Lightbulbs are boring

Actually that's true. Next.

You can't use them with dimmer switches

Not so! The fabulously named Megaman (one of our first 10:10 businesses) and other brands produce low-energy dimmable bulbs. They cost a bit more than regular types, but will still save you epic amounts of cash and carbon.

They flicker and take ages to get going

In the bad old days, turning on a low energy bulb was a bit like watching a cross between a disco and a sun rise. The latest models, however, fire up right away and get up to full power within seconds. Progress is a wonderful thing.

They can't replace halogen spots and other unusual fittings

Nowadays, the eco bulb club is a tolerant and permissive place, with models for even the weirdest light fittings. Halogen spots (the ones everyone has hundreds of in their kitchen) are no problem. Behold!

They're too pricey

The old energy guzzlers are a bit cheaper up front, but once you get them home they’ll rob you blind with all the power they need. Energy savers have a bit more class. They start at about a pound each, and will save you about £50 overall. That's dinner, a film, and a bit less climate change. Not bad.

They’re ugly

Even by lightbulb standards, regular low energy bulbs aren’t exactly overflowing with rustic charm. But these days they’re increasingly being made in the friendlier shapes we’re used to.

Don’t they have mercury in them?

There’s actually less mercury inside each low-energy bulb than would come from a coal-fired power station producing the extra electricity an old bulb needs. So there. But you still probably shouldn’t merrily smash them into your bedroom waste paper basket. Check your local council’s website for advice on where to drop them off.
