Acebeam X75 Beam shots and Output Testing

USB C? What are you on about…

"greasy?"

What the heck?

It's only greasy when you grab the threads to unplug the cable without thinking haha

We get it. You're an Imalent fan. There's no need to keep comparing Acebeam with Imalent over and over. When members feel like you're targeting a brand, your credibility goes down. If you're going to point out faults of flashlights, then please leave Imalent out of it and then elaborate on your statements.

The power function of the X75 is a bonus feature to me since I have dedicated power banks that are more portable than carrying a big flashlight. If I were to go somewhere that the X75 is needed, then I would not need to carry a dedicated power bank with me.

PS: I have the Imalent UT90, MR90 and LD70. Not an Imalent hater.

yeah

really, this might work on some other forum. but that`s hard to find newbies here at BLF. there is no chances to sell nonexistent advantages of proprietary charger to anyone here.

looks like really biased opinion. especially strange when it is against brand, that is really respected here.

I am Imalent fan? Check my post please. I criticized all brand of flashlights. Don’t see any Imalent fan attacking me.

Besides greasy USB-C charging, Acebeam boasted in this flashlight. It doesn’t hit 80k lumens, that needs each LED to output at least 7500lumens.

And when you use it outdoor or even indoor, either as powerbank or charging it, dust will sticks on those threads.

If you really want to contribute, then give the X75 a proper review. Include pros and cons.

He got 77K lumens in his test which is pretty darn close. No one is going to lose it over a 3% difference.

What is your point? To prove that dust won’t stick on the greasy thread? You can open all your flashlights and expose their threads, you can easily review it yourself.

He used to time a factor of something 0.70 to 0.75, but to make X75 looks really good, this time he doesn’t times that factor. That’s why even his older Imalent MS18 hit 111k lumens, in the past, his MS18 OTF lumens didn’t hit that high. Flashlight output will only degrade year over year.

Use a bit of isopropyl alcohol to wipe the lubricant off the threads. Problem solved. :beer: :stuck_out_tongue:

I wonder if the X75 could be used as a 20K calibration light for spheres and tubes to measure big flooders… :innocent:

For me, PD charging is a great feature. I like my Imalent lights but not the chargers

If you watch afterwards Matt uses his Maukka calibration and only gets 57.9K, this is what he uses for all other previous measurements.

I’m looking into getting my Maukka calibration light tested for verification in a proper lab.

No please, the custom battery pack is bad, and I have to use the custom MS18 charging cable again? At least any USB-C cable can charge the X75.

I also have a 20,000 mah graphene power bank with a 100 watt usb-c port and a 90 watt car Charger. I just have to decide how important 5000K is or if I should just get the 6500 one

Why would you not use the conversion factor if your meter / lumens tube requires a conversion factor, then proceed to call the non converted measurements “lumens?”

The lumen output at 30 seconds from the calibration lights is relatively low (e.g. 270 lumens) and I doubt the accuracy of a DIY lumen tube when it comes to integrating light from these big flooders with 50,000+ lumens. A sphere may be needed.

Did he use the lux values for comparing big flooders rather than lumens?

Matt used his tube without Maukka’s calibration for 77,200. If he uses his Maukka calibration it’s only 57,900.

My Astrolux EC06 peaked at 26K and the X75 at 54K, but people say you need 3-4x the lumens for something to appear twice as bright, and the X75 in my photos looks at least twice as bright, so who knows. Marco at 1Lumen measured the EC06 at 16K with his sphere, so maybe these tubes are just not able to measured higher output very well. We will see what his numbers are when he finishes his review Correction: it was owen that measured close to 18K in a tube, so I really don’t know then

He used a custom built sphere. Maybe it’s more accurate. :weary:

I need to change the sensor in my tube because it’s not accurate over 1500 lumens.
