At the very simplest, oil lamps are just a wick or other source of flames submerged in oil or grease. While modern fixtures use a slightly more complicated process than this, they are still fairly simple machines overall. This means that these lamps do not need to waste a lot of space on their design and functionality to produce quality illumination. The result is a lamp that can dedicate more of its construction to style and elegance. There are also many miniature oil lamps as well, providing the same great lighting in a much smaller package. Because of their small size, they are highly popular as collectibles as well.
