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

Isn’t that hole there on purpose for stabilisation during machining? So all samples have that, and it’s not a machining defect?

It’s a defect in the sense that it shouldn’t be there if properly made. I don’t know the exact processes, but the proper set of steps results in a flat shelf allowing the entirety of the led mcpcb to make contact with the shelf.

Having some 25% of the mcpcb not making contact in the most critical area of a heavily driven LED is Not good.

Yes true. I do wonder whether this centre hole is present in Haikelite’s CAD drawings. Perhaps it’s not there at all, and the manufacturer just did this for production reasons without consulting Haikelite…

Almost looks like when it started it was too deep then corrected quickly.

Surely someone is not turning all these manually.

Thank you for sharing this review. Based on another feedbacks, I was also a bit worried, but I still can’t wait to get my sample (hopefully only in a few days).

I have to admit that this light really surprised me.

I expected from the research I had done prior to it's arrival that this was going to be a tough review.

Once I noticed that I had to search for negative things to point out I had a blast just playing with the light.

Is it the greatest light on earth.... Of course not... But is it worth the price for what you get (at least for sure what my sample is)? Yes...

It totally is and I would purchase this light. With the sales and coupon codes making the price even less I may stock up a few.

I have several co-workers that see lights I have from time to time during testing and they almost always ask where to get one. Once they find they need to order online they shy away. LOL if I have some on hand that I got a good price on... Well I think you can see my point.

I am glad you got something from the information. I can promise you that at least my sample so far is trouble free and is as advertised in lumen count.

This is a good point... I got my sample from BangGood and I have not taken the head assembly apart. The LED is almost perfectly centered and unless I have a need or reason I like to leave them perfectly centered.

Yeah if I sit here for awhile I will get it just as centered. It may take a few minutes or it may take half a hour.

I want to put the head in front of the Fluke thermal gun we have in the shop at work before I do anything. Once it warms up a bit I should be able to easily see where the heat is and if it is stationary or if the pill and fins are doing what they are intended to do.

They will not allow me to use one of my own SD cards to record the images but I will try taking photos of the screen. This is also not allowed but I have been there awhile and most of the guys in the shop like watching when I do this so I can probably get a picture or two with my mobile phone.

I don't have any direct contact with Haikelite at the moment.. I may remedy that soon as well.

If anyone does this is a good question. It is possible they do not know.

Gotta know lol... Where did ya get it.. I have looked in spare time for that for several weeks lol for a light I am going to call Frankenstein if I ever get the time to complete it.

Either way I would love to keep a couple of tubes on hand.

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 lights…as a potting material,body filler and to epoxy battery tubes together and such.

Amazon…. Amazon.com

Here is a pretty Extreme Test, I guess…

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! :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.
