Buying Bulbs Based on Lumens
In addition to the new labels telling us how bright light bulbs are, there is some other important information, such as:
- Estimated yearly energy cost
- Lifespan of the bulb
- Light appearance (warm to cool)
- Energy used
So, the next challenge is to learn what lumens to use around the house. Here is a rule of thumb:
- To replace a 100-watt incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for fewer 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.
