How to illuminate a lantern

I picked up a few iron lanterns similar to THIS for $10 the other day. About 10-12" tall, 6" wide. (My glass is white frosted, not yellow like in the photo) I was wondering what youi guys have for suggestions in lighting it. Just use a standard bulb?

How about flame. You guys have any suggestions for lighting that simulates that?

Also anyone ever try the “flame” bulbs from Lowes? They aren’t the orange neon bulbs, they’re frosted white like an appliance bulb but claim to be like a candle or sumptin.
