What is the point in having a “nutritional value table”
for lamps?
As there are so many different modern alternatives to con-
ventional incandescent lamps, your customers have to take
many more criteria into consideration when purchasing a
lamp: These include the light color, color reproduction index
and the dimming capacity. To make this easier for you,
OSRAM has developed a clearly structured table based on
the familiar nutritional value table already established in
the food industry. Here is the most important information
at a glance.
1
Watt [W] is the unit of power and a value indicating energy
consumption. When the incandescent lamp was the only
lamp available, the consumer simply referred to the power
rating to determine the brightness of the lamp.
2
Lumen [lm] is the unit of light fl ux and an important value
indicating the quantity of light emitted by a light source
inside a room. Dividing the lumen value by the watt rating
[lm/W] produces the ratio between the light fl ux and the
consumed power, which indicates the effi ciency 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 artifi cial light distorts the color of an illuminated
object. The maximum R
a
value is 100 (incandescent lamp).
5
Delay time indicates how long the lamp start phase lasts –
that period of time which the lamp takes to reach 60 % of
the maximum light quantity after being switched on.
6
Dimming capacity
7
Average lamp service life indicates the time it takes for
50 % of the lamps in a test group to fail.
