The high quality brand name compact fluorescent lamp with integrated option for

varying the light.

• The lighting level can be varied by simply switching the lamp off and on again.

Within 3 seconds the luminous flux is reduced to about 25 % of the rated value.

Switching the lamp off and on again takes the lamp back up to 100 % luminous flux,

irrespective of how long it is switched off. Recommendation: allow the lamps to burn

in at full load for at least 1 minute each time before „dimming to around 25 %“ to

achieve stable operation

• Additional energy savings from reducing power consumption to 40 %. For more

information see Section 3.5.3 Dimmer operation

• In accordance with IEC regulations, OSRAM DULUX® EL LONGLIFE VARIO can

be switched on and off any number of times within its average life of 15000 hours

and within its permitted temperature range of +15°C to +50°C without having to be

switched off for a certain amount of time before being switched on again

• Not suitable for use with existing dimmer systems, DC power, emergency lighting

systems or electronic switches
