ACEBEAM K75 LED Searchlight Throw 2500meters 6300lumens Output Released

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.

Just received my K75 yesterday from Andrew & Amanda. Haven’t really had time to play with it but just did a quick lumen measurement with the TA lumen tube calibrated with Maukka lights at turn-on.

4,310 lumens at turbo in power mode
1,820 lumens in Eco max.

I did not take any measusrements at 30s. Lumens fall after turn-on so 30s should be much lower. I tried both the stock Acebeam 18650 protected cells and Keeppower VTC6 3100mah protected cell and got the same results. They both use the Sony VTC6 underneath. For anyone getting higher measurements, what cells did you use? I wonder if I got a lemon or is Acebeam ratings severely inflated on this light. They are not as good as Olight, Fireflies, and Emisar when it comes to lumen rating accuracy but nothing this bad. I measured the Acebeam TK16 osram version and got 1100 lumens, which is not too bad.

The K75 is smaller and much lighter than I expected. The head is slightly smaller than the R90C. I can fit it completely in my 4” TA lumen tube for an accurate measurement. I think it is very well designed. I found a pic that it is compatible with the X65 8-cell rechargeable tube for extended run times. I also tried an X80 4-cell tube and it fits in the K75. However, the K75 tube does not fit in the X80. Weird.

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

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.

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. :smiley: My friend became an instant convert into the flashlight hobby.

I wait to hear from you about the possibility of modding a BLF-GT, putting in, this SBT-90 gen2 led. :slight_smile:

In case anyone is look'n for it, if not already posted, Wendy emailed the SBT90.2 datasheet to me, I posted it here: SBT90.2.

Aaaa, photos from Nokia 6600 :smiling_imp:

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.

lumens seems rather low vs advertised ?

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.

Has anyone experimented removing the cells from the carrier/tube?

I would be leary to get a light where I cannot change the battery and use standard off the shelf 21700’s.

Yes, Acebeam sells replacements carrier/tubes but for how long?
