Jetbeam sold me a spare part for a different light. All it took was to email them (info at jetbeamlight.com) and to pay the invoice. My contact was very knowledgeable.
If the new battery tube fits the old 2019 head, I’ll order it.
I wonder if the slots around the tail cap on 2020 version are large enough for tritium vials. Interesting light as I’d the switch. Did the older models offer Nichia 219C as well as this one?

no one has the 2020 model in hand yet, so we dont know the size of the lanyard slots… to my eye, they look larger than a 1.5 x 6mm tritium, pure speculation…
the 2020 is the first to offer 219c, and tailswitch
Wish I had one. Really not happy I couldn’t get one at an (to me) affordable price. Guess this won’t change anytime soon. Fingers crossed the 2020 is somewhere between both in dia.
That said, I highly doubt there is a secondary inner tube contact to the tailcap like in an FW3A…. which means the tailcap switch is likely not electronic and can’t control the driver in the head of the light.
My guess is the tailcap switch is a simple forward clicks like in a Sunwayman V11r. The ring lets you set the brightness before using the switch to turn the light on or off.
If they use a forward clicky the light should also have momentary available in all modes.
Rotary with tail switch (and stock option for a very decent emitter) puts this in much closer competition with the HDS Rotary, at least interface-wise.
Considering this is now only one of two lights I’m aware of with fine/continuous output selection from off with a tail-switch for activation that makes the price fairy attractive.
The size/weight for each battery format is competitive also, with the added benefit of much higher output than an HDS.
