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

Iā€™m just stating my reason of skipping this one. Iā€™m here for budget lights.
I like big lumens and cooling features, but not with this price.
Iā€™m sure there will people calling $750 is a budget light or a steal for this light thoā€¦

Whatā€™s the word on the streets regarding a release day? How pricey are we taking?

Well, MSRP is $750. It will probably sell for a bit less than that as per usual with Acebeam .

I have no idea when it will be released.

I wonder if there will be a group buy?

I am just guessing if they ever had a x70 group buy, it would be around $521.

Price on site is reduced to $649.90. :sunglasses:

Wow, thatā€™s great news! I ordered three of them right away. :stuck_out_tongue:

Sorry to rain on your parade but I already bought the last 6 pieces on stock right before you. Ms. Newman from the Acebeam sales dept. made me such a good priceā€¦I couldnā€˜t resist. :stuck_out_tongue:

sounds like they wanna compete with the x9 soon to be released with that price reduceā€¦ any idea when this is gonna get out?

I hope they use better cells in this battery pack, unlike the X65 which comes with NCRB, ridiculous for a $550 light

what does this mean for a newbie ?

I thinks heā€™s wondering why it doesnā€™t come with the higher capacity NCRGA, rated at 3500mah. I agree, a light at that price should use the best possible cell, considering itā€™s probably less than a $1 more per cell for them.

Itā€™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 :frowning: It would be great if there was 3500mah with 15-20A but u can always dreamā€¦.

Gotcha! I thought maybe with 8 cells the 3500mah GAs might work, but yaā€¦ 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 bestā€¦

@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 8x 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 x 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. Itā€™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 x 21700 over 4 x 26650.

Iā€™m wondering which would be better, 4 x 21700 or 5 x 18650. Would the battery tube diameter be the same?

Lexel was already suggesting to Astrolux to go with a 5 x 18650 battery tube (double length, so 10 cells) for their MF03 to get a sustainable 40k+ lumen output using a buck driver. It doesnā€™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 x 70.2ā€™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.
