Q1:
No parastic drain has been detected. Will test it again in final product.
Q2:
The contact ring under the driver has been clamped, not be screwed-in. You will need a tool to pull it out by strong force if you want to dissassemble it.
No parasitic drain? You have electronic switch(es) right? So you should always have parasitic drain, unless it’s less than 1 microA and your DMM is not able to detect it…
Interested in the clamping ring of the driver. I’ll probably have a better look in the reviews… Thanks for the answers!
A lot of people here mod the lights, and therefore are interested in easy access to the leds and drivers. I’m interested in easy access primarily for possible repairs. If a driver is busted, then the manufacturer can just send me a new one and I can fix it myself. Otherwise I have to send the light (shipping cost), and it’s gone for several months… I find a construction that you can completely disassemble without (special) tools also very elegant.
Anyhow, easy access to components is something to consider as well when manufacturing flashlights.
I don’t mod. But it seems a lot of modders want more output. you can use just 1 of the 2 switches, and the mini version only has one switch. Maybe shave the domes. Change the emitters to high CRI XHP70. Who knows, maybe Vinh will put his own driver if possible…
Yes, this light has just one switch, but two switch's is not a problem. I'd go with Narsil/Attiny85/LDO/FET, maybe 1 7135, maybe a bank, maybe both - depending on the I/O pin availability.
