A power outage is more than an inconvenience; it creates immediate physical dangers from accidents and falls, worsens fear and morale and leaves you unable to perform essential tasks. Candles and oil lamps are serious fire and safety hazards, provide poor light and can compromise air quality. While modern LED flashlights are bright, relying on disposable batteries is unsustainable for a long outage. Batteries expire, are expensive to stockpile and leave you in the dark once depleted.
