Energy-saver light bulbs save you money and also help conserve the country’s energy resources. But which ones give the best light output and keep on switching on? We tested 19 different models – and found a wide variation in performance.

We also look at the options for using energy-efficient lighting to create various moods around your home, and our light bulb calculator will show you how much money you could save by changing to energy efficient light bulbs.
