In our church we are always reminded and taught how to store food. Just this morning I attended a food storage class in our church. After the class, I get more interested in storing food and preparing things we need in case of emergency like emergency light. I think it's a good idea to have an emergency light at home. I would like to have one when we get our own house. Exitsignwarehouse has really good deals on emergency light. I checked the prices and they are very affordable. They sell other stuff too.
