What is the signifi cance of the energy effi ciency label
on the lamp packaging?
The system for categorizing products into seven effi ciency
classes from G (very ineffi cient) to A (extremely effi cient)
helps your customer to assess the economic effi ciency of
a product at a glance and already appears on a host of
other electrical devices. Classifi cation examples:
• Compact fl uorescent and LED lamps – Classes A and B
• Halogen lamps – Predominantly classes C and D
• Conventional incandescent lamps – Mostly classes E
and F
Responsible use of mercury.
Most OSRAM compact fl uorescent lamps con-
tain up to 2.5 milligrams of mercury with a vol-
ume of less than 0.2 mm
3
; a quantity that is
small enough to cover the tip of a ballpoint
pen.
The amount of mercury used in a single clinical
thermometer exceeds 1000 milligrams, which
would be enough for 300 – 1000 compact fl uo-
rescent lamps.
OSRAM uses advanced measuring technology
to reduce the amount of mercury used in the
manufacture of lamps to a minimum.
Compact fl uorescent lamps must be disposed
of at a recycling depot. OSRAM has played an
important role in developing a functional sys-
tem for collecting and recycling lamps. In the
meantime, an increasing number of trade part-
ners are providing disposal boxes for used
lamps.
Compact fl uorescent lamps help prevent the
emission
of mercury – even though they them-
selves contain mercury. Coal power stations
emit far more mercury than is used in compact
fl uorescent lamps. If less electricity has to
be generated because of the use of compact
fl uorescent lamps, mercury emissions are
reduced.
Calculating the energy
effi ciency class
The class is calculated according
to Annex IV of Directive 98/11/EC
from the EU Commission using
measured light fl ux and lamp
power values.
