Bulbs are a source of light, and are often used to denote bright ideas! In this set, we bring you not one or two, but ten variations of these bulbs. These bulb graphics can be used on their own, or also combined with other graphics such as a human head to create a larger concept or analogy! Each individual shape is a native PowerPoint shape that can be re-sized, rotated, or moved as required. You can also animate individual shapes as required. You can even change fills, lines, and effects or even apply Shape Styles.
