Sorry, I thought he said they would sell it.
They can say it’s not a flaw. How can you prove it’s a flaw? The light works as described. They never specified a run time using 7135 only. So calling it a flaw is just a persons opinion. It seems to be a common opinion and an add-on piece was made to make it better. So they are not under any obligation to send out a bunch of plates for free.
Of course they are not “obligated” to do it. And of course they won’t actually do it. They can say whatever they want.
I am talking about right and wrong, maybe you are aware of this concept? They messed up and sold a piece of junk, and it was up to members of the community to figure out what was wrong and to fix it … at not-inconsiderable expense. Now they copy that fix for new lights but do absolutely nothing for the thousands of customers who already bought it.
If they had any concept of right and wrong, any respect for the customer, or any pride in the quality of their work, they would send these heatsinks out to anybody who wanted one. But you are right, they won’t, because selling crap and not standing over it is the Chinese way.
I guess you should be looking at the cheap prices and compare to the big brands. Sometimes these things do happen, at least it wasn’t an expensive issue. Annoying yes, but for a cheap manufacturer to send out free parts is a big ask.
No such thing. It’s all subjective. Like you said, it’s a concept. Kind of like veganism. Is it right or wrong to eat meat? Different people have different ideas on the subject.
It is nice to see them trying to make improvements on their product, though.
You sound a bit racist when you say the “Chinese way” as if that whole group of people think the same way. You are on a slippery slope with that kind of talk. BLF is an international forum and we have members from all over the world. Let’s keep things civil.
Everybody who designs and manufactures a product, eventually has to test a prototype. To ensure all functions work, to write spec sheet etc. Immediately upon testing this, they will have realized there is a problem with premature stepdown. It is impossible that they did not realize it.
At this point they have two choices:
1) Investigate the problem and rectify it
2) Say “who cares” and ship the product anyway
When they choose #2 it means they have no respect for the customer, no pride in their workmanship. There is nothing subjective about that.
Your defense of this behavior is baffling.
I think the biggest issue is that they’ve been encouraged to use a firmware (anduril) they haven’t designed themselves, so the level of testing and knowledge of how it’s meant to behave is not the same.
Has there been a design flaw with models where they’ve used there own UI?
I like this light a lot. It has a lot of nice features. Compact, attractive design/look, multicolored aux leds that also double as a battery status indicator, rather high output, high CRI if you want it and USB charging. For what little i’ve used it, it worked well, but i haven’t pushed it much.
Sorry to ask but when or how does “the premature stepdown problem” arise?
I like to play devils advocate just to help people see both sides of a situation. Nothing personal.
It not when using Turbo or a low output, it’s when your using a med-high output where all the 7135 chips are going full blast. Like around the max ramp level (assuming the stock max ramp has not been changed).
The new mateminco MT07 comes with a brass heat sink,I contacted them on aliexpress. They provided an image, unfortunately i don’t know how to add an image to this post(clicked the image icon but doesn’t work, using an android phone)
You need to upload it to a hosting website and then copy and paste that link into this thread. More info here.
Does it look the same as the one Lexel posted?
I just picked one up two weeks ago from Banggood. Got it the other day. Still the version without the brass heat spreader. Hope they sell it as an extra part one day.
//Does it look the same as the one Lexel posted?//
Yes its the same 
Are all of these lights supposed to come with AUX LEDs in the lens? I just received mine from Banggood and I think they may be dead. I do see the four pots under the lens but turning them in either direction does nothing. A few of them even spin indefinitely.
Did you turn them on in the software?
With the light off, do 7 fast clicks. ( I think that is the correct procedure. Someone correct me if I’m wrong)
Yes they have multi colored aux leds under the optic. As said, 7 clicks from off will set them low, high or off. They should be active by default though. You should not have to touch the small pots unless you want to increase or decrease some color brightness. This is fine tuning only.
Yes, that is the correct procedure. I clicked 7 times for multiple cycles and the only thing that changed was the light in the switch.
It’s possible that one of the three small wires going to the auxiliary LEDs may have came loose during shipping. If you have a digital multimeter you can verify that there is voltage across the small red wire and small black wire. That should be battery voltage. If you’re not getting a reading then one of those two may be disconnected. If you get battery voltage then there’s a small chance the blue wire is disconnected. You could probably pull on it with tweezers very lightly to see if it feels completely loose or if it’s connected.
Anything beyond a loose wire my indicate that there’s something defective with your auxiliary LED board.
I’ll have to check if my multimeter still works. If it does happen to be a loose wire would soldering be the next course of action?
