The new data on packaging may be more uniform
and informative but customers may find the change-
over initially confusing. To make things easier for
them OSRAM has developed a clear table structure
similar to the one used by the food industry to indi-
cate nutrition values and with which consumers are
now familiar.
Essential information clearly presented.

1 Watt
[
W
]
– is the unit of power and indicates energy
consumption. For incandescent lamps it was possible to
deduce the brightness of the lamp from its wattage.
2 Lumen
[
lm
]
– is the unit of luminous flux and therefore
a more informative value for the amount of light emitted by
a light source. Lumens divided by watts [lm/W] is the ratio
between the luminous flux and the amount of electrical
power consumed and indicates the efficiency of a lamp.
3 Kelvin
[
K
]
–
indicates the color temperature and therefore
the light color. The higher the value the “colder” the light.
4 R
a
– is the color rendering index. The higher the R
a
value,
the less the natural color of the illuminated object is falsified
by the artificial light. The maximum R
a
value is 100 (incan-
descent lamp).
5 Quick light – indicates how long the starting phase of a
lamp lasts – the time that elapses between the lamp being
switched on and reaching 60% of its maximum light output.
6 Dimmability
7 Average lamp life
– indicates the time that elapses until
50% of the lamps in a test group fail.
8 Average number of switching cycles
9 Mercury content of the lamp
10 Frequency
11 Lampholder
