1.2.5 Lamps for special Applications:
In some cases the design of the light fitting, or the application itself, put special demands on the
lamps. The lamps may, for example, have to operate at high ambient temperatures or they may
have to ignite and operate at low ambient temperatures. There have been special lamps developed,
as well as some of the ranges of existing lamps have been modified to meet these special require-
ments:
OSRAM DULUX ® L SP (four-pin base).
Amalgam lamps:
OSRAM DULUX ® T CONSTANT (two-pin base)
OSRAM DULUX ® T/E CONSTANT (four-pin base)
OSRAM DULUX ® L CONSTANT (four-pin base)

OSRAM DULUX ® L SP for outdoor lighting has been developed specifically for large volume venti-
lated light fittings and for cool climates. These lamps produce their maximum luminous flux at a
lower temperature than conventional compact lamps (see 4.6.3 Luminous flux/temperature graphs
for OSRAM DULUX
® CONSTANT lamps, p. 64). Apart from their rounded tube ends, they are iden-
tical in construction to OSRAM DULUX ® L lamps and are operated with the same conventional or
electronic control gear.
