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).

Check the packaging to get the right brightness

Make sure you get the right brightness of efficient light bulb by checking the box – the wattage and type of inefficient bulb they replace is usually clearly displayed. Otherwise, look for lumens (the amount of light it puts out) to ensure you get the right amount of light for your needs. As a rough guide, 1350 lumens is the equivalent of a traditional 100W light bulb, a 20W CFL and a 75W halogen.
