The high quality brand name compact fluorescent lamp for standard E27 and B22d

light bulb holders.

• About 12 years life (if used for around 3 hours a day)

• Wide range from 5 W to 23 W and up to four different colour appearances

• OSRAM DULUX® EL LONGLIFE E27 lamps are suitable for most light bulb fittings

because of their compact dimensions

• Ideal for all applications that require long life and an ability to withstand frequent

on/off switching

• On/off switching as for ordinary light bulbs with no reduction in life (500.000 switching

operations possible in a 30 s on/150 s off cycle)

• OSRAM DULUX® EL LONGLIFE 5 W and 7 W are suitable for continuous operation

on DC power supplies with restrictions (see also 3.5.2.1)

• Some OSRAM DULUX® EL lamps are also available for other mains voltages

(e. g. 120 V) and other bases (with different technical data)

• Not suitable for use with dimmers, electronic switches or motion detectors
