If you're not after a road specific beam (the exposure race doesn't seem to be), I would look into getting a 21700 battery based flashlight. You'll get the latest tech, customisable firmware like Anduril, it'll be way cheaper and you can just take a spare 21700 cell to double the battery life. Paired with a gopro based 25mm mount like this: https://76projects.com/collections/shop-computer-mounts-light-brackets/products/gopro-style-light-brackets?variant=41912009130171.
Something like the Sofirn IF25A might work, which seems crazy cheap at the mo: https://sofirnlight.myshoplaza.com/products/sofirn-if25a-anduril-2-rechargeable-flashlight-max-3800-lumen-with-sst20-led-and-typec-charger?spm=..flashsaleCollection.flashsale_1.2&spm_prev=..collection.header_1.1
But you'll need to do some research to find the right one for your lumens/battery life/beam requirements. On this thread, someone put a exposure mount on a big Sofirn: https://www.mtbr.com/threads/sofirn-sp36-for-bar-light.1178014/
I'm trying out one of these at the moment: https://lumintop.com/product/b01/. It has a STVZO like beam for the road and can even be powered from a powerbank.
