Survive a Power Outage: Emergency Lighting
Emergency Lighting explains light, where it comes from and how to measure it. Then it covers all the sources of light: candles, firelight, flashlights, lanterns, and solar light from the sun. The book explains how to determine how much light you need, what kind of lighting is best, and how long those batteries will last in an emergency. Charts, tables, and photos provide personal options for you.
