OSRAM DULUX® EL lamps are compact fluorescent lamps with integrated electronic

control gear for mains voltage from 220 to 240 V. The lamps are available with E14 or

E27 screw bases or B22d bayonet bases, which means they are quick and simple

direct replacements for ordinary light bulbs. They offer the dual benefits of the comfort

of a ordinary light bulb and the economy of a fluorescent lamp.

OSRAM DULUX® EL lamps are particular economical. They have a reputation as „long-

distance runners“ because they consume very little electricity.

At 0.13

€/kWh, none cost more than 1/3 € Cent per hour to run.

OSRAM DULUX® EL is available in LONGLIFE and ECONOMY versions with the

following characteristics:

Main areas of application for OSRAM DULUX® compact fluorescent lamps

are as follows:

1. In the commercial sector: e. g. restaurants, hotels, ticket offices, foyers,

corridors, offices

In view of the enormous savings in electricity and replacement costs, these lamps

are ideal for areas where continous lighting is needed.

2. In the domestic sector: e. g. in living rooms and the kitchen.

OSRAM DULUX® EL LONGLIFE are needed if there are high demands to be met in

terms of lamp life and frequent on/off switching.

OSRAM DULUX® EL compact fluorescent lamps carry the CE symbol of the EU and

comply with all the relevant European standards, in particular the following:

– EN 60968

(safety requirements)

– EN 60969

(performance requirements)

– EN 61000-3-2 (mains current harmonics)

– EN 55015

(RFI suppression)

– EN 61547

(EMC Immunity Requirements)
