Just received a TS21 in RED w/sst20 4000K. It's awesome!
Has one strange issue - the BLUE switch LED comes on and off intermittently, on it's own, usually during usage. Funny I've seen the same exact behavior with the Astrolux EC06. Seems to be reproducible with the light cold, sitting for a while. Didn't check if the TS21 is using the same USB-C charging controller chip as the EC06 but I suspect it is. I believe Sofirn makes both the Astrolux EC06 and these Wurkkos lights. The BLUE LED is from the charging circuit. I get the same BLUE LED on if I connect for charging, then disconnect the BLUE LED stays on solid for a while -- strange behavior.
Wurkkos - can you guys verify this behavior? Anyone else see this?
Mine has the same behavior. The blue light will randomly come on after power off for maybe 30 seconds. I have the gun metal grey version 2. It’s an awesome light, my favorite actually. I’m wondering why it does this too?
It's designed this way, same as the EC06, same as the SC31 Pro - way too low resistor values used like 1K or 0.5K, when 6K-12K should be used. With the TS12, the amber at this intense level looks way too bright, but the low is very hard to notice - probably has to do with the mech design - poor placement, poor optics for the switch LED. I see other lights using a switch cover that's not very translucent - details, details...
