I have been using it for about 4 years to fill minor F-ups in Aluminum, it machines really well once fully cured, so I tried it with and in my lightsā¦as a potting material,body filler and to epoxy battery tubes together and such.

Here is a pretty Extreme Test, I guessā¦
Thank you very much. I just placed my order... I remember my dad using it and it always worked well.
Thanks again...
This is after 10 minutes on turbo. You can see concentrations at the head but the heat is moving out and away... Temp is set to Fahrenheit.
The best pary I totally missed. 7 to 8 minites after turning the light off no part of it was avove 90 degrees F
I have several from when I first turned it on up to that shot above..
I will try to post the others when I get home...
Only 46 Celsius after ten minutes is pretty good
awesome thermal images! 
Pity, that those images proves nothing about hole under mcpcb I asked.

Hi Terry, may I know what was the highest temperature?
The picture you shows seems to have abrupt temperature change from the highest temperature to surrounding. Couldnāt that mean heat get trapped?
No it proves nothing about a totally different light that I have neither used, held,touched, or tested.
It does prove without a doubt that at this light's highest setting after 10 minutes it is controlling the heat very well.
This thread is the MT07S. The first and only light from this brand I've tested and agreed to review.
I only post or discuss what I can prove about the product I was asked to evaluate.
It makes no difference to me if they had prior issues with other lights... What company doesn't?
This is a young company and mass producing lights of this type is no easy task.
I can not and will not speak any further on the matter of any light I have not tested myself.
The bottom line this is a review of my findings for model MT07S and it has easily shown to be a solid performer that does everything the manufacturer claims it will do.
I have proven that in every way I have available to me including getting permission to use a $4000.00 Fluke thermal imaging gun fully calibrated.
This light is a total pass and a bargin with the discount provided.
I can find nothing wrong with it at all
That reminds me... I discovered you can go to turbo from any setting even off. Just double click.
For those interested in this light. My honest and true 30 year experienced opinion of the MT07S is if you like it... Buyit. It is worth the retail price and worth more than the discounted price.
Thank you all for reading and support.
No.. top right show the highest recorded temp. That was 118F... A couple of minutes later the same exact spot had dropped by 4 degrees down to 114F. So it ismoving heat.
I was surprised that the temp did not go higher.
Cool down after shutting it off was much faster than I expected. Back to around 90 and 91 degrees after a very short time. So it's shedding heat.
do you think itāll handle a a resistor mod pushing 6000 lumens otf well? 4500 is ok but more is always better!
Thanks for review.
Mine is on the way to me, but my high drain battery might come late as it is shipped via sea.
It seems to control heat well at 4500...
I will not say it couldn't. I would test it thoroughly and often. You can use just a IR gun to get basic temp readings.
Might be fun to find out...
Is there a different in output between using Samsung 30Q and Sanyo 18650 GA ?
I honestly can't say... 30q's are my top shelf 18650 cell of choice.
I have a couple here and there of other brands but not a set of 4 of any 18650 except 30q's...
I also should have mentioned that he CW version of this light already has 5000 lumen output... 1K more I would think would be fine.
Personally, I wonāt buy an HaikeLite flashlight again before seeing a complete teardown, especially since HaikeLiteās customer service doesnāt respond to e-mail. 
We donāt know if they took note of this problem and corrected it.
But iām fine with Terry Whiteās review, heās free to do it like he wants.
I can't speak at all for service and if they have an issue with that then if It were my company I would handle that real quick. It can make or break a company.
As for the light... At least the MT07S, at this price even if it had a bad spot because of some guy who does not have a clue what he or she may be doing... The whole, dent what ever we want to refer to it as can be easily fixed.
Ahhh I just happen to stumble onto an answer for anyone wanting to know.
There is a thread that was started a few days ago. Someone is modding an MT07S and you can easily see everything you would want to see.
The thermal shots of my sample show better heat management than lights costing 3 or 4 times this amount.
I have shown what I can to show I believe it to be a good and stable light... And compared to others of this type a huge bargain...
If the one I have here shuts down or has some problem I will be the first to post it. For over 2 weeks now not even a hint of a problem.
I will swap the driver this week and change the thermal paste si I can take pictures if you want. See my modding thread.
Terry review is good because he has interesting thermal pictures.
I would very much like to see any modding you do. I really believe this light can handle a good bit more than stock.
