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 don’t think they would cheap out. It’s 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 doesn’t take long for people to find out….
Just courious why Banggood/Astrolux don’t 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 219C’s 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? I’m 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 they’re saying they’re 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 aren’t as pronounced as what I’ve seen with some others. But the problem seems to have got slightly worse over time, and I’m worried that this fault might turn into something more severe, especially as I like using my lights as candles.
Since I’ll be having a backup fairly soon, I don’t mind sending back the head for one that works correctly. What should I do - get in touch with BG CS?
I’m trying to figure out the same thing. I would have already sent mine back if I’d had been asked. At this rate, it’ll 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, I’d 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.
Guess mine counts as extremely ‘uneven brightness’ - one bank always 100%, can’t be turned off at all (have to unscrew the tail or head).
By the way, Chinese holidays ended already? because I still don’t have any response from BG. And after that, it will be waiting for the light to be shipped back, then shipped again to me…
disappointing a little.
