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

While comparing a friends older X65 to ours (from the latest run), we noticed some differences. This sparked an interest to see what other changes
were made that weren’t easily visible. This list was complied from a series of emails over a period of 2-3 weeks with both Acebeam and my dealer.

- Battery indicator light was moved from the switch to a stand alone indicator light forward of the switch.

- Improved switch. Earlier switches were soft with little feedback. The latest switches are firm and positive.

- Updated reflector design for improved beam quality and less artifacts.

- Updated battery pack. The newest battery packs have been improved for better performance.

- The screws inside the head used to be Phillips. They are now Tamper-pruf screws.

- Improved UI. The double click timing to access Turbo and Turbo Max has been updated.

- Improved tailcap to ensure the lanyard ring rotates freely after a drop or impact.

- Improved centering ring to ensure the LED’s are perfectly centered at the factory.

- Improved anodizing.

Nice thanks for the useful summary! Seems pretty significant.

And how can we know if a X65 is one of the new or from older deliveries? Can we ask for the Serial number?But which is the first S/N of the new deliveries?

It didn’t happen all at once, but instead was a series of small changes and upgrades over the course of its production.

I asked that question and the answer was to simply ask the dealer if their supply is recent from Acebeam.

I think its more struggling how get decent battery life from 8 x 18650 batteries thats gonna power 40k lumens and 3 fans also… thats the problem i think. Not the fans alone why would those be a problem ?

The fans need to be water proof, rust proof, dust proof, etc… for 5 years (that’s Acebeam’s usual warranty period). Maybe in their testing the fans can’t last more than a couple years.

We saw where Olight designed the X9 fan to be in a removable cartridge for easy cleaning and replacement.

Maybe Acebeam is having issues with that? Who knows. :slight_smile:

If you think about how many electronics are using fans I’m wondering if that’s really a problem.

Really? Name one electronic device using fans that also goes under water?

That sounds ominous. I hope they are not giving up on the fan cooling like Olight did.

Hopefully they get it all resolved! I have my wallet ready!

I really hate how the more I see this thing the more I want it. 40,000 lumens with a 1km throw is just hilarious and absurd and I love it.

Edit: Still not in love with the price though. But that’s retail MSRP.

Interesting, I assume the first batch originally used Panasonic NCR-B, what cells are they using on the upgraded version?

Fujitsu is at least several thousand times the size of Acebeam and Olight. They have a huge amount of resources and thousands of engineers to perform research and development for products that sell in the millions. In comparison, Acebeam probably has a handful of engineers that develop products that sell in the hundreds or maybe thousands. For a company the size of Fujitsu to develop this capability is an achievement worth noting but for a company like Acebeam to successfully develop this feature is remarkably impressive.

I just hope Acebeam don’t end up failing like Olight. Would be funny if a bargain brand like Astrolux end up as the only one that can make an actively cooled flashlight.

I think most of the problem Acebeam is encountering have to do with making the fan water resistant, but they don’t have to if they used a separated motor and propeller assembly with a waterproof bearing in the shaft. Motor remains isolated and dry in the driver bay.

They’re probably limiting themselves by using regular computer fans where the motor and controller is inside the propeller, this makes the whole assembly exposed the elements.

Yes, that qualifies. One tablet that was released in 2013 and seemingly only sold in Asia. So not many devices at all.

I think that proves it’s definitely a problem.

What do mean? There are/were several active cooled lights on the market. More info on them here.

I think only 2 are still being sold.

I suggest to any manufacturer with a fan-cooled light to just do away with the ‘Waterproof’ guarantee and start selling.

I myself do not want a ‘lighted, bright torpedo’ … :beer:

Im still curious how good or bad the battery life on total runtime will be, it cant be very high if its gonna use 8x18650 batteries 3000mah… Compared to whats out there they cant really do magic…

oh wow someone fears the astrolux mf03 a little it seems :wink:

Hopefully they resort back to the control ring! Lol
