It’s hard to pull any useful information from that video (that we don’t already know), but one thing I noticed was that the 4 battery springs on this 70.2 version are not bypassed at the factory. This would seem to indicate it’s definitely not going to make 24000 lumen. I wish they didn’t over rate it so much. Still, it seems way better than the original light.
Yep. Unless they changed the springs for something much more conductive, which I really doubt, it’s never going to come even close to 24k lumens.
After bypassed springs there is only 1100 lm more .
I’m not used to complaints about only 1100 lm gains. 
BTW, seems like Samsung 20s is a good cell for this light.
It can be had from Vapcell (Vapcell Black 2000 mAh), but it’s a bit expensive.
Is there a better source?
not sure many can see the difference between 17000lm and 18000lm, and are these the startup lumens? If yes, both should drop quite fast too.
Sure….in this light such gain ain’t large. But that actually tells a lot about how powerful MT09R is.
Did anybody try to rised the current in to the white led on charger?
The charger output is about to 50-70 lm.
I suppose that there is synse resistor.
100 = 10 ohm is before mosfet 2300

I did ceiling bounce output sag measurement on the output for new version Haikelite MT03 that I estimated to be about 12k lumens compared to my other lights. No temperature chart here, I was lazy to use thermal meter, it is getting very very hot in one minute. With freshly charged batteries and in about one minute, its output dropped from 12k lumens to 11k lumens.
Sure it is very powerful after tuned by TA. And GB price remain the same, which is very good news to us.
All true, but the problem remains that the 24000 lumens declared are not achieved, even for technical reasons of the 3 xhp 70.2 leds or something wrong? Thanks.
Haikelite and many other brands love to do that. I guess they want to attract uninformed customers with higher lumen number.
For us, we buy knowingly it is unreal theoretical startup LED lumens, it is not ANSI OTF lumens. They never declared it is ANSI specification to anyone.
It is not necessarily a bad thing for us. If they can earn extra money from uninformed customers who don’t really care about lumen, they can stay in the business and continue to come out new and innovative flashlights, it is win win situation.
No, it’s a win-win-lose-lose situation.
Because uninformed customers lose.
From TA’s conversations with Haikelite, they don’t even have their own lumen sphere to measure. I’m pretty sure their advertised lumen was taken from TA’s previous measurements in his MT09R modding thread when his lumen sphere was calibrated too high. I really think all manufacturer’s that can’t afford to buy a $10k plus professional lumen sphere should just buy TA’s lumen sphere with the current calibration. That way at least they know what their own lights are producing.
With that said, the MT09R really is a great light. Very nice floody beam that also throws pretty far. Whatever the actual lumen is, you will be impressed with its sheer brightness.
There were quite a few cases where we verified their numbers to be grossly exaggerated. Even more than doubled. They never corrected them.
Here they may have taken TA numbers. But they rounded them up. And they surely know that removing spring bypasses reduces output. And I think that someone found that they use worse LEDs.
So no, their numbers are not exaggerated because they are unable to get correct ones. They are intentionally misleading.
So maybe you should not buy it, or maybe wait a few tests to know the exact values
of light.
I already ordered. I did so with full awareness that I don’t know the output. I find it very likely that it will be well worth the price and accept the risk that it may not.
I don’t like being lied to. And I don’t waste a good occasion to call it out.
But it doesn’t stop me from making business when I think the business is good.
In a way I vote with my wallet, but weakly. I don’t refuse deals with dishonest sellers but take the uncertainty into account when making decisions.
I think you’ll love the light Agro. :+1:
I hope so. 
MT09R is great light, relation between price and power is great.
From 3x xhp70.2 and 3x deep reflector the real range is 600m.
For 125$ you get 17-18 klm on output real neutral light ( 144lm for 1$ )
If someone want real 25 klm just buy Olight X9R : 600$ for 25 klm ( 42 lm for 1$ )
Probably in cool white and also the range will be closer.
Yes, but what else is new. Everyone knows rated specs are almost always exaggerated.
For those that want to know real numbers there are places like BLF and CPF (?) That will actually test it.
I think the average consumer does not care about exact numbers. It says 24,000 lumen. They buy it and it fries their eyeballs and they say, yeah, that is sure bright! Must be 24,000 lumen. Lol
It is always buyer beware.
