By the way, on my substrate is not copper, brass, although 2mm thick. In general, I do not like SST 5000K in this optics. I will put XHP50.2 3000K. Only now I think: to dedomite or not?

Is the xhp50 3000k 6v or no? Are you planning on a new driver?

What is substrate? The XHP50.2 3V does not come in 3000K, so is it a 6V LED?

Yes, it’s 2mm, but I’m pretty sure it’s red copper in mine. I polished it to make it smoother. Unfortunately, there is no 3V XHP50.2 warmer than 5000K. At present, it is currently only available around 6000K.
I’d like to see with CULPM1.TG.

I have brass. I can take a picture, but you can take my word for it. I had something to do with metalworking.

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?

The photo is not very good, but I think it’s clear: what is it …

Yep, the pink sides looks like copper to me. The bottom is oxidized copper - it cleans up with some sanding.

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:

XHP50.2 LEDs
Look at the chart on page 5.
The store you linked to probably uploaded the product wrong.

Red copper is such color. The picture shows a raw PCB below it.

I can understand the confusion - no problem, good you got it settled.

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.

Somewhere on this site I read that maybe the AMC7135 is causing the high parasitic drain. I removed it and still have high consumption.

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.

What about the charging circuit?

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.

Just don’t use Turbo. You could always use higher gauge wire from the driver to the LED to limit the current.

The donut is present because the beam hasn’t formed properly.

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.

I believe that would be the Manker MC13.
