I lived off the grid when I was in the ninth grade, and all we had for light was a kerosene lamp that put out about as much light as a pretty strong candle. It was hung up reasonably high, and so wasn't enough to read by, and, regardless, I slept up in the loft with my brother - and so the light didn't get up there (thought it did make for a nice warm spot on the plywood floor). When it got dark - we went to sleep. And then we got up at 6:45sh to go catch the bus to school. I don't ever recall a "second sleep" or waking up after I fell asleep. Maybe this doesn't apply to teenagers.
