See energy saving bulbs in a new light
In your mind's eye think of an energy saving bulb, is it bulky and oddly shaped? Maybe giving off a cold, harsh light?

If so, be prepared to think again. There are now more good reasons than ever to buy energy saving lightbulbs. Here are some of the best.

Advances in technology mean that energy saving lightbulbs are now available in a wide variety of fittings, shapes and sizes.

Like standard bulbs, they come in all shapes and sizes
These range from stick shaped bulbs candle shaped varieties, with small or medium screw and bayonet fittings.

The choice really is yours. Nowadays, there are even halogen and dimmable energy saving bulbs on the market.

And thanks to the invention of 'soft tone' bulbs, you can enjoy a warm glow rather than a cold light.
