Amalgam Lamps
OSRAM DULUX® T CONSTANT and OSRAM DULUX® T/E CONSTANT
with triple-turn tubes have been optimized for constant lumen output under variation of lamp am-
bient temperature, such as operation in narrow downlights in which high ambient temperatures may
occur or outdoor applications. Thanks to their special amalgam technology used, the luminous flux
remains more or less constant over a wide range of temperatures (see 4.6.2). CONSTANT lamps are
identical in construction to the OSRAM DULUX
® T and T/E lamps except for their rounded tube
cross-section at the glass tube bend and a shorter discharge tube (about 5 mm shorter).

OSRAM DULUX ® T/E CONSTANT is the four-pin version with a GX24q base. It uses the same elec-
tronic control gear as OSRAM DULUX ® D/E and T/E. These lamps can be dimmed with certain re-
strictions (see 4.7.1 Dimming of OSRAM DULUX CONSTANT lamps, p. 67).
These lamps are not suitable for emergency lighting to DIN EN 1838.
OSRAM DULUX ® T/E CONSTANT lamps, particularly the high-wattage models, can be used in out-
door light fittings of suitable dimensions.
