Lightbulb Fill

The lightbulb-fill icon represents a filled lightbulb, symbolizing a bright idea or inspiration. It is often used to represent creativity, innovation, and intellectual pursuits. The filled style gives it a more prominent and attention-grabbing appearance.

In software and digital design, the filled lightbulb icon is often used to represent a significant idea or a major breakthrough. It can be found in various applications, such as brainstorming tools, design software, and educational platforms.

From a UX perspective, the filled lightbulb icon communicates a stronger sense of insight or understanding. It helps users understand that they are in a space where they can explore and develop their ideas.

Lightbulb Fill is one of 9,161 icons in Phosphor, made by Phosphor Icons and released under MIT. It is drawn on a 256 × 256 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds LightbulbFillIcon to components/icons/ph-lightbulb-fill.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed LightbulbFillIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Yes, if your project has @phosphor-icons/react: Lightbulb Fill is `Lightbulb` there, used as <Lightbulb weight="fill" />. The shadcn.io MCP server answers with that import when it finds the package. Without it, copy the icon from here.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Lightbulb Fill icon, or any of 9,161 Phosphor icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 256 × 256 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Lightbulb Fill", so screen readers say what it does.

Yes. LightbulbFillIcon passes every SVG prop to the svg element, so <LightbulbFillIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes. MIT allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: MIT only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Phosphor, Phosphor Icons and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
