So whatever you want to light up – there’s an energy saving bulb that’s right for the job.

Below are some tips on how to choose an efficient light bulb replacement.

Know what type of bulb you’re replacing

Look at how bright it is (the wattage, written on the bulb), whether it puts out a warm or cool colour, what type of bulb it is (bayonet, screw-in or pins), and whether it’s an unusual shape or size (if so, it may pay to take it with you to the shop).
