RE: understanding light
As preppers all we need to know is we need light to see, plants need light to grow and the light required for those is slightly different so a light bulb is great for seeing things but not so good for the plants, you need a special light. Sunlight has a wide spectrum and covers both. Sunlight is good, artificial light uses power and isn't as good.
Darkness is your friends when you are a predator and your enemy if you are the prey.
