What does this mean? A single 18650 with 10 Wh can power 0.002 W continuously over 6 months. More than enough power to see light. But what would the point be? It is useless at that brightness.
It easily lights up the corner of my room on the beside table where I keep it in case I lose power. You can read by it with good eyes in a dark enough room.
What happens if you lose power after it's dead from being on for 6 months?
I recharge it for a few hours twice a year and use one of dozen other lights in its place.
