In the past, we bought light bulbs based on how much energy, or watts, they use. Wouldn't it make more sense to buy lights based on how much light they provide?
When you're shopping for light bulbs, you can choose your next light bulb for the brightness you want by comparing lumens instead of watts. A lumen is a measure of the amount of brightness of a light bulb, the higher the number of lumens, the brighter the light bulb.
WHAT'S A LUMEN?
Lumens measure how much light you are getting from a bulb. More lumens means it's a brighter light; fewer lumens means it's a dimmer light.
Lumens are to light what kgs are to bananas, litres are to milk. Lumens let you buy the amount of light you want. So when buying your new bulbs, think lumens, not watts.
LUMENS AND LED LIGHTING
The brightness, or lumen levels, of the lights in your home may vary widely, so here are rules of thumb to understand the relationship between lumens and led lighting power ratings:
To replace a 100 watt (W) incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for less lumens; if you prefer brighter light, look for more lumens
- Replace a 75W bulb with an energy-saving bulb that gives you about 1100 lumens
- Replace a 60W bulb with an energy-saving bulb that gives you about 800 lumens
- Replace a 40W bulb with an energy-saving bulb that gives you about 450 lumens.
