STVZO is very prescriptive, it's not just the beam pattern, you can't have, even on a switch, a high beam or flashing mode either. Both of which the magicshine has.
Same with rear lights, the STVZO standard says the light must have a constant red light and a built in reflector, nothing else.
Club run is tomorrow night so I'll put up some comparison shots against my Lumenator which is IIRC 1800 lumens so on paper would be a good comparison. But suffice to say I'm pretty impressed with it. The dipped beam is very well shaped, and quite a bit wider than some stvzo lights I've tried. It's very good. The "main" beam I'm reserving judgment on, it seems like it almost mirrors the dipped beam upwards, so you've still got a noticeably flat beam, we'll see how that works out on some fast descents with corners. The remote switch / app / button is a bit confusing at first, it sounds complicated but in the real world 'square' takes you straight to full power main beam, and circle takes you to the previous setting, so for probably 99% of people that will be dipped on mid or high power I guess. If you double click circle it switches from dipped to main, and a single click cycles through low/mid/high in whichever beam you're in.
Like most lights it's fault is offering too many modes. Just give me the ones I'll actually use on the light, and maybe hide the rest in the app. 99% of the time I probably just want full main beams and a full dipped beam. The only time I'd want anything else is would be an overnight audax type ride and then I'd have to choose between either a low/medium beam or running on external power. And on that note, it can run on external power (as long as it's dry) form any USB-C cable and a power bank.
Will check out the magicshine light above and a few other brands that have light to GoPro type options.
Dunno if I missed it on the magicshine literature, but the 1700 EVO has a go-pro adapter, but the light itself slides on and off a mount. You press that textured bit under the clamp to release it and the lamp body slides back off it.

I've got the Magicshine 1700 light on a cheap Amazon metal out front stem mount. The original supplied bar mount is plastic and felt like it might break. I've had it a year now and its been a neat solution without cluttering up my bars. The light has been very effective on the road and down bridleways. Not sure on its claimed lumens, but it's plenty enough for what I've used it for in the pitch black.
I don't use the quick release button to release the light from the clamp, but instead use a GoPro thumb bolt instead. The app is abit flaky at times connecting but the remote is great.
I also like the fact I can run a battery externally to keep it going (albeit in dry conditions (unless there is a way you can knock something up to protect the charge lead from water ingress).

Interesting comments on your Magicshine 1700 EVO. Mine just arrived from the Magicshine UK store based in Bodmin and I have 3 issues:
1) the GoPro connector between the Out Front mount and the light itself was a swine to get together and took a chunk out of my finger in the process. The connection is so stuff there is no way the light can ever be tilted (doubt I'll get it apart again) and the tightening fixing bolt is pointless. The nut bit does not fit well even with the holes lined up correctly.
2) I was unable to download the Magicshine App from the Google Play Store as I get the following message

The phone is an 18month old mid-range Samsung with up to date software.
3) I was surprised to note in the very basic paper instructions (yep, I should have checked before buying) that you only get 5hrs in daylight flash mode. Which is pretty poor/pointless.
I have asked the UK Magicshine store for a return, though it is annoying as I can see myself paying for 2 lots of postage, to me and the return as well.
Thoughts please ..
The message on your screenshot says your device is too new rather than the other way around.
Doesn't help though I know.
OK, though I interpreted it as 'an older version of Android' meaning the Android (14) operating system on my phone was too new for the Magicshine App to work with.
Whichever Magicshine UK have said I'm not the first with this problem.
nick- your problem with the go pro mount may be down to the prongs of the out front mount being a little too tight rather than those of the adapter. I only say this as I have two evo 1700s and have switched them between a few different bikes/mounts. Neither of mine were so tight I struggled to fit the adapter but did have the opposite issue with one of my mounts (an aluminium out front mount) in that it needs the gopro screw to be done up super tight (ie. screwdriver required) so that the bracket can't easily rotate. I ride on the road at night a lot so always use the quick release feature to remove the light from the bike for charging and want the bracket secured tightly enough that it won't rotate when re-fitting the light.
Secondly. the Magicshine app is absolutely terrible. I completely ignore it now. Set the lights manually to my preferred brightness and then just use the remote to switch between dip and main. It's quite unlikely I'd ever need to change brightness on a ride. I run mine on full but as I'm on roads it's generally dipped for all but faster descents. Haven't ever run out of juice and I regularly use one for 3hr solo night road rides. When angled optimally the dipped beam with it's very defined cut off line really is great for road use. I'd try the light to see how you get on with it riding before giving up and sending it back.
Great little lights . Shame the App is so poor. If it's any consolation the App for their rear SeemeeDV rear cam/light is even worse. Instructions are quite poor too.
Whoever mentioned charging in use. have you thought about making a thru cover for the usb port from Sugru? I've done this successfully in the past with other lights.
