Jul 13, 2022 · Use this chart to determine how many lumens you’ll need from your next light bulb. For example, if you typically purchase 60W incandescent bulbs, which produce about 700-800 lumens, consider purchasing a lower energy alternative like a 42W halogen bulb, 12W CFL, or even a 10W LED bulb to achieve the same brightness.

Mar 9, 2018 · CFL (compact fluorescent lamp) light bulbs were the first real energy-efficient alternative to incandescent and halogen bulbs, using much less energy and lasting for much longer. LED light bulbs take energy efficiency to another level, using around 40% less energy than CFL equivalents.

Watts measure the amount of energy a bulb consumes. For example, a 100W bulb needs 100 watts to operate. Consequently, the more watts used, the higher your energy bill is. With the use of incandescent 60W bulbs for many years, we’ve associated watts with brightness. After developing LED technology, we can’t do that anymore. That’s because LED bulbs...
Now with LED bulbs around, we need to focus more on the lumens rather than wattage. Lumens measure the level of brightness produced by a light bulb. Obviously, the higher the lumens, the brighter a bulb illuminates. Recently, manufacturers started to declare the lumens of each bulb on its package to clear the confusion.
The relation between a bulb’s wattage and the lumens it produces can help us measure its luminous efficiency. This term refers to the lumens created per each watt consumed. In other words, luminous efficiency indicates how economical the bulb is in converting watts into lumens. For example, a 60W incandescent bulb produces 800 lumens. This means th...
Equivalent wattage is a term used to describe the brightness of an LED bulb in comparison with incandescent lamps. For example, when you see the phrase “60W equivalent” on an LED light bulb, it doesn’t mean it consumes 60W. Instead, it means the bulb produces as many lumens as a 60W incandescent, which is 800 lumens. Having said that, a 60W equival...
Replacing incandescent with LED bulbs isn’t the default. In other situations, you may need to replace a halogen bulb or even a CFL one. After all, an LED light source is the most energy-efficient of all. So, are all types of bulbs the same when it comes to LED equivalent wattage? The answer is: No, they’re not. Different types of bulbs consume diff...

Depending on the bulb and the manufacturer, LED technology typically produces 75-110 lumens/watt. So, LEDs are generally about 7 times more efficient at producing light than incandescent bulbs. Use a 7:1 ratio as a rough guide when selecting an LED bulb to replace an incandescent bulb.

Nov 18, 2022 · LEDs are far more efficient at converting electricity, measured in watts, into light, measured in lumens. As such, a typical 4 watt LED bulb can easily achieve a light output comparable to a 50 watt halogen, sometimes higher due to its high lumen to watt ratio.
