My new TK R5 emitter is glowing,ever so slighty,long after using the light. If I unscrew the tailcap the emitter stops glowing but when I tighten the tailcap again the slight glow returns. What gives?
That's the problem with some Fenix multi-mode lights. It also happens on the LD20 Q5.
Try disassembling the tailcap, clean it and screw it on tight.
Unfortunately, they put thread-lock one some of the tailcaps, I couldn't take apart the one of my LD20 to install an orange rubber boot and the one of the PD20 was tough. It's their secret, why they give you a spare boot with the light.
Clean everything you can without voiding the warranty and if the glowing continues, send it back!
Modern leds produce light at extremely low currents.
What you see is most likely just an output capacitor of the driver discharging. They are small, but when the voltage drops, its a very high resistance discharge through the led. For some AC drivers that have nice big caps, the glow can last for a minute or longer.
There is nothing wrong with it.
So .... you're saying the 2 slivers of aluminum inside the switch were causing a high resistance circuit , causing the glow ?
And it's fixed now ?
