Well, I have not read the publicity for glow-rings and don't know if it's one of the recommanded usage, but I would never think using one to read or find my way in the dark. That can be done with Krill lights or chem- lights.

But IMHO glowrings are nice to attach to something you want to find in the dark, as you described in your post (finding a flashlight etc ...).
