A GLOBE is

Earth: the planet Earth

A BULB is
|1.||underground plant part: an underground plant storage organ, e.g. a corm, tuber, or rhizome, from which a new plant grows every year|
|2.||plant growing from bulb: a plant that develops from a bulb or other underground storage organ, e.g. a tulip or crocus|

It is suprising that some people still refer to electricity/ light bulb as a globe!
This is wrong. The two words are different.
