The mark consists of a lightbulb with a gear and a stylized e in the center of the bulb. The bulb is dark blue color that surrounds the gear and the stylized e. The gear and stylized e are transparent and will show any background it is placed upon through the negative space. Below the bulb you have three lines that look like they are the lightbulb's screws. The top line is teal. The middle line is the same dark blue color as the bulb. The last line is shorter than the first two, and is the same teal color as the top line.
