If they changed to a lower CRI and is proven in testing they will take a big hit on their reputations as a brand. So I donāt think they would cheap out. Itās too big or the risks. If they raised the price (which they did) and cheap out on us I would never buy their their product again if that happens. And it doesnāt take long for people to find outā¦.
Just courious why Banggood/Astrolux donāt specify this on the site. Bit short on trust these days and published specs leave a lot of leeway. Will wait until someone can confirm that these second batch are 90+ CRI 219Cās as well. One light shipped to a known excellent reviewer does not a whole production make.
Does anyone know what percentage of Astrolux MF-01 has had bugs? Iām talking about the first batch, of course. And what mistakes have they been? What has been the most repeated failure?
It was 3P-2S3P, so 6V for the two leds in series, with 8.4V input voltage.
Now theyāre saying theyāre changing to 3P6S? You need a different (boost) driver or not?
How uneven does it need to be in order to qualify for a replacement? I do love my MF-01 and will be ordering a second one in the next few days, and the differences between the brightness levels arenāt as pronounced as what Iāve seen with some others. But the problem seems to have got slightly worse over time, and Iām worried that this fault might turn into something more severe, especially as I like using my lights as candles.
Since Iāll be having a backup fairly soon, I donāt mind sending back the head for one that works correctly. What should I do - get in touch with BG CS?
Iām trying to figure out the same thing. I would have already sent mine back if Iād had been asked. At this rate, itāll be mid-November or even December before this is resolved. :person_facepalming:

So it looks like Banggood shipped from their EU (UK) warehouse, I might even get it in a couple of days
If indeed changed to banks of 6 LEDS in series, with a boost converter (or one converter per bank), that could be very interesting.
If well regulated it could be superior to the existing buck converters (running 2S LEDs from 2S cells), once battery voltage drops. Less loss in LED wiring and MCPCB traces too.
If it was down to me, Iād also arrange one bank to be the inner circle of 6 LEDs, and switch off the other two banks at lower levels. That would eliminate problems of uneven illumination of banks, and allow finer control of lower light levels.
Fingers crossed for something along these lines, rather than just a minor tweak. Should soon know.
