OSRAM DULUX® EL – electronic energy saving lamps

Economical alternatives to ordinary light bulbs

Technical Guide

OSRAM DULUX® EL

and the environment

4.1 Energy balance

4.2 Substances

Whenever energy is used there is an impact on the environment. This impact

principally takes the form of the release of carbon dioxide (CO2) when electricity is

generated in fossil fueled power stations (1 kWh of electricity = 1 kg of CO2 emissions*).

The CO2 contributes significantly to the „greenhouse effect“, or global warming.

Saving energy is therefore of utmost importance for environmental protection and

for OSRAM.

Compared with ordinary light bulbs, all OSRAM DULUX® EL LONGLIFE and

ECONOMY lamps not only save energy during their lives, they need less energy for

their manufacture.

* For an assumed efficiency of 37 % (power station + power distribution), a molecular

weight for CO2 of 44 and a thermal value of 10 kWh per 1 kg of coal (carbon), 1kg

CO2 is produced per 1 kWh of generated energy.

Like all discharge lamps, OSRAM DULUX® EL LONGLIFE and ECONOMY lamps are

enclosed systems in normal use. Apart from emitting light, they therefore can have no

impact on the environment.

A major substance in discharge lamps that is potentially harmful to the environment is

mercury. Without it, however, the lamps would not work. Thanks to a patented dosing

procedure, OSRAM has succeeded in reducing the mercury content to less than 3 mg

per lamp.

OSRAM DULUX® EL LONGLIFE and ECONOMY lamps contain no radioactive

substances.

What’s more, mercury is released when energy is generated from fossil fuels, which

means that in this respect the environmental impact of incandescent lamps is much

greater than that of compact fluorescent lamps even allowing for the mercury in the

compact fluorescent lamp.

All OSRAM DULUX® EL LONGLIFE and ECONOMY lamps are environmentally friendly

products because of their energy savings and the associated reduced environment

impact (carbon dioxide and mercury).
