fwiw I put the 9k X7 in the tube for runtime tests. Tiny fan kept everything just fine, but I imagine even without the fan wouldnāt be an issue.
I carve out a few hours and chill next to the light while I listen to a podcast or something like that and record temp and lux via timed alerts.
Yikes! If I tested all modes, that's 228 + 32 + 18 + 10 + 8 + 98*24 hours, or 2,648 hours.
Ok, without moon mode it's only : 296 hours, or 12 1/3 days - not bad 
. I'd only lose 8 days of income, several $K there, (I only get paid for hours worked), and no sleep of course 
.
Ok - maybe only turbo... Just one full work day or long evening... 
Might have to figure a way to work @home while this goes on... Hhhmmm, or be able to bring everything into work and watch while typing away... Might be do-able

There are probably expecting to sell A LOT of these lights. 
Now we waitā¦ā¦.for the price.

i think this light can very well compete with the acebeam k60 as far as performance. 5000 lumens and 132kcd is respectable. but i agree with what dbcustom saidā¦its pretty much last years numbers. I would have liked to see 6000 or more lumens. considering the size of the heatsink, i would have expected longer runtime than 5 minutes on turbo. most lights can only run turbo for 2-3 minutes, but their head and heatsink is nowhere as large as this mt07. my modded tn36ut can run at 8000 lumens for 5 minutes, and its alot smaller.
iām not sure if haikelite will be coming out with a smo reflector for this light, but if not, shaving the dome will be a good idea for a light like this. vinh said shaving the dome off of xhp70 on a op reflector makes the beam perfect and completely eliminates the donut hole effect. at least this is what happened with the k60.
i like the fact the light is under $100 and great value for what you get. the double switch and ui is great. and the easy to mod makes it even better.
but the thing i would like changed is the heatsink or the handle. im guessing its too late now to change the design up drastically. but i think the light should have been 1 inch shorter at the head. it seems very top heavy. and since i think the diameter of the reflector matters more than the depth for throw, it would have been very minimal decrease in the throw department. this way, the user can hold the light by the handle and the smooth surface where the switches areā¦instead of holding the light by the handle and to the heatsink.
ps. the price has been listedā¦.its $95
Very nice review of a very nicelight!
(nice they engraved Tom E on it, can we order them with a custom engraving too Lol joking)
Just turbo would be nice. Not even the whole run would be necessary. It would just be good to be able to see how far they drop it down in order to achieve 8 Hours.
That has to be a ridiculously massive drop to squeeze out that much time.
For the runtimes, I'm getting curious now. I'll ask them as well, but still would like to do an independent test.
For the S/N, I was trying to figure it out. After the year it's a letter, 3 digits, letter... repeating... and the #'s are 0002, 0003, 0004, and the letters are: H-A-I-K-L. Interesting... There were a couple more review units sent out. I've been pm'ing with bluzie and he's getting the MT03, but got messed up in customs so still another couple weeks.
It might have extra data in it like a vin.
Added a turbo mode discharge curve in the OP. About 7 minutes in, there's a big drop, then the rest is a slow drop off
Thank you Tom, very much appreciated.
Couple more Qās if thatās okay:
Can you bump it back up into turbo after the stepdown?
Does it always drop at the ~7 minute mark after activating turbo or is there thermal regulation?
The bump up should work, but not sure exactly how - probably just a click on the mode change button but whether it goes into turbo or back down to lowest mode is the question. Cells are at 2.9V now and still getting the BLUE LED blinking, so according to the specs, that's at 9% or above - not sure if that's right.
Earlier I did a 6 minute test and it didn't drop down. In the run, it dropped at the 7 minute mark exactly. No time now to test - got an appt for the car, then to work. Think the best test to do would be run it again til it drops down, then turn OFF, back ON turbo, and being that it's hot, see if it drops at 7 minutes again (timed) or earlier (thermal sensor).
I gotta do some R&D on charting tools - Excel is very frustrating to control... I got external temperatures to plot too.
Thanks for the info.
Yeah Excel can be a pain to get it to do what you want.
To get the axis right I believe in the axis format I changed to dates then did some minor tweaks to get proper spacing and numbers.
Dual axis for outputs and temps is more complicated and very fickle. Should be some helpful vids on YouTube though.
Iām a bit puzzled here. The light drops down to 2000 lumens after 30 minutes, even though this light has got huge heat sinking. Olight X7/Thrunite TN36-UT can produce 4000+ lumens continuously with much less massā¦
Well the Mt07 does about 4800lm for 7 minutes and drops to a little over 2k lm.
The X7 does about 5500lm for about 10 minutes before dropping to a little under 2k lm due to thermal regulation.
Ambient temps and general settings can be a factor. I suspect the MT07 is a fair bit cooler at the time of the drop and the drop itself may be timed.
Where did you see the Olight X7 running 4000+ lumens continuously? If its not true, why would you make this claim?
What about the TN36-UT running 4000+ lumens continuously? Where is this tested, documented, claimed, proved?
Continuously is a bold statement without a time frame - minutes, hours, days, til the cells drain?

The test were done cooled. However, without cooling the X7 does indeed stablise at 2000+ lumens. Although the efficacy of three XHP70 at 2000+ lumens is better than a single XHP, the MT07 does have so much more mass and surface area than the X7/TN36-UT
True. But does it make sense to have a timed drop to ~2000 lumens? Indeed ambient temperature does make a lot of differenceā¦
Edit: ok, another question related to this. According to Haikelite, this light has got ātimed thermalā regulation. What is this? If a light is regulated by temperature, what do you need the timed regulation for?
I interpret ātimed thermalā regulation as just a timed output drop. It probably does not have a temperature sensor. The driver is not as fancy as the X7. I donāt see this as such a big issue. In most use situations you can just pop it back into turbo mode if you want.
This light is very different from an Olight X7 in many ways - thrower vs. flooder, more efficiency from 3 XHP70's vs. one, etc. The X7 is comparable to the MT03 which is a smaller in size and weight from the MT07.
Checking my notes, there is a 4S variation of the MT07 - the one reviewed is 2S2P. I opted to review the 2S2P version. The 4S version is said to have full current regulation, shorter run times, and recommended to use protected batteries.
Also found in my notes this from HaikeLite:
Timed Thermal step-down
On turbo mode the light will detect the temperature after 5 minutes, when the temp is higher than 55 degree after 5 minute, it will step down to high. If the temp is not over 55 degree after 5 minutes, it will stay on Turbo without step-down.
So, I'll try to confirm it this evening. This explains why it lowered at 7 minutes, I had no extra cooling - fan or otherwise during the testing. Basically, if it steps down after 5 minutes, you can switch back to turbo and get another 5 minutes of turbo level output.
