I have a good number of Aladdin oil lamps along with some Dietz outdoor lamps and regular oil lamps. These work fantastic indoors or out, the Aladdin's are especially bright because they not only have a round wick but a mantel also. The lamps produce about 100 watt light bulb worth of lumen's. I burn a 99% paraffin oil that is virtually odor and soot free, and keep quite a bit of kerosene on hand also. Also have a ready supply of wicks, mantels, and chimneys. Also have propane lamps and battery style lamps, I keep an adaptor for the propane ones so I may use a 5gal bottle if necessary. Remember not to put all your eggs in one basket. You can see in one photo the one I have mounted on the kitchen cabinets.What's the advantage of an oil lantern versus a battery-powered lantern? Are oil lanterns safe to use inside?
Yes, and also IMO you won't be wanting to light the whole place up like some people do now-a-days,post SHTF. Oil lamps do well for spot/task lighting,which is what most of us will be needing then. We'll be doing everything we can during the daylight hours and will probably be too tired to be staying up all night for silly reasons. People's schedules will change dramatically then. Lights will be needed more than likely for a couple of hours in the very early morning ( for tending the animals,cooking,etc) and then for the same reasons in the evenings after dark.The greater the variety you have the more flexible you will be. The object of lighting is to be able to do things later in the day after sunset.
