20W ES Switch Dimmable Spiral Energy Saving Bulb

16.000 HOURS LIFE TIME!!!

(During the lifetime of this light bulb you can expect to save over £100 on energy bills and reduce CO2 emissions by over half a tonne!)

Thanks to the brand new innovative ballast technology, flicking the switch on and off puts the lamp into a dimming cycle. Once the desired brightness is reached another flick of the switch sets the light level. This level is stored and the lamp will illuminate at this level (even if it is at the minimum) until the level is reset.

How to use:

1. Each time the lamp is switched on it comes on at the same brightness it was last switched off at.
2. To change the brightness, switch off and then on again within 1 second; the lamp starts to cycle smoothly down and then up again.
3. When the brightness you want is reached, switch off and on again. The lamp is now set at this brightness until you want to change it. To change the brightness, follow these steps again.

Important: Do NOT attempt to use this bulb with a dimmer switch. This may damage the light bulb beyond repair. This light bulb contains its own dimmer. Use with a conventional light switch!
