Are you talking about the MCPCB??? Don't know why you are not answering my questions.
If so, from 2012, I've never seen or heard of a brass MCPCB - ever. It's thermal conductivity is worse than aluminum, it would be a mistake and tragedy, to say the least.
Some copper MCPCB's, like Hank's Noctigons, have gold plating on the bottom that has the same color as brass - maybe that's why?
Yes, you are right, I polished it and everything fell into place. But you can also see why I was wrong. The color of the patina is exactly the same as that of brass. Compare the brushed side with the edge color and the other copper base color:
Yes, I myself am glad that this is not so. I would not like to think about such a ridiculous substitution. Such powerful lanterns will burn like candles. Reputation worries should outweigh petty gains.
I received my EA01 replacement head and the parasitic drain is lower now, about 50 microamps. It also seems brighter than the first head for some reason.
Charging circuit checked out also. I saw 1.8 ish amps and stopped at about 4.18v. I forgot to mention that the parasitic drain was measured with the switch led on low.
I installed in my Osram KW CSLPM1.TG 5P 5400K.The shape of the beam is a bit similar to the SST-40, but without the wacky color changes depending on the voltage.And thank God without greenery on the bottom ... Saturn's rings are still present, at distances of up to 30cm there is a distinct donut.The battery I use is 26350 6A.With a turbo, even on Litokale 5000 (26650), a clear overload of the diode is visible (it turns blue).So: either not to use the turbo, or it is better not to risk it.
Пончик присутствует практически во всех дальнобойниках, с подсветкой до полуметра. Я уже говорил об использовании турбо. В варианте 26350 он чуть выше старшего режима, и никакого вреда или перегрева не наблюдается ...
У меня есть VapCell 26350. With some kind of higher current I would not use a flashlight ...
Но мне нравится свет, и мне нравится производительность. Гонял вчера на разных режимах всю прогулку. В том числе и долгий турбо на разогрев. И после всего этого у меня осталось около 4В ...
I really like the larger TIR optics used like the EA01. I have the little 18350 body tube and it pumps out some light for such a little flashlight. Im on the hunt for something similar to the EA01 that uses a SBT90.2 with a big TIR, I reckon that would be nice. I think Manker makes something like this but not sure which model.
Only way that would be according to the art rules that I can think about is designing your own 6v driver in this case. Actually this could get some attention from blf as some other Mateminco/Astrolux lights use the same driver.
However if you would like to mod current one in theory zener mod could be tried, but I don’t know if this would affect charging circuit or not.
Zener mod is also harsh for AMC and you may end up burning it at 6v. On the other hand you can remove AMC and get FET only driver, but that would require MCU program change to use only 1 channel.
