Install LED modules to existing light fixtures

Some Definitions


A light fixture; the complete lighting unit, including lamp, reflector, ballast, socket, wiring, diffuser and housing. 

A unit of luminous flux; overall light output; quantity of light, expressed in lumens. For example, a dinner candle provides about 12 lumens and a 60-watt soft white incandescent lamps provides about 840 lumens. 

The lamp base mechanically holds the lamp in place in the application. The lamp base directly or indirectly (via a cable or lead-in wires) conducts electricity from the circuit to the lamp and can be designed to dissipate heat. Lamp bases should be operated within specified temperature range. 

Beam angle 
Also called the beam spread; the angular dimension of the cone of light from reflectorized lamps encompassing the central part of the beam out ot the angle where the intensity is 50 percent of maximum. 

A luminaire using halogen/incandescent or a high intensity 

Compact Fluorescent Lamps (CFL)

Compact fluorescent lamps employ small diameter tubes that are bent so they begin and end in a ceramic base. This allows them to be produced in a wide variety of configurations, greatly extending the applications for fluorescent lighting and offering innovative energy efficient lighting solutions. discharge (HID) lamp that produces a narrow beam angle designed to illuminate a specifically defined area. 

Ballast losses 
Power consumed by a ballast that dissipates as heat instead of being converted into light. Electronic ballasts operate more efficiently than magnetic or hybrid ballasts. A typical ballast loss for a standard two lamp magnetic ballast is 20 watts, which an electronic equivalent would only be 7 watts. 

The rate at which energy is taken from an electrical system or dissipated by a load, expressed in watts; power that is generated by a utility is typically expressed in volt-amperes. 

A unit of electrical power. Lamps are rated in watts to indicate power consumption. Also see Nominal watts. 

Power factor 
A measure of the effectiveness with which an electrical device converts volt-amperes to watts; devices with power factors (0.90) are "high power factor" devices.
