Outline light bulb with filament and screw base inside a circle
About the Lightbulb black filled icon
A light bulb inside a circular frame, shown with a rounded glass envelope, a small highlight arc, a filament loop on two support posts and a ribbed screw base. It is the standard shorthand for ideas, tips and innovation, fitting blog callouts, brainstorming boards, product feature lists, energy saving pages and pitch deck slides.
The bulb fills most of the ring with even margins, and the interior filament keeps it from reading as a plain dome. It pairs with rocket, gear and target icons for a startup set. The base ribs merge below 20 px, so scale up for print.
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.
