Outline light bulb glowing with rays around it and a ridged screw base
About the Lightbulb black outline icon
A pear-shaped bulb sits inside eight short rays that burst outward, while three stacked bars form the ridged screw base. The drawing reads instantly as an idea, a hint or a moment of insight. Use it for tips panels, brainstorming and innovation slides, help centers, energy-saving pages, and feature callouts in product onboarding.
Strokes are even and rounded, and the rays are spaced evenly around the upper glass so the shape stays balanced at small sizes. It pairs with lamp, plug and battery icons from the same set. Keep it at 24 px or larger so the three base lines stay separate.
This is the black outline version of the lightbulb icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
