While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs.
10 watt led equivalent incandescent.
The led equivalent of a 60 watt a19 bulb consumes only between 9 and 12 watts and provides about the same light output measured in lumens.
A 40 watt equivalent led bulb consumes only 6 to 8 5 watts.
Superior light quality non flickering light and zero harsh glares prevents eye fatigue and provides a comfortable stress free atmosphere.
Say you normally use a 60 watt incandescent bulb for example.
Dimmable globe led bulbs designed for bathroom vanities or anywhere a globe bulb is required these bulbs produce light equivalent to a 40 watt incandescent bulb yet only consume 10 watts of power.
You would probably want to choose an led bulb that uses 8 to 12 watts and has a lumen rating of 800 to get the same illumination.
For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15.
Watts chart below to shop for the right light bulb for your space.
To examine the cost comparison let s take a look at a standard 60 watt replacement incandescent bulb in this example.
Some cfl and led bulbs will put their wattage equivalents on the box while many don t so this chart should help give you a good idea of how bright your new bulb is going to be.
Energy saving illuminating with the equivalent of a 60 watt incandescent bulb but only consumes 9w of power making these daylight led bulbs one of the best energy efficient lighting.
Click the equivalent wattage in the lumens vs.
Leds require less wattage than cfl for the same amount of light.
However because lumens per watt vary for both incandescent and led lights it s easier to use a wattage to lumens comparison chart.
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.
For an led running over the course of 10 years the actual cost would be only 18 to operate.
Incandescent light bulb wattage led equivalent wattage 100 watt 10 watt 75 watt 7 5 watt 60 watt 6 watt 50 watt 5 watt 30 watt 3 watt led equivalents to halogen light bulbs halogen light bulbs are more efficient than traditional incandescent bulbs but still require much more energy to generate light than leds which use around 85 less energy.
