How does 90 lumens qualify as powerful? It’s not lame, but certainly not great light output.

Probably bright enough, I’ve seen rear bike lights that are so bright they leave an after image and are actually distracting after dark. Anyway, you can always add a second, brighter light to the bike or back of your helmet, for extra visibility.
I had a rear light that had a brake-light function many years ago on my Cannondale SuperVee 3000, it worked off a mechanical linkage to my rear V-Brake, and was surprisingly effective at getting drivers to back off as I was braking for red traffic lights, or slowing for corners.
I haven’t ridden any of my bikes for some years due to a knee injury, but I’m all over this if I get back to riding again.

Or you can skip the extraneous frippery and e-waste of connecting it to your phone for $7…

A 90-lumen flamethrower is pretty weak. Also, not the best option when biking on a hot summer day.
0/5 stars, would not recommend.
I got this german made helmet that had a rear light in the back but there seems to be no way to change the battery
