Background information on Compact Fluorescents

Compact fluorescent lamps with 2-pin or 4-pin fittings are used with luminaires containing control gear to match the characteristics of the lamp. Different fittings are designed to ensure that only lamps of the correct rating can be installed thus matching the lamp to the control gear. Most lamps are available in a variety of colours ranging from extra-warm white (827) to cool white (840) and sometimes daylight (860 or 865).

Please refer to our colour reference table for more information.
