Acebeam K75

guys dont judge the book by its cover.

“Still” no news…………

No,I’m not impatient, not at all!

Cheers,

The only thing that would make me really consider it is if it was powered by 21700 batteries, since the diameter increase would be negligible.

The BLF GT needs to step up its game! Lets encourage them to make a Turbo Head… say 180-200 mm diameter and deep reflector :smiling_imp:

Edit, found this other picture from this Spanish site https://linternas.net/novedades-acebeam-2018/

The Acebeam advert on the side says:

2569m
6300 lumens
Luminus SBT-90 Gen 2.

Acebeam has added the K75 to their website. And with some impressive specs.

Acebeam K75


Here’s the beamshot of new K75 with sbt90gen2 led, and now this kind of led can only be obtained from the LUMINUS laboratory.

impressive… blf gt has a real competitor now. what can be said about the led, anything special about it?

Where is the pdf for this new Luminus emitter, I can’t seem to find it? Wonder how it compares in surface brightness and power handling to the likes of XHP35 HI, Black Flat, CFT90? According to acebeam’s product page, the light doesn’t step down at the turbo output? Wait, nvm, it has a form of intelligent thermal throttling.


SBT90GEN2 hasn’t been mass-produced yet because there is not enough demand, while several Chinese flashlight manufacturers have been testing led samples.

Is this the SBT version of the CFT-90?

hmm, interesting led, must be expensive af
i wonder how this led compared with xhp70.2 dedomed

Looks like it can sustain only 3000 lumens, 679800cd. Still pretty good considering the weight (only 843 grams!). Price is better than expected and it destroys every other thrower. I think Acebeam is gonna sell a lot of these.

Not sure if 3000 lumens is sustainable or not, it’s just quoted as the highest output in eco mode. Thermal regulation still might kick in. 3000 lumens constant at 2 hours definitely doesn’t seem right, unless this LED is just a gigantic leap forward in efficacy.

What’s interesting is that this host initially had a 150mm spec’d reflector. Now it’s only 125mm. Wonder if typo? If not, MF04 still has a larger reflector.

Wow 1.56MCD at 6,300 lumens is just crazy! I wonder if the CFT90 will throw even farther.

Turbo turbo turbo.

I’m ok with up to a 220mm head. It would look stupid and I’m sure I would be made fun of, but…I’m ok with that:-)

Just wonder how long it will take to step down from the max 6300 lumens?

13 second quick and nasty beam shot video on the tube.

some impressions from reddit… says that 1 minute and already too hot too hold… thats just bad for a light this size…

Copying first impressions from other forums:

UI is a little sluggish to me. Not as fast to change modes or go straight into moonlight compared to my other lights— whether it’s driver VN, Anduril, or Zebralight.

Hotspot and corona are big, around the same size as the hotspot and corona of the Cat6 with XHP35 HI. A very useful and thick beam. I have not taken it outside yet.

Heat is well managed in eco mode. 4 minutes of turbo (3000 lumens) and the light is just warm around the e-switch. If there is any thermal regulation ramping going on, it’s very smooth subtle— can’t really notice anything.

In power mode, turbo gets hot instantly. By 1 minute in, it’s nearly too hot to hold, and the thermal control starts ramping its output down. The 3000 lumens seems very usable, while the 6300 turbo is just a ‘lemme show this to my friends real quick’ type of mode.

I’m not sure why the heatfins half way up the taper of the head, the placement makes no sense. Aesthetically it’s cool, but the heat doesn’t spread to the thin shell holding the reflector in place. It first starts at the shelf of the LED around where the switch is at, and then goes towards handle first. I would have preferred something more like the way Maxtoch does it with the XPro, where there’s a solid chunk of fins just below the reflector. Not having the fins half way up the taper would make the light less top heavy as well. The ones around the button are thick and deep though, and do a good job.

The 2500 lumen output mode has no heat problems whatsoever, a wide beam, and throws 5-600kcd, and has flat regulation for 2 hours. That’s extremely useful.
