So five candles, that's what we have now
and if you want to see across
it's difficult. If I'm on the other side of the room, I can't see anymore.
And these candles can go out so quickly, like that.
How long does a candle last?
About half an hour.
Twenty minutes.
Remember, the kits last five hours.
If you charge it during the day, it will last five hours through the night.
Remember this level of light.
Look around at everyone's faces
and how they look.
Okay, now I'm going to blow out the candles.
Ready?
1,2,3...
Now that's a
big difference, no?
Now I can see the tortillas.
You didn't notice them there before, right?
Now any person in any part of the room
can be working.
Here you see these long cables
"Ten meters." You could put another lightbulb there in the corner, and now the room
is perfectly lit.
