This is a widely used lamp base for 6-V up to 24-V light bulbs installed on cardboard, light wood, plastics and metal surfaces.
The screw base in E10B21 lamp bases are elevated to prevent short circuit when installed on metal surfaces and keeps away the heat when mounted on cardboard or light wood surfaces. If you intend to install the lamp holder under the hood of a car or inside a metal cabinet, then E10B21 lamp bases may be your best choice.
The legs have rivet/screw holes used for easy mounting while they are also the negative contacts of the lamp base. Another smaller contact between the two legs is used to connect the positive wire.
This lamp holder matches all of our miniature lamps.
E10B21 lamp base is for low voltage applications. It is not recommended for applications that require more than 24 Volts.
Also known as lamp base, lamp stand and lampholder.
