About the Lightbulb black filled 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 solid black filled version of the lightbulb icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
