Sofirn has sent some more lights to AmazonAU warehouses, and have given me a code for a discount on it to share. This time it's for the SP33v3; this particular light is in a kit with USB cable and battery, so after charging, you're ready to go.
Disclaimer as per usual: I’m not technically affiliated with Sofirn, but have had dealings with them in the past by reviewing some of their lights - I've posted codes before for them, and that seemed to go well, so they've given me yet another code for AU stock.
The UI has two modes - either stepped or ramping. Stepped, hold from off for the lowest mode, then you hold the button when on to rotate upwards through the modes with a double-press for turbo; ramping mode you hold the button to get brighter/dimmer; this goes all the way from the lowest mode to highest.
If you've read this far, or just decided to jump down, then the link and code is:
SP33v3 kit ($58.99 $50.14): Z228VKYH
Ooh, tempting but would rather stay with AA and 18650 form-factors for now.
