40w Standard light bulbs

These GLS bulbs are the standard type that have been used in homes for decades. They offer the familiar warm white glow of traditional incandescent light bulbs, and are available with the standard B22d bayonet cap (BC) or E27 Edison Screw (ES) cap.

If you're unsure of what bulb to install in your ceiling light, this is the safest option, as it is the one most commonly used today, and its wattage is low enough to suit most standard light fixtures. If you need help finding the right cap type, this guide will help.
