What happens is that the driver reboots. When the FET opens it lets current through, then when it closes it causes kind of a shockwave strong enough to reboot the MCU. So, in the strobe mode, for example, it’ll flash once or twice and then go directly to moon. Or it can go from turbo to moon, or one of the higher FET modes to moon, on its own.
Basically, if it runs at full power it reboots itself and goes to moon.
The attiny13a is tolerant enough to keep running regardless, even when it’s getting far more voltage than it’s spec’d for. But the attiny25v doesn’t respond well to these voltage spikes, and it reboots.
Newer driver designs eliminated the voltage spikes, but I don’t think banggood has any of those newer designs.
Thanks g_sintornillos ,
anything I should be aware before ordering? I see that many people were not satisfied with QC, mostly damaged emitters, leds with different tint etc!
I wanted to go for Nichia version.
First batch was for oblivion, high failure rate and DOA, then improved
I do not know what’s happening with the current batch, Astrolux is not characterized by having a minimum quality control, it can be a lottery
Mine, from second or third batch, bought at the end of 2016, works fine from out the box
Thanks, I wanted one for a long time but all this hiccups turned me off, hope they improved the light, wouldn’t like to get faulty nichia led, don’t have those at hand.
For those interested, I bought the Mateminco S01, which is the same as the S41S except they use the 5000k 219B emitters. The tint is better (less green) than my Astrolux S42 5000k 219c, and both MF01 with 5000k 219c. I asked the seller and they confirmed it is still the 219B. The quality is awesome. Very heavy in weight and good heat shedding from the copper. I hated the Astrolux S42 but I love the Mateminco S01. It has memory mode same as BLF A6 but its much brighter than the A6 from ceiling bounce test.
I don’t have an account there, but could you let the seller know they’re legally required to state that the product uses open-source code and provide a link to (or copy of) the source code?
Hmm.
$14.60 US works out to $27.69 AUD.
I ordered a Cree G3 to go with my Original 219B, 18650 tube.
I run that one at 4 or 5 out of the 7 settings. not more.
Gives good walkabout All over light. with decent range
and doesn’t heat up TOO much there.
With another coupla clicks for a few seconds to check something out.
We’ll see if the G3 gives a little more range hey.
