[DC]Why does the Green Power Battery look like a primitive light source whose unique design was only used on earth for like a century?

Because the earth lanterns you are referring to were also developed by other races at other times.  They represent a design which was independently developed many times throughout the universe.  They were a successful design because it performs a needed function (providing directional light) using a wide range of power sources and portability.
