Most ceiling fixtures have a couple bulbs. Get one with three, and a bedside table + lamp on each side of the bed. That’s at least five hue bulbs, which lights up a room very effectively. Not full sunlight, but enough.

I think you aren’t including in your calcs that you’re presumably not in a black room. A light colored paint means the light that isn’t going straight to your eyes from the bulb still brightens the room significantly.
