights, flooders and throwers. You were the only one with issues so we tried to help you figure out the reasons but you werent interested in working with us and instead just interested in proving your accusations are right without doing it scientifically.

We are about to recive the Maukka calibration lights so we can verify scientifically how accurate the current calibration of the TA spheres are.

This is off topic, but it’s possible to get accurate measurements with any lumen tube as long as you have a reputable lux meter and
Correct multiplier. The differser sheets are a nice addition to the tube.

The issue was the few cm’s of tube wall before the 1st diffuser, light from heavy flooders would hit those walls and be absorbed. Then there’s the fact the multiple diffusers would take a fixed percentage of light off the total calculated output. Which meant a 1000 lumen light would lose a 100 lumens off the total and a 100 lumen light would lose 10 lumens, unavoidable using heavy diffusing, basically the higher powered the light the greater the overall lumens lost, though at roughly the same percentage, some higher powered lights had a slightly higher percentage due to them being extra floody (side wall) whilst still having high Candela (bounce back), the DX80 lost around 10,000 lumens. Lights with high Candela seemed to be suffering from a possible direct bounce back from the first diffuser.

The only lights that would read correctly would be those similar to what the tube was calibrated with. All my 30+ lights read too low and every light I’ve seen published has read too low.

Basically my 30,000 lumen light is recording 2,000 lux on the Texas_Ace tube then x 10 by the meter for 20,000

My 3,000 lumen light is recording 200 lux and x 10 for 2,000

The tube is not quite calibrated, it would be better x 15 but it’d still penalise heavy flooders, sitting the lights on the diffuser got me a lot closer to Maukka’s results (I have most of the lights he tested and some multiples of the same so I know they are all within a few % of each other) but it would only really boost the flooders.

Oh God, are we really doing this again?! And in another, unrelated thread?! Really KG_Tuning, you need to drop this. Nobody here wants to hear you go on and on about it, the site owner has already warned you and locked one thread over it, and yet here we are again…weeks later. This isn’t a good look man…

Agreed

OMG, you just selectively choose to ignore the data posted to show the TA tube does not favor flooders over throwers. The MT03 super flooder with the same driver and emitters as the throwier MT09R measures about the same lumens, which CLEARLY says your accusation of the TA tube favoring flooders is simply not true for other TA tube users. If you just choose to not read what others post and not willing to work with us to find out the reason for the issues you are claiming, there’s no point of continuing this discussion.

The MS 2010, PowerTac X10000 Destroyer, and Microfire Challenger H5 look really good with alot of potential for emitter swaps. I’m wondering why they weren’t popular and why nobody modded them for more power.

So that X70…

I would imagine their prices where much higher than normal lights and most people just did not see or understand the benefits.

For example, the PowerTac X10000 Destroyer is currently being sold for $700. People probably think the price is too high for only 10k lumen.

Some of the other lights might have reliability issues. Who knows? They may not have been marketed well, either.

If I was a talented modder and I didn’t know the X70 and MF05 is coming out, I would probably buy it at $700 and swap the emitters. Would be amazing to have sustainable 15k-20k lumen output in such a small size.

Fans shouldn’t even an issue when can simply buy a quality fan and design their light around it.

I don’t think any of those fans are small enough. The smallest I saw was 60mm. For a flashlight you need much smaller, like 30mm. I didn’t see that, at least for under $45. I stopped looking after that as the sizes kept going up.

Surely somebody makes IP68 rated fans in smaller sizes, right?

I do spot some 40mm in the $55 range. That’s still pretty big.

Interesting that some people always seem to have all the issues.

Do you mean people or companies?

I think we are just guessing about the issues Acebeam is having.

I’ve always claimed it doesn’t favour flooders because of the Pre-diffused tube sidewalls absorbing spill/flood but people on here can’t be educated and scammers are free to scam.

About the fans, in the german video u can clearly see, it looks 30 or 40mm ? if the final will have those who knows…

What they should also do is some form of oled display or something like imalent or olight to show output etc? if just a button and its gonna glow red when low battery thats kinda weird for a light of this size…

Even with the fans it’ll be quieter than the 3000k Convoy S2+

Has it been confirmed the X70 is getting a boost towards 50,000 lumens?

Hello KG_Tuning, you have made your thoughts on the TA Tube abundantly and redundantly clear. Any further comments by you on this subject will only serve to stir the pot and generate arguments, so please drop the subject in all threads on this forum. Thank you.
