Wattage only tells you the amount of energy a bulb uses. To see the actual amount of light a bulb really produces – and compare classic, LED and energy-saving light bulbs – you need to know the lumen value (lm). The higher it is, the more light the bulb gives. This guide shows you what to look for when choosing a bulb and how to find this on the packaging.
