Many of thse bulbs are also available in a variety of different cap types to fit a wide range of different fittings.
There are two main types of dimmable energy saving bulbs;
- smooth dimming, these work exactly like a normal dimmable bulb and are compatable with most dimmer switches (please ask if in doubt..)
- switch dimming, this variety work on normal on/off switches and can dim by flicking the switch on and off. This is difficult to explain in writing but actually provides a very sensible solution and works very well in practice. No need for re-wiring or debate about the correct brightness to suit a location these simply work in a wide range of applications and can be dimmed for soft mood lighting - perfect.
