I doubt it can come close to my proper dedomed MF04S, even without my dual packs.

Who did the job on the led of your light, and what about Lumens and Candelas please?Is there a major difference?

I don’t like the interface.
On the K70 you had that nice ring, but on this one there’s just a stupid button. Not good for emergency at all. You need to be able to turn it on in the mode you want.

The one button UI is actually better for emergencies than the old style control ring.

The one button UI allows instant [one handed] access to any one of 3 different output levels.

Ultra Low, L/M/H [memory] and Turbo.

The K70 is a two handed light that is slow and cumbersome, especially in an emergency.


No,in case of emergency,I had to turn the ring one step only and I had strobe mode at once,which is way better.

Acebeam seems to advertise below the specs unlike all other flashlight brands. My K70 was measured at 470k cd as opposed to 422k that they posted. Have to respect that.

Astrolux on the other hand.. Their MF02 is posted as 3k lumens/ 1.5km throw which is nowhere close to reality. Jokable brand.

I measured the K70 at 610kCd.

Better than a simple triple click to access instant turbo???

Regardless of how you slice it, the K70 is a two handed light.

Just got my Acebeam K75vn with a power boost and Driver VNX3 from Skylumen Vinh Nguyen….. cant wait till these batteries charge and night falls…

Hoping for 1.8mcd+ at 30s! Too bad I have no way of testing to my knowledge… I ordered it with specs included though.

This is my first light with over 450kcd… talk about a step up!

This thing is fun. I hiked up a mountain last night with a friend to get at least 1/2 mile away from houses in order to play with the K75 and W30 without disturbing people. We probably caught the attention of someone maybe a mile away and he was shooting a laser at us and we shot back. It was like a super distant light war. Big Smile My friend became an instant convert into the flashlight hobby.

I bought mine from Andrew & Amanda. Tested with Texas Ace Lumen Tube calibrated with Maukka lights and a Sekonic Spectromaster C-800-U. Lumen measurements taken at 2 seconds from turn-on.

Acebeam K75 Power Mode Turbo 4,310 lumens 6809K -0.0047 DUV 69.9 CRI   -9.9 R9 44.4 R12 63 Rf 97 Rg
Acebeam K75 Power M4 1,538 lumens 5755K 0.0034 DUV 66.9 CRI          
Acebeam K75 Power M3 778 lumens 5480K 0.0074 DUV 66.7 CRI          
Acebeam K75 Power M2 247 lumens 5098K 0.0131 DUV 66.1 CRI          
Acebeam K75 Power M1 128 lumens 4981K 0.0151 DUV 66.3 CRI          
Acebeam K75 Eco Max 1,820 lumens                



The turbo mode with a -0.0047 DUV looks beautiful pure white. The lower modes with positive DUV has a greenish tint.

VOB measured 4658 lumens.

Now that several members here have modded with the same LED and estimated the output, 6300 lumens seems like a big exaggeration. Is acebeam usually this off?

Acebeam lumens are usually overrated but not this much. This is the worst Ive seen. Though their throw ratings are usually underrated. So far only Olight, Fenix and Nitecore lumens are spot on or conservative. Even Zebralight, Jetbeam, and several other well known brands over rate their lumens

for this price its not ok to have that big difference vs what they claim. sorry but they must put up more realistic lumens otherwise its not serious to throw up a number where actual real tests shows its nowhere close…

question is, can the led even be driven to closer 6000 lumens or ?

The max for this LED seems to be around 5k lumens.
