The mark consists of an incandescent light bulb in gray with silver screw threads that is stylized to look like a globe with the continents in green and a small, round shadow underneath the light bulb. The image is interrupted by a horizontal banner with the entity name, EDISON LIGHTING SUPPLY, in all capital, black lettering with the word "EDISON" approximately four times the size of the words "LIGHTING SUPPLY". The words "LIGHTING SUPPLY" have an elongated, green hyphen before the "L" and after the "Y". At the bottom of the image, adjacent below the shadow, are the words "Saving you energy dollars one socket at a time." in green lettering that is approximately one half the size of the words "LIGHTING SUPPLY". This slogan "Saving you energy dollars one socket at a time." is in the form of a proper sentence with the first letter of the first word, "S", capitalized and ends with a period.
