Idea of Illumination Icon
It's a logo of Edison Bulb reduced to an image of a basic light bulb. It looks like an ordinary light bulb but has a classic look to it. The Edison Bulb is one of the first bulbs created.
This is a Illumination icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,900 icons, all in the same style and quality.
