Lamp doesn't act as a light source?

[dvow]

Darkness drains sanity. Light does not regain it. Making progress is the only way to regain it, at least according to the developers.

It'd be lame if you could just chill out by a light for a few minutes and be in tip-top shape.

Kicking back beside a light source does regain sanity actually. On my first play through, I was overly concerned about my sanity, and would often find myself chilling under a light source until I regained some sanity. It always worked. I never went to full sanity though. Light only seems to regain a certain amount. I also noticed that the natural white light from outside sources regains sanity faster than candlelight? Can anyone else confirm?
