electrode

Lights & lighting; Lighting products

Any metal terminal emitting or collecting charged particles, typically inside the chamber of a gas discharge lamp. In a fluorescent lamp, the electrodes are typically metal filaments coated with ...

electrodeless lamps

Lights & lighting; Lighting products

Light sources where the discharge occurs in a chamber with no electrodes (no metal.) The energy for the discharge is supplied by radio frequency excitation, e.g. microwaves (See GENURA).

electromagnetic ballast (magnetic ballast)

Lights & lighting; Lighting products

A ballast used with discharge lamps that consists primarily of transformer-like copper windings on a steel or iron core. Also called "Core and Coil". (See ELECTRONIC BALLASTS).

A continuum of electric and magnetic radiation that can be characterized by wavelength or frequency. Visible light encompasses a small part of the electromagnetic spectrum in the region from about ...

electronic ballast

Lights & lighting; Lighting products

A short name for a fluorescent high frequency electronic ballast. Electronic ballasts use solid state electronic components and typically operate fluorescent lamps at frequencies in the range of ...

elliptical reflector (ER) lamp

Lights & lighting; Lighting products

An incandescent lamp with a built-in elliptically-shaped reflecting surface. This shape produces a focal point directly in front of the lamp which reduces the light absorption in some types of ...

electromagnetic inference (EMI)

Lights & lighting; Lighting products

High frequency electronic ballasts and other electronic devices can produce a small amount of radio waves which can interfere with radio and TV. Federal mandated requirements must be met for EMI ...
