Thanks to new amalgam technology, we
can now offer a new family of lamps – the
CONSTANT series. These innovative compact

This thermographic comparison reveals that an incandescent
lamp converts 95% of its electrical energy into
heat and only 5% into light. OSRAM DULUX ® EL produces
the same amount of light from 80% less electricity.
DULUX ® L CONSTANT – offer high luminous
flux over a wide range of temperatures.
90% is achieved between +5 °C and +70 °C.
They can therefore be used in outdoor
applications and also in high-intensity
downlights.
Long life:
the ENDURA ® system.
The ENDURA ® system has been developed
specifically for places where relamping
involves extremely high costs, such
as in tunnels or factories. The OSRAM
ENDURA ® lamp has system life of 60,000
hours. And it provides quantities of light
that other fluorescent lamps simply cannot
match. The 70 W version produces 6500
lumen, the 100 W version 8000 lumen
and the 150 W version 12,000 lumen.
At 80 lm/W, its luminous efficacy is also
higher than that of any other electrodeless
fluorescent lamp. Its low height
means that it can be used in low-profile
luminaires.
