This Information Paper outlines the advantages of LED lighting and explains the parameters that need to be specified for LED installations. These include the amount and direction of the output light, glare, lifetime and colour quality. LEDs perform less well at high temperatures, so their fittings require heat sinks or ventilation to keep them cool. Organic LEDs, which are polymer sheets emitting a diffuse light, are also briefly reviewed. This Information Paper is intended for building owners and facilities managers, interior designers, electrical installers and services engineers. 8 pages.
