We use these at night. Nice and dim, warm, low flicker, and also very affordable. You'll just need an adapter for most lamp sockets.

For dimmable LED options, The Bedtime Bulb and this GE vintage bulb are the best I've found. They will need to be dimmed though s they're a bit too bright for night use in my opinion. Especially the Bedtime Bulb (even the candela version)
