Lightbulbs targeted by guerrilla greens

The Light Brigade have been swooping on stores and fixing bright orange stickers to non-energy-efficient bulbs, describing them as "old", "wasteful" and "past their sell-by date".

They have also been delivering giant manifestos to store headquarters across the country asking retailers to remove the old bulbs from their shelves by the end of 2007.

They have threatened retailers with a "visitation" if they fail to comply.
