About the Bulb black outline icon
A round light bulb switched on, surrounded by eight short rays that fan out evenly from the glass dome, with a ribbed screw base and a small filament loop at the bottom. The glow makes it read as an idea, insight or power that is active, so it suits tips and hints callouts, brainstorming and innovation slides, energy-saving pages, smart home lighting controls, and onboarding tutorials.
Rays and bulb share the same stroke weight, and the even radial spacing keeps the shape balanced in a square frame. The stacked base rings add texture without clutter. It pairs with lamp, battery, plug and gear icons. At small sizes the rays can merge with the glass, so give it extra padding in dense toolbars.
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.
