The mantra of switching to energy-efficient lightbulbs is the eco-tip equivalent of Genesis to Christians; it's the oldest one in the book. So we're going to assume you've switched most of your standard light fittings to energy-saving compact fluorescent bulbs (CFLs) already, saving yourself around £60 over each bulb's lifetime.
You might not, however, have got round to greening your task lighting and mood lighting -- the lights you use for reading and chilling out with. So below we've rounded up five great lights that take energy efficiency a step further. All these models use light emitting diodes -- better known as LEDs -- which are even more efficient than CFLs.
Because LEDs are still cutting-edge technology for real-world products, none of these lamps has a cheap up-front price -- but they will last an incredibly long time. Luminair's Eco Desk 36, for example, will run for 100,000 hours. That's 11 years with the light on 24/7. Forget about bags for life: these are lamps for life.
