It’s definitely not going to use high capacity cells like 3500mah. This light needs high drain cells. Expect nothing higher than 3000mah.

thats a bummer, same as olights x9 but this has way more lumens so the actual runtimes will not be so great Sad It would be great if there was 3500mah with 15-20A but u can always dream….

Gotcha! I thought maybe with 8 cells the 3500mah GAs might work, but ya.. 40,000 lumens is a lot.

I really do wonder since the light is gonna hit 40k lumens why the hell not use 26650 batteries instead? I mean whats the point using 18650 if the highest capacity on each cell is 3000mah? thats way too low yes, even for the olight x9 which is rated for 25k lumens is low, i dont get it the lights are big as a house yet they use tiny 18650 packed together producing a meh runtime at best…

@JasonWW u that know so much can u chip in and help me out understand their logic doing this ??

The tube will be so huge with 8× 26650. I would much rather they use 21700, which have about the same capacity as the 26650 and allow higher currents. Does anyone know how they are configured series/parallel?

The 26650 is not as efficient as a 18650, 20700 or 21700 because they are not made by any of the big 4 Japanese battery companies who have special chemical mixes developed.

So the 26650 power density is not very good. The package size is double the 18650, but output is not double.

Two 18650 gives you a 20% boost in runtime compared to a single 26650 even though they have the same internal amount of space.

These smaller battery companies do seem to be slowly catching up, though.

Plus 8 × 26650 is way too big to hold. You would need a handle.

A good compromise might be using four of the 21700 sized batteries. These are still pretty new so flashlight companies might be taking a conservative approach to using them. It’s internal volume is about 50% bigger than an 18650, but output is not quite 50% higher.

Check out this comparison between the Samsung 30Q and the Liitokala Lii-40A. Both are rated at 15A continous discharge.

Now the good ol Liitokala 26650 is good for 20A continuous, but if the X70 is shooting for 15A continuous per cell then performance is very close to the smaller Liitokala 21700 Lii-40A.

This would be the smart move in my mind. 4 × 21700 over 4 × 26650.

I’m wondering which would be better, 4 × 21700 or 5 × 18650. Would the battery tube diameter be the same?

Lexel was already suggesting to Astrolux to go with a 5 × 18650 battery tube (double length, so 10 cells) for their MF03 to get a sustainable 40k+ lumen output using a buck driver. It doesn’t have the cooling to handle it, but the driver can really do it.

I agree.

How the batteries are wired depends on their driver design which they are not telling right now.

Water proof to 2M is hard to accomplish, cooling 12 × 70.2’s ? We will see when someone test it. But still a Game Changer. Maybe your last light to buy. I will buy one after winning the lottery later this week.

Why do you think this? Good seals are all you need.

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 !! Facepalm

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

Fan do make miracles. Big Smile

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 street price on the X70 will be around $499 when the dust settles.

As Jason noted, the fans will make a huge difference. The ability to throw down 20-30k lumens of continuous light is going to be a game changer.

And the overall quality and reliability of the DX80 is quite poor [even for a consumer grade light]. Whereas the X65/X70 are [real deal] military grade lights made for folks who rely on their gear to earn a paycheck.

Comparing the DX80 to the X70 is apples to watermelons.

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 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?
