ACEBEAM K75 LED Searchlight Throw 2500meters 6300lumens Output Released

Is there a step down,I know,dumb question because the last 4 years this has been automatic!

When is the step down? How many minutes?

Can it be bumped back up immediately?

Thermal or timed step down?

Thanks

Any beam shots or any other information? This launch has been really lacking…

The K75’s beam reaches up to 2500 Meters, a professional grade searchlight in the palm of your hand! This powerful illuminator is able to generate up to 6300 Lumens of illumination using its one LUMINUS SBT-90 GEN2 LED as well as six output levels, produces a scorching brightness from 6300 lumens (Turbo) to 7 lumens (Ultra-Low), providing a wide variety of lighting options.

I like most people want to know how long this light will stay in turbo before stepdown. There seems to be maybe 3 pictures of this flashlight…

Cant wait to get it…but looks like to shoulder strap placement?

Acebeam how long will it take to step down from the max 6300 lumens to the next level?

It seems that Acebeam either does not know, or they are too embarrassed to share the number.

I did send few mails but up till now no replies from Acebeam.

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.
