Everything you've ever wanted to know about light bulbs...

A bulb a day keeps climate change at bay (or something along those lines...)

We've had a lot of support for our current light bulbs campaign (and some detractors too, it has to be said) but there have been many queries about whether compact fluorescent lamps (CFLs) really are what they're cracked up to be - what about the mercury, can they be recycled, that sort of thing. Many of them have already been covered elsewhere on the site, but it's worth following them up in a slightly more prominent position.

If you have any more queries, just post a comment below or contact us at info@uk.greenpeace.org.
