Closed Official Haikelite MT09R *UPDATE Now including TA's Pricing for Emitter Upgrades* Closed

15000 lumens at 90kcd is very good flood and throw. I can imagine that. :beer:

I also agree the MT09R 70.2 version has on of the most practical beam profile of any flashlight. Great flood to enable you to clearly see your surrounding and also very good throw so you can get a good view far into the distance. The beam profile is extremely fun to play with both indoors and out doors. I added DC-Fix on mine to further smooth out the hotspot and right now the beam is buttery smooth and I don’t think the throw is reduced. I love this flashlight especially with the 80+ CRI!

The only thing about what they are working on for sure is that they plan to test and test so be sure it is as close to perfect as they can get it.

The Capacitor removal seems to be working fine. I have a couple here that I test constantly and so far they work without any issue. But do just be careful of the heat. The 70.2 really heats up fast on turbo. To my knowledge this will be addressed as well.

If it is the decision of the Haikelite partners to make another driver then I am guessing that if you already have this issue you will be shipped a corrected driver. Again I say if that is their decision.

Almost forgot.. I didn't post it here on BLF but I have put the SC02 on a pretty decent sale for any of you that may be interested.

By looking at how Haikelite solved MT03 II issues with new driver, I think Haikelite is for sure working hard to solve MT09R driver issue right now. Most likely they already have the solution and performing more thorough test now.

Haikelite has the willing to improve their design and product. But I just don’t understand why they want to keep boasting their light candela number and then rush their product out to market with problem and solve it later. Make me think that they are racing with some competitor product in their fantasy that has 300kcd 6000lumens performance.

Now after a month of waiting, I got a response to my question from Dale.
And now the tracking works.

I think he sent out the flashlight yesterday and not before CNY.
Now I get tracking results:
17.03.2018 Beijing (China) Beijing (China) Received by China EMS Shipment received

Thats very disapointing.
A month ago I asked dale for a refund if the flashligt is still in their warehouse. But no respond.
And now after my next question, he answered and I think he shipped it out some days before.

I want to get honest explanation about the drivers and shipping status and when they shipped which flashligt.
They told us all flashlights were shipped before CNY, but that could be impossible the truth.

I want Dale to expain something here.

This groupbuy came with special color and tint selection. I don’t know for sure you can just cancel order like that.
If the light is built according to your custom selection, although it was not shipped due to CNY holiday or whatever reason, it will be tough to cancel that.
Of course, sellers don’t like order canceled, so they will use whatever method to avoid your cancellation. Even it is hard to cancel order with GearBest sometimes.

why not? if they couldnt get all lights out u must understand frustration on some users not getting any info if light was shipped etc… we were promised that all lights will go out before holidays, sadly some didnt i would in same situation also ask for a refund…

If u promise a light will go out before a certain date but for some reason it does not, then the buyer has every right to ask for a refund then if u ask me….

come on guys lets not bash the manufacture.

just wait and give them a chance to rectify the issues.

I think they are working on the driver to address the problems.

I learn to be patient from BLF GT light :stuck_out_tongue:

Thats no bashing, that semms to be facts.

I got my tracking number before the holidays and thought it was shipped. But it seems that it was shipped weeks after holliday. And If the flashlight has not left the factory, it is easy to ask for a refund, because they heave not yet payed any money for shipping.
Thats the european thinking about it.

It would be ok if they give a notice, that there is a delay in shipping, but no one got such a message or nothing were posted here officialy.
But if they send a tracking number in early febuary and promise in this forum that all flashlights were shipped and send it out in the middle of march, it feels like they are lieing to me.

Wieselflinkpro,
If you still want a refund you can get one via paypal. You might not get it until light is returned to China, but paypal will make manufacturer cover return shipping cost. If you need help PM me.

Any news about chargers?

I can’t speak officially but I have had several people message me so I figure I will tell you what I know about the driver situation.

Yes, as several of you guessed, Terry and then Haikelite brought me in to look at the drivers issues with the MT09R.

After some diagnostic testing and a bit of luck I found that the extra capacitor that was for some reason stuck between the LED V+ and the LDO was the cause of the issues. Removing it seems to have solved the flickering and “tailcap” issues. Although it is not a perfect fix, it does seem to work thus far. I still want to know why that was put there.

Haikelite then asked me to start from scratch and design a driver for the MT09R. I have been working on it for the last 2 weeks. It will be a fairly simple TA FET based driver for simplicity and reliability. With a few tricks like dual FET’s for more current handling if needed (only one will be populated from the factory I think).

It will also have some extra voltage spike suppression control built in to handle the massive currents it will be dealing with.

I got the first prototype built Friday and have been tweaking the firmware and driver ever since. It will naturally be running REAL NarsilM 1.3 which is light years better then what the stock drivers had (only the S42 comes to mind as being worse in recent memory I am sad to say).

In testing so far it is working great, FAR FAR better UI and performance as well. I swapped out the xhp70.2 LED’s for some 80CRI 4000k emitters and I am getting 23k lumens peak out of it now. It is also pulling around ~40A of current at 6.6v, for over 250W of power!

Needless to say it gets silly hot so almost a full day was spent tweaking the thermal control settings to keep the heat in check. Sadly there is no way to do it “smooth” with this much power, it can go from 55c to 65c in under 15 seconds. So there is just no time for a nice ramp down. It just drops the power in a big hurry.

It works though, in testing even with my mega light it will reach about 55c and then start stepping down and usually the overshoot tem is still under 60c, which is “Safe” (aka, your reflexes should be plenty to keep you from burning yourself).

The driver will just be a single channel FET driver for production I think as the 7135’s have proved unreliable at 6V. It becomes a bit of a lottery, some work and some don’t. Only way to know is to try it which is not production friendly.

That said I talked with Del and I am making a V2 of the driver that could improve the 7135 reliability. It still needs to be tested though.

The 7135 will gain you a lower moon mode, smoother ramp in the low modes and better efficiency in the low modes. If you do not use the low modes much, then the 7135 will not do anything for you.

I will be selling some hand made and tested drivers with the 2 channel 7135 design if anyone is interested. I just need to figure out how many to build.

I have to say, I really like this light once it has a good driver. I can see it getting a LOT of use.

That said I naturally always see ways to make things better. I have been trying to talk Haikelite into making a “TA” version of the MT09R to my specs but they have not really acknowledged it yet.

I think they are worried it would cost more and people would not want to pay the extra for it….

Thanks TA! As one of the unlucky one to have a non working light this is great to hear! Thanks for your efforts!

Thank you so much for all the work and information TA! A big thumbs up! :+1: :beer:

This is awesome news!

TA…can you comment on what the mode sets would be set as?

Thanks!

Thank you TA. Looks like I’ll get my light working.

The modes sets would be the standard Narsil mode sets with some minor tweaks. If someone has a suggestion for the modes let me know.

The mode sets is something I still need to work on, I never use them myself, I will not use anything but ramping for an e-switch light now day.

Also I didn’t mention it earlier but due to the heat issues the ramp will now stop before you reach 100% with double click turbo giving you the full power. Just like on the GT. By stepping down the power you can vastly reduce overheating and battery life with only a fairly minor effect on brightness.

This sounds very promising, thanks! Sorry for the dumb question, but does the new driver apply to both the 35 HI and 70.2 versions?

I second this question!
Especially for the 35 HI, what do you think about the possible lumens output for the 3 emitters? The 70.2 should easily achieve 15k lumens with your proper driver. (as it already has now)
