FAQ
Answered from lambda's own facts: its shelf, the weights it was drawn in, its siblings and its dates.
- What is the lambda icon for?
- The lambda sign, for anonymous functions, serverless jobs and wavelength. It is filed under Math in Keyline Icons, drawn on the same 24×24 grid as the rest of the set. People look for it as anonymous function, serverless, wavelength, greek, half life and function, and the browser's search matches all of those.
- What styles does the lambda icon come in?
- All four: stroke, two-tone, duotone and fill. They are drawn from the same geometry, so swapping style never moves anything.
- Is there a square or circle version of lambda?
- No. lambda is drawn as a bare glyph, and the set has no boxed variant of it.
- What other icons go with lambda?
- angle, asterisk, brace-left, brace-right, braces and braces-ellipsis, and 12 more, all shown below. They are the Math shelf: nothing else in the set is named after lambda.
- How do I import lambda in React?
- <Lambda /> is the component, and the weight decides the module: stroke from "@keyline-icons/react", two-tone from "@keyline-icons/react/two-tone", duotone from "@keyline-icons/react/duotone" and fill from "@keyline-icons/react/fill". It takes the usual SVG props plus a size, so <Lambda size={16} /> and className="size-4" both work, and there is no provider or theme to set up.
- Where is the lambda SVG?
- icons/stroke/lambda.svg, icons/two-tone/lambda.svg, icons/duotone/lambda.svg and icons/fill/lambda.svg in the repository, normalised: no wrapper, no ids and no classes to strip out. The tabs above hand you the same drawing as SVG or JSX without the download, and neither needs an install.
- When was lambda added to the set?
- Added 20 Oct 2026. It ships in v2.1.0, so an install at that version or later has it.
Questions about the set rather than about this drawing are answered where they belong. The home page covers what the set is, how the three styles differ, why some icons come boxed and where the Figma file is; installing the set in a shadcn/ui project covers the React package, the CLI and using an icon without React. The MIT licence is stated in the footer of every page.
