Review of Haikelite MT07S NW Now with coupon code and Thermal image.

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! :smiley:

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. Couldn’t 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 it’ll 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 won’t buy an HaikeLite flashlight again before seeing a complete teardown, especially since HaikeLite’s customer service doesn’t respond to e-mail. :wink:
We don’t know if they took note of this problem and corrected it.
But i’m fine with Terry White’s review, he’s 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.

Just out of curiosity I did a search for machining MCPCB shelf and flashlight machining in general.

It was harder to find a light without of any brand without a similar flaw.. Or is it a flaw?

The models that I can find that have no mark of any kind were models that the shelf was added after the head had been completed.

I also asked the machinist were I work if he could machine the entire head without adding the shelf after and not leave any of mark, dent, ding, or anything of the sort...

He laughed.

I knew he would but I wanted to ask someone that does it for a living with over 40 years experience.

The head is machined from a solid piece of stock he assured me that it should have been a good deal smaller but other than that it is fine. He did not go into detail about how much smaller but did add that filling it is very simple and common.

I just though it would be fun to see how many lights out there may or may not have a similar process. Most were parts added after the head was complete.

I am by far no expert when it comes to machining (I wish I were) but I am at making sure heat is moving away from expensive parts. We have bearings and PLC's that cost thousands to replace so I routinely check for isolated heat. Any experienced machinist is welcome to point out anything the rest of us may not know, what you do is far from my area of experience.

I was surprised at the thermal images of the MT07S just as I was at most of everything about it. Even the very best lights have issues with heat. The MT07S handles it as well as any I have put the thermal gun on.

I guess in the end it comes down to personal taste or what some do or do not want or like...

Either way.... It is always lots of fun...

I have this light as well as the mt03 II and the sc02 xhp35. I am EXTREMELY PLEASED WITH THEM. Using a discount code, you can have an xhp70.2 floody thrower with great cooling and simple single button control for under $75.
This is not a cheaply made light but rather a nicely machined light that is pretty impressive.
If you handle and play with one for awhile, you will be won over.
