1st off everyone has a key chain light and somekind of flashlight next to the bed. We have Sears/Craftsman re-chargable Ultra Beam flashlights, they are like a 6 volt flashlight. We also have 2 older re-chargable lanterns.
Plenty of batteries and a solar panel. I've been getting away from Chem lights for most things and going with LED Light Sticks. They come in Red, white, Green, Blue & Amber.
www.rangerjoe.com has them $7.50 for a pack of three, same color. Batteries $1.00 for pack of three needed for each light. Found I just wasn't using the Chem Lights except at Halloween when they expired. Item # 8800 for lights and # 8865 for batts, haven't seen them other places. Last resort is storm candles. Be carefull with candles, I believe that the Red Cross no longer recomends them because of fire danger.
