About the Spiral CFL Light Bulb black outline icon
An energy-saving lamp built from a long glass tube coiled into a tight spiral, stepping down to a ribbed neck and a threaded screw cap. Unlike the classic pear-shaped bulb, this shape says efficiency, lower power use and modern lighting. Use it in utility and energy dashboards, sustainability reports, home improvement stores, electrical supply catalogs and eco campaign slides.
Five parallel coils fill the upper two-thirds, balanced by a compact base below, so the icon stays vertical and stable in a toolbar. It contrasts well with the plain idea bulb and LED icons in the same set. Below 32 px the coils merge, so switch to a simpler bulb.
This is the black outline version of the spiral cfl light bulb icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
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.
