This is off topic, but it’s possible to get accurate measurements with any lumen tube as long as you have a reputable lux meter and Correct multiplier. The differser sheets are a nice addition to the tube.

The issue was the few cm’s of tube wall before the 1st diffuser, light from heavy flooders would hit those walls and be absorbed. Then there’s the fact the multiple diffusers would take a fixed percentage of light off the total calculated output. Which meant a 1000 lumen light would lose a 100 lumens off the total and a 100 lumen light would lose 10 lumens, unavoidable using heavy diffusing, basically the higher powered the light the greater the overall lumens lost, though at roughly the same percentage, some higher powered lights had a slightly higher percentage due to them being extra floody (side wall) whilst still having high Candela (bounce back), the DX80 lost around 10,000 lumens. Lights with high Candela seemed to be suffering from a possible direct bounce back from the first diffuser.

The only lights that would read correctly would be those similar to what the tube was calibrated with. All my 30+ lights read too low and every light I’ve seen published has read too low.

Basically my 30,000 lumen light is recording 2,000 lux on the Texas_Ace tube then x 10 by the meter for 20,000

My 3,000 lumen light is recording 200 lux and x 10 for 2,000

The tube is not quite calibrated, it would be better x 15 but it’d still penalise heavy flooders, sitting the lights on the diffuser got me a lot closer to Maukka’s results (I have most of the lights he tested and some multiples of the same so I know they are all within a few % of each other) but it would only really boost the flooders.

Oh God, are we really doing this again?! And in another, unrelated thread?! Really KG_Tuning, you need to drop this. Nobody here wants to hear you go on and on about it, the site owner has already warned you and locked one thread over it, and yet here we are again…weeks later. This isn’t a good look man…

OMG, you just selectively choose to ignore the data posted to show the TA tube does not favor flooders over throwers. The MT03 super flooder with the same driver and emitters as the throwier MT09R measures about the same lumens, which CLEARLY says your accusation of the TA tube favoring flooders is simply not true for other TA tube users. If you just choose to not read what others post and not willing to work with us to find out the reason for the issues you are claiming, there’s no point of continuing this discussion.

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.

The MS 2010, PowerTac X10000 Destroyer, and Microfire Challenger H5 look really good with alot of potential for emitter swaps. I’m wondering why they weren’t popular and why nobody modded them for more power.

I would imagine their prices where much higher than normal lights and most people just did not see or understand the benefits.

For example, the PowerTac X10000 Destroyer is currently being sold for $700. People probably think the price is too high for only 10k lumen.

Some of the other lights might have reliability issues. Who knows? They may not have been marketed well, either.

If I was a talented modder and I didn’t know the X70 and MF05 is coming out, I would probably buy it at $700 and swap the emitters. Would be amazing to have sustainable 15k-20k lumen output in such a small size.

Fans shouldn’t even an issue when can simply buy a quality fan and design their light around it.

The low mode should be lower.

I don’t think any of those fans are small enough. The smallest I saw was 60mm. For a flashlight you need much smaller, like 30mm. I didn’t see that, at least for under $45. I stopped looking after that as the sizes kept going up.

Surely somebody makes IP68 rated fans in smaller sizes, right?

I do spot some 40mm in the $55 range. That’s still pretty big.

I think we are just guessing about the issues Acebeam is having.

I’ve always claimed it doesn’t favour flooders because of the Pre-diffused tube sidewalls absorbing spill/flood but people on here can’t be educated and scammers are free to scam.

About the fans, in the german video u can clearly see, it looks 30 or 40mm ? if the final will have those who knows…

What they should also do is some form of oled display or something like imalent or olight to show output etc? if just a button and its gonna glow red when low battery thats kinda weird for a light of this size..

Even with the fans it’ll be quieter than the 3000k Convoy S2+

Has it been confirmed the X70 is getting a boost towards 50,000 lumens?

Hello KG_Tuning, you have made your thoughts on the TA Tube abundantly and redundantly clear. Any further comments by you on this subject will only serve to stir the pot and generate arguments, so please drop the subject in all threads on this forum. Thank you.

If the same driver and emitters used in a super wide flood host and a thrower host results in about the same lumens measured in the TA tube, that clearly shows the TA tube doesn’t favor flooders or throwers. Really how difficult is that to understand????? If you refuse to use reason and logic, there is no way we can help you get to the bottom of your issues.

Sorry sb56637, I was trying to give a few facts to help KG clear his misunderstanding of the TA tube but now realizes it is futile. I won’t continue this discussion further.

I just realized this light isn’t going to be like a brighter X65. I was hoping for a high lumen thrower like, “And f••• that guy in particular waaaay over there.” But looking at the reflectors it’s going to be more like an Emisar D1S is trying to escape getting eaten by an X80.

Still excited but maybe not the instabuy I thought it was going to be.

None of these 20k lumen and up lights are really throwers. You need to have a certain emitter die size to reflector size ratio for good throw.

Now if each 70.2 had a 2.5”-3” reflector, then you’d get some pretty good throw, but the head size would be huge! Big Smile

I was going through the throwers on parametrek when I realized the X65 had more throw than the X70 and I thought, “Wait wait wait. What?” And that’s when I finally looked at the head of the X70 and realized just how monstrous an X70 would have to be if each LED had a reflector like the X65 does. It would have to be vehicle roof mounted!

Imagine an X65 with the head size of a 4Sevens XM18.

It would have 12 slightly bigger reflectors, instead of the 18 smaller ones you see in the pic.

Where do I write the check out to? (Just kidding my wife would kill me.)

Edit: would be a great recommendation for all the people asking for a “self defense flashlight.” “Buy this thing, it’s a medieval mace with +3 fire damage.”

Isnt lights like this meant to just shoot tons of light like crazy vs throw very long? not really like throwers even tho this one is gonna go for like 1km it still impressive but u wont get that tight beam tho. Also u can take a swing at someone in case self defense would be needed lol.. Im curious how the final version will be like and if they ditched the fans it means they had same issues olight had..

It sounds as if they won’t be using fans, but have found a different cooling option.

Possible radiator and coolant?

Wrong way, they want to make it simpler, not more complicated. BTW, it would still need fans for the radiator.

What other ways are there to actively cool besides using fans?
I hope they dont do passive cooling :/

If neither acebeam or olight can manage to produce lights with active cooling then it seems something is wrong no? because waterproof fans etc exist so i dont get it ?

I doubt they can go fanless, even the x9r if i run for almost 3m it gets quite hot at the head, so that much more lumens is almost worthless if they go full passive since that light will produce more then what 220W of power ?
