Hmmm, maybe! Dinotte says its 2020 "Quad RED replaces the DiNotte 300R and 400R...The Quad RED is as bright as the 400R lights and significantly brighter than the older 300R, the older 140R lights and the Quad RED lights manufactured before 2017." In turn, they say their 400R - I think no longer a current offering - was rated at 300 lumens, while their "daytime red" - ditto - was 400+ lumens.
If the Cygolite Hypershot 350 is similarly bright, yay! It's certainly more affordable. And it looks like the Cygolite uses a "hard seatpost mount", which I hope makes it more likely to stay pointed in the right direction. Dinotte has always had good mounts, whereas many/most other rear lights don't.
I remain a dedicated Dinotte customer. As others have also reported, drivers - including cops - comment regularly to thank me for using my Dinotte rear lights. And they're MUSA, and repairable/rebuildable.
