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

Acebeam X70 40K Lm $650 on the official site
Imalent DX80 32K Lm $250 (ledsupermall.com)
Difference $400 !!
Difference is 8000Lm. Barely noticeable.
In addition, X70 will be noising with three fans.
Acebeam did not still write the the length of time of the high levels before the stepdown to 4000Lm. Fans do not make miracles with 40k. Maybe you spend $ 650 for 1-2 minutes of turbo !! :person_facepalming:

It is not the K70, that is a different model. This is the X70.

Fan do make miracles. :smiley:

DX80 can only do 7k lumen continous.

With good cooling 20k continous should be easy. We don’t know the limits of X70. It might can do 30k lumen or more continous. It will definitely blow away the DX80 in continous output.

The X70 is not a general purpose light. It is built for a very specific job where you need high continous output such as search and rescue, police, emergency services, etc… This light will not be so practical for the average person due to the price.

The DX80 is more a general purpose light. If 7k lumen continous is all you need, then the DX80 is the light for you. It’s much cheaper which makes it practical for more people to own.

The only reason flashlights have fins is because they rely on air displacement to cool. And displacing air is exactly what a fan do, it’s not a miracle, just physics.

The DX80 was an attempt to win the lumen war and for a while it did, however its engineering was very poor and they clearly did not design it with reliability in mind, in the other hand Acebeam is one of the few brands to exceed CREE maximum rated drive current, they are expensive but when it comes to build quality and driver design, there’s not much around that can compete. So yeah it’s a bit unfair to compare the two.

Im still curious what runtimes they will manage to pull off on the x70, i have the X9R which is a fantastic light but once it drops to like 50% battery or lower the max output is only at the third highest lumens, (6400), i guess its a limit of the low volt on the batteries so i asume similar will be on the x70 ? there is a reason they havent posted the spec sheet for all the runtimes etc….

My guess is total runtime 60min max….

I disagree with this. They used a badly designed driver in the EC50 II. The diode gets more current than it’s specified for which can lead to premature failure. There are also Bugs in the U.I. Their lights don’t have real PID thermal regulation even though some of them are redicouisly powerful for their size and get too hot to hold very quickly (again the EC50 II).

The build quality is standard fare, nothing special. There are many manufacturets offering this kind of quality. Of course there are always ones with worse quality…

I paid $216.95 with code for DX80 only!

I just recieved information that the light may be released in the next 2 months. This is my response to a question about preorder.
“Hi, Mr Patrick, X70 is currently in the process of being improved and could go on sale after at least two months. I suggest you try our new X80 series like X80-GT”

2 more months? Bummer. I thought it was ready to go any day now.

Some of those new X80 versions are crazy. Who needs all that massive UV light?

I guess you can use it for disinfection/sterilization over a large area. Kill bed bugs maybe?

wow still, i think they try to improve the battery or performance of the light then now that the x9r is out then relate to the runtimes on that and that their light will do almost 15000 more lumens so they better do a good runtime because who wants a light for that price if its not even 1 hourmax?

2 months… I think that’s wishful thinking… they are obviously struggling with the fans… Eg… just like the X9R they eventually ditched the fan…

Yes, but it’s also the most likely explanation. Especially considering the fans are the most complicated part to get working reliably.

My next most likely guess would be due to the high output. 40k lumen is a lot of power. The DX80 had to go through several revisions.

On another note…

Last week he told me Acebeam will no longer be making upgrades to the X65. They are instead concentrating their efforts on the X70.

My EC50 Gen II is one of my favorite lights. Been using it often over the last year. UI is great, build quality very good. Considerably better than the average chinese flashlight. Also have the EC35 which is very good too.

What upgrades did they make for the X65?

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 ?
