Based on the battery pack there appears to be a 3rd version now too, or maybe it was just a minor change in the production run.
I would figure search and rescue. A bright light that can continuously output really bright light is better than a bright light that can’t, may as well pave the way for bright lights with endurance.
What I think would be ultimately awesome is a bright flashlight that also has a power input connector to hook up to a battery bank. These flashlights that have tripod mounts are only useful until the battery runs dead. A bright light with a tripod mount, active cooling, and optional external battery bank hookup for continuous operation could seriously be handy.
I agree, but it does kill all the other lights when it comes to the combination of lumens + throw for as long as possible without stepping down. It also allows you too see further because there is no spill.
Changes to the design I would like:
- Replace the weird lens above the LED with a classic pre-collimator (spherical lens) to get a normal looking hotspot
- Enlargen the battery compartment for 26650s and 21700s
- Make it waterproof
- Replace the “stick” switch with a more robust looking one and replace the metal swetch guard with something more elegant
I do wonder though if their lights are really that much better or if they are just daring anough to offer the longer warranty. The flashy, “high-quality” packaging is certainly part of the higher price.
Thanks for the feedback, while there aren’t any plans for a storm replacement in progress I think some future lights probably will focus more on beam quality even if there is some sacrifice in performance (I get a little obsessed with maximum performance sometimes :smiling_imp: ). The later built ones actually do support 21700s but it’s not advertised because it’s not all of them (I think there is one 20700 still in stock). Yes future lights will have better water resistance, although it can be tricky in these unconventional designs due to the added complexity that must be balanced against the ability to produce them in house on such a small scale. I do love the toggle switches, they have such a nice feeling to them, tried to do a full sized one but they take up a ton of space and it’s nearly impossible to find one in the very odd configuration needed, also very hard to find nice guards for the smaller toggles. Still this size toggle is pretty durable.
Nope, not yet. That’s the same old page with no info on it from over a month ago. It’s also the same link I have in post #1.
I bet the X70 is going to be $700+
Possibly. The PowerTac is $720. It’s only 10k lumen, but made in USA.
Acebeam is made in China so that lowers the cost, but it’s also way more powerful. So I’m thinking at least $600 to $800. If it works well, it will probably sell well.
If the fan doesn't drain the battery too quickly, I'm sure they are going to do really well.
A tiny cooling fan draws a fraction of what an LED draws. So combined with many high current leds, the fan is not even going to be noticable to the batteries.
It should be interesting then what Acebeam and Astrolux have for us. I hope it's not going to be a gimmick such as a high lumens light with several mini fans and 1 minute longer run times on max than lights without cooling.
@50 seconds
Thanks.
Wow, the X70 is rated at 40,000 lumen. Looks like 3 small fans.
Did they mention the price?
Acebeams X70 Web page has been updated. I added that data to post #1.
I have to admit, it's an impressive looking light. German guy in the video says the three fans are waterproof, and that the fans would not work if submerged in water but that there shouldn't be any damage if that happens. I like the shoulder strap. He also showed the paper that read 30 minute run time, but I wonder if that means 30 minutes at 40,000 lumens or not. Not clear enough yet.
Sustained 40k lumens doesn’t sound possible, does it? The PowerTac 10k seems to cycle it’s single fan. So if the X70 has an efficient heatsink design with each fan cooling 1/3 of the heatsink area, the fans run continuously and power output drops with battery voltage, then maybe it is possible.
40k lumen for 30 minutes is quite a record. Even if output starts to slowly decline. I have no idea what driver design they might be using.
40,000 ÷ 12 = 3,333 lumen per emitter. That’s roughly 3.5A 4.5A per emitter. 42 54 amps at the 6 volt level or 21 27 amps at the 12 volt level.
21 27 amps at 13 to 14 actual volts would be 273 to 294 351 to 378 watts.
As far as the batteries, it’s using 8 x 18650. If the cells were 4S2P (like the Imalent DX80) that would require at least 10.5A 13.5A per cell. Good cells like 30Q should handle that amperage and temperature it seems (internal battery temp due to the heavy discharge, not heat from the head).
So maybe it is possible. I was not expecting 3 fans. That could be the key to maintaining the high output. Even if your down to 30k lumen when the LVP kicks in at 30 minutes it’s still a remarkable feat.
It really doesn't sound possible. Perhaps that is why the sheet the guy displayed on the video was very vague with no real details. It has to be 30 minutes with a step down I would think, but if it was 40k lumens at 10 minutes and 20 minutes at 20k, even that would still be a huge break through. It would make the Imalent DX80 already seem obsolete by a long shot. You can see they put a lot of thought into the X70. I noticed the reflector is screwed down nicely and the battery charge port is threaded with an o-ring and end cap. Much better than a rubber flap.
MicroFire L500R V3 NW - YouTube should add microfire lights to this list.
Microfire Challenger H5
and
Microfire L500R V3
I will look into those.
Just an update. Acebeam has announced the list price on their X70. It is $750.
I was asked about the triple fan power consumption of the X70 in another thread, so I figured I’d post it here, too.
No one actually knows the size of the fans in the X70, so judging by the video I guess they are about 40mm. The typical 40mm fan uses about 1.2 Watts of power, so three of them would be 3.6 Watts. Compare that to the 350+ watts the emitters are drawing on Turbo and the fans are only using about 1% which is not significant at all. I’d say it’s negligible.
