Lighting apparatus

摘要

Lighting apparatus for use with fluorescent tubes. The apparatus disclosed is suited particularly for use with T5 type fluorescent tubes. Certain aspects of the invention relate to lighting units employing an extruded box-section housing providing the basis for a variety of types of light fittings and modular track-type lighting systems. Other aspects relate to light fittings and kits-of-parts enabling existing lighting installations employing, for example, T8 type fluorescent tubes to be converted for use with improved types of fluorescent tubes, such as T5 type.
