Frosted Bulb

A bulb with a diffused white coating that softens light output, hides internal LED chips, and reduces glare.

Frosted bulbs have a white coating on the inside of the glass that scatters light in every direction, producing a soft, even glow. This diffusion hides the bright LED chips inside, eliminating the harsh point-source glare that can be uncomfortable when a bare bulb is visible.

Choose frosted when the bulb is exposed or visible in the fixture — like a table lamp with a translucent shade, an open pendant, or a bathroom vanity bar. The frosted coating doesn't significantly reduce total light output, but it does change the quality: shadows are softer, the light feels more gentle, and there are no visible hotspots.

The trade-off is aesthetic. Frosted bulbs don't have the sparkle and visual interest of clear filament bulbs. In a chandelier or decorative fixture where the bulb itself is part of the design, a frosted bulb can look flat and utilitarian.
