About the Bulb black outline icon
A classic pear-shaped bulb with a ribbed screw cap below it is surrounded by eight short rays spreading in all directions to show that it is lit. It carries the meaning of ideas, insight, tips and innovation as readily as literal lighting, so it works for hint and tooltip buttons, brainstorming and startup slides, energy saving campaigns, smart home light controls and electrical product listings.
The glass dome is almost circular, the contact base is drawn as three stacked bands, and the surrounding rays are evenly spaced at equal length, which keeps the icon radially balanced. It pairs with gear, rocket and target icons in the same idea set. Drop the rays when placing it inside a dense toolbar to reduce visual noise.
This is the black outline version of the bulb icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
