Bangood currently offers the MF04 at a coupon price of US$158.00 including shipping!
    i got both lights and the K75 is a much stronger better thrower then the MF04 with much more flood. For me the K75 is in another class.

    Does anyone else have experience with this new K75 who can shed further light on its power compared to previous heavy hitters? How is it compared to the BLF GTvn CFT90? The MF04vnCFT90? The TN40Svn, Acebeam K65/mini?

    The German forum has done a passaround, and there are tons of comparative reviews, comparing this light to the lights you mention, and to more than a few others in similar classification, such as the TN42Vn CFT90. I will not be a spoiler and specify which lights this one outperforms, you can see the pics in the other forum(s).

    I am still waiting on availability of the K75 in the USA from my favorite supplier. If he is not going to offer it, I will have to go with my second fav supplier.

    This is what I envision from three lights that I have, and the K75 that I do not have yet, ranked in order of increasing beam width: TN42, K75, X65, R90TS.

    With a light that is larger/weighs more, you get more power-thrower. With a light that is smaller, you get narrower dedicated throw.

    There are so many possible combinations/permutations of single or multiple emitters, large or very large reflector, etc; that is why I have so many lights!

    Matt just posted a great K75 video with lots of beam shots and comparisons to other big throwers like the GT and MF04.

    I received my Acebeam K75 27 hours ago. I am happy with the performance increase over the K70 and the TN42. Compared to them: Some more of everything: Some more emitter, some more head diameter, some more throw, some more beam width, and some more light on the target.

    roma58 has just posted his comprehensive review on the other forum, too.

    Its a solid 2500 lumen spotlight, beats grabbing the 10pound Streamlight HID lightbox. You can run at 2500lumen output and get the job done. Loafs at 2500 no problem.

    Its crazy light and small for the output. In a few years HID will be obsolete, unless you need 1m Cd for long periods which the litebox will do, the 556kCd 2500 does the job and for most there is no reason anymore to go HID.

    They could market this light for LE,FF,MIL as a quick grab spotlight no problem.

    Would love to see in the future a version that can sit on a charger.

    Another nice review was posted yesterday in the German forum by user FrankFlash. The very informative review includes comparative beamshots with K50, BLF GT XHP35 Hi Nw, and HID Maxabeam MBS 450 HP. The very illustrative beamshots show much more light on the target with K75, but the reviewer reports more self-glare in high humidity weather with the additional lumens. HID beamshot shows much less self glare, but much smaller illuminated area.

    Check how much the lux drops at the next level in the specs!!!!

    Thanks for the helpful suggestion but I'll wait until an led light comes out that can maintain its high level for more than a minute, instead.

    I measured my K75 using Texas Ace Lumen Tube calibrated with Maukka lights at 2 seconds:

    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, Keeppower VTC6 3100mah protected cells, and X65 8-cell rechargable battery tube and got the same results. 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, Fenix, 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 tried an X80 4-cell tube and it fits in the K75. However, the K75 tube does not fit in the X80. Weird.

    My flashlight guy measured my factory specimen thusly: otf 30 secs: 1.57Mcd and 4,800 lumens and 2,506 Meters. He and I only use protected cells on a very few selected lights that require them.

    My personal observation is: More range than K70/TN42 and X65, and much less self glare at full range than X65. The beam diameter, glare-free crispness of target and max range are exciting to behold, and nothing comes close. I searched the world wide web for posted comparative beamshots, and those also show K75 is definitely the current led dedicated throw king.

    We bought a new K75 to try out. It was a nice light, but just didn't do anything for us.

    For use around the farm and property, the X65 is still the king of all-around lights.

    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 2s.

    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 is noway close to the stated by acebeam , how come? for a price this light the lumens shouldnt differ more then 3-400 max. otherwise the rated lumens is a joke and u feel ripped off buying such light.. come on acebeam, put realistic lumens not made up from thin air...

    I got mine five months ago, and I bought five other lights since then, and out of the 25 real performance lights in my collection, this light is the most exciting long distance light I have seen.

    What this light does to distant targets is still very exciting every time I use it.

    I've had my new K75 for a little over a week now. Yes, it is a monstrously powerful light, but one needs to have a very large open area to really appreciate how powerful it really is. What I find most impressive is one does not only get the insane throw from it's super tight beam, but the spill is large and bright enough to make it a very useful light and not just a one trick pony.

    The only real issue I have is, like several others have reported already, the LED tint is quite a bit green on the lower brightness levels.

    Yes, and counterwise, they have to maintain that power. There is no "low" mode Haha, if you will. You got 30 minutes of light, a couple thousand hours of bulb life at that power level, limited battery life and enough weight and price two k75s should be used mounted together (take up less volume too) , and finally they are free market lights, not limited production unavailability lights you have to jump through hoops, register ownership and pay for.

    Said who? People with cardboard boxes and 1 lux meter for lumen spheres? Measure this in a 10,000 dollar lumensphere, then tell me it isn't at least 6,000.

    In fact I did the math, for this reflector to get that throw the surface of the LED must be at least 6,000 lumens to get the required candela from a multi-million candlepower intensity.

    Every single one of those reviewers uses a box with less than 3 lux meters. If you run the math 1.5mill candela isn't possible with the candlepower @ the LED from 4400 lumens, and that size area reflector.
    Vihn 'Win' has the most accurate, a sphere with a refraction mylar cover over the lux meter reducing direct lumen over estimate while maintaining most of the lumens. His doesn't cost 1000 dollars and has only 2 lux meters.

    No matter what, 1 or 2 lux meters does not measure lumens, especially not with outlier lights (throwers/flooders).
    Acebeam used a 3rd party lumen sphere and reverse-calculation from the power to the LED. The LED must be doing over 6,000 lumens and with a 7% reflector reduction and 3% additional from that (about 2.8% after the first number) you get around 6,000 lumens. You are free to look up the luminous white sbt90.2 specs to see stated size, and lumen output, and then take the lumen output and find intensity (candlepower), then find the measurement for the LED intensity in the spill or at the lenses of the light and find the output from said distance from the LED, then the mathematical lux on the surface of the LED, then back to the area to give you lumens.

    Or just see how hard the light is driven, use Luminus figures to determine output @LED, generalize a 8-10% drop in output OTF.

    All these have been used in other areas of this forum. An experienced moderator can probably point you to the right page.

    Lumen boxes that m4d m4x and VN and people use can not measure true output, and it is totally a myth that the relative output is accurate as well. Only truth to their measurements will be VS a very similar light like the BLF GT 90. Then I would believe it but it was also much lower than claimed meaning the boxes are feeble minded generalizations never to be taken at face value.

    Yup, 4300 to 4800 lumens OTF is about where these things land once warmed up.

    And most are near the 4300 end of that.

    If we could obtain all measurements reliably from hypothetical mathematics, there'd never be a need for any measurement devices. Even if they're not perfect, I'd use them over a mathematical equation making many assumptions, every time!

    Imagine disputing and contesting consistent, objective, verifyible results that were obtained by Six independent sources, sources who all have shown consistent, accurate results in the past, across Six different samples of said flashlight, and instead ask us to ignore the hard data, and trust a math calculation with a bunch of hypotheticals.

    Then imagine telling those very people who's actual test data conflicts with the super duper hypothetical math equations they cooked up this

    "Lumen boxes that m4d m4x and VN and people use can not measure true output, and it is totally a myth that the relative output is accurate as well. Only truth to their measurements will be VS a very similar light like the BLF GT 90.
