ABSTRACT:
A fluorescent lighting fixture or luminaire in which the conventional number of light source is de-lamped to a lesser number and which provides acceptable light levels and distribution of light. A flexible reflector of specular reflective material is installed in the fixture above the replacement lamp. The reflector material by virtue of its flexiblity will assume a generally parabolic configuration to re-direct the light from the fixture. Thus, with the reflector, two-lamp luminaires will de-lamp to one-lamp and four-lamp luminaires may be de-lamped to two-lamps, and so on. The invention also provides an electrical connector for positioning a new lamp at a central location and which connector is engageable in the existing lamp holders.
