It fits your requests for:

I can turn off the display completely — this saves my sleep so much.
I set a 30 m light to gradually go off. So I read in her on an actual book and when I can’t see to read anymore, I bookmark and set it out. Feels so much better than looking at my phone to sleep.
I set a 10 m wake up light that goes before my alarm. So, sometimes it’s a more gentle way to wake up. The actual alarm will go if I sleep through that. Fine, need to get up then.
