ACEBEAM K75 LED Searchlight Throw 2500meters 6300lumens Output Released

Does anyone know how this emitter compare with the CFT-90?

This page from Luminus' website may be able to help answer

has anyone ever developed a light with a belt worn battery pack option?

Impressive run times at the needed current………………

Thanks. They don’t have the SBT-90 G2 listed yet but seems like the CFT-90 can be pushed harder.

I wonder what flux bin they got. I’m sure Acebeam is not willing to share this info though. They seem to be more lip tight than any other flashlight company I’ve seen.

Given that the turbo runtime is the same 1hr45m on turbo power and turbo eco, one could assume the turbo steps down from 6300-3000lm after ~5 minutes like other large Acebeam lights. Maybe even sooner due to the massive current that’s being pushed to the emitter.

This is the about the same performance Vinh has been giving his MT70+ mods with the CFT-90, but now in a more refined package and probably more efficient driver, assuming acebeam went with 2S2P or 4P instead of 4S.

If the output is maintained at 3,000lm for the 1:45 runtime then they’re achieving a overall output efficiency of >110lm/w, IMO too optimistic for this emitter.

If Acebeam is pushing around 100 watts through this light, turbo is only gonna last like 2 minutes.

that would explain why such info isnt posted… :person_facepalming:

Are there any output / Vf tests of the SBT-90? I could not find any with a search.

Code please, thx

ACEBEAM K75 Ultimate Thrower LED Flashlight

Just login for this thread.

Does new K75 has square LED beside ???

The photos are so grossly over exposed/exaggerated. Look like short arc military search lights.

If it can run on Turbo for at least 2mins maybe… 3-4 yes. 5min instant buy?

I was considering the BLF giga thrower but this sounds more appealing for the obvious extra light output.

Sorry but just 1min of Turbo is useless for any outdoor use. Impressive though. when will they crack the 3KM mark i wonder?

Looks to have alot of meat on the body but maybe they can increase size of cooling fins on bottom area of reflector?

The big head design on this actually looks really nice. I like the heatfins alot. GT4 still looks best though but not sure if it will ever come out.

Yes, olight X6

This acebeam looks awesome. Hope it’s available in the UK soon

Why does the led cost so much??? Greed?

Maybe because it’s the second Mother of the first Mother of all LED’s Or maybe now it is the first Mother? :person_facepalming:

Or greed… :frowning:

ACEBEAM K75 available in UK

Will you offer same pricing for non-UK distributors in Europe? I have seen prices of EUR 319,00 here in Germany whereas YowCha! offers the K75 for GBP 225 which is about EUR 245 only. There are no customs / tax charges that may need to be taken into account.

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.
