I’ve never seen a certification document for a flashlight. I sold some 8 year old Convoys, i wonder if they had been tested/certified.
How did you figure out that Astrolux/Mateminco refuse to test?
I was a dealer for them and asked for the certs of their new models. Ben, who handles all customer service, said they no longer carry out any testing.
This is slightly concerning that they simply don’t care anymore to make sure their products are safe. Banggood is really their only buyer for the Astrolux brand, so there’s no need in their eyes. If they had a large number of dealers worldwide it would be different.
That’s not how you choose a battery though. You need to understand that most drivers rely on a battery’s voltage for outputting the highest possible lumens. When you apply 9.8A on the Samsung 50E the voltage will sag on load thus reducing the lumens.
In my opinion, if a torch requires up to 10A I’ll recommend a 15A+ battery. For my Osram 5A builds I’ll bundle a 10A battery, for 10A I’ll bundle a 20A etc. You’ll get longer runtime off a battery if it’s not pushed to its max rating
A battery’s capacity rating is measured at 0.2C (0.2 X capacity) discharge current. You’ll get less capacity the higher amp load you run the battery at
A Molicel P42A and Samsung 40T may achieve longer runtime than a 50E
I meant if the 50E is driven hard, but that doesn’t really happen in a flashlight I think, it only delivers what it’s capable of. Someone else might know a bit more about that.
Looks like the 50E would still provide higher capacity anyway, so the above does apply in this case.
At 10A the 50E still gets 4,750mAh and the Molicel 3,900mAh ish. At 20A+ is where you’d see the Molicel shine.
A pressure buildup inside of a flashlight is entirely different than a battery explosion. Unless I’m missing something I don’t think we have evidence of batteries exploding in flashlights. Yes there is evidence of flashlights “exploding” from internal pressure. Mostly out of the ends not the barrel itself. Always point your flashlight down range. Just say no to 123s.
