Introduction
The first compact fluorescent lamps (CFLs) appeared on the European market at the
start of the 1980s. Today, compact fluorescent lamps are available in an extremely
wide range of models. They have had a significant and lasting effect on luminaire
design and lighting applications.
Compact fluorescent lamps can be divided into two main groups:
Lamps with E27 and E14 screw bases and integrated control gear (electronic or conven-
tional) are available in wattages from 3 to 24 W and constitute a separate family of lamps.
Lamps of this type are the OSRAM DULUX
ges are intended as direct replacements for ordinary light bulbs. For detailed technical
information on these lamps, please refer to the brochure entitled „OSRAM DULUX
Electronic Energy-Saving Lamps – Facts and Technical Data“.
This present guide, however, takes a detailed look at lamps with pin bases.
OSRAM’s compact fluorescent lamps with pin bases marketed under the
OSRAM DULUX
flux values of 250 to 6000 lm. This range of values covers a broad spectrum of lamps,
including incandescents, fluorescents and HID lamps, with a wide variety of appli-
cations.
Lamps with pin bases have a history of constant development, from the single-turn
OSRAM DULUX
tive triple-turn tubes. The development of different shapes and wattages has led to
many different types of luminaire for indoor and outdoor lighting. The list includes
recessed and surface-mounted luminaires for shops and offices, floor-standing lights,
indirect luminaires, workplace and desktop lighting, security lighting, pictogram illumi-
nation, street lighting, solar luminaires and downlights. For downlights in particular,
pin-based lamps have been instrumental in determining their design, as each succes-
sive round of development has produced increasingly shorter lamps of greater light
output.
Compact fluorescent lamps from OSRAM, which offer impressive economy thanks to a
luminous efficacy of up to 85 lm/W and a lamp life of up to 8000 or 10000 hours depen-
ding on the operating mode, are available not only in a wide range of types but also in
different light colours. These light colours are classified in colour rendering groups 1B
(Ra 80 to 89) and 1A (Ra 90 to 100). The range also includes various models for special
applications in medicine, cosmetics and technology.
