I've used this light for two years and it's been perfect. It's super bright and sturdy, requiring a charge once or twice a week.
Just noticed it went on sale, down from $259 to $149 (+$10 for MTB mount). Also comes with an extra battery pack and a spare battery as part of the clearance. Unfortunately the $30 antiglare bezel is sold out, but I think it's reasonably easy to 3D print a hood.
You can also get a spare 26700 or 26650 battery on Aliexpress pretty cheaply.
These guys are from Adelaide and originally started on Kickstarter, but it seems like they're shutting up the shop now (social media pages are haven't been updated). I was actually looking forward to getting some of their smaller variants ("coming soon") for occasional use in early mornings.
That's a lot of money for a bike light…
