During the late 1800's, around the beginning of the
use of electric incandescent lighting, the Gas and
Electric Chandelier is also called transitional
combination and G & E form . This chandelier style
was derived by the use of incandescent lighting
added to the earlier gas chandelier form. Typically
for example on a 6 arm gas and electric chandelier
you will see the 3 gas arms facing up and the
3 incandescent lighting arms facing down.
This is commonly called the combination form.
