To examine the cost comparison let s take a look at a standard 60 watt replacement incandescent bulb in this example.
10 watt led equivalent incandescent.
Since most household bulbs are 40w 60w 75w or 100w you may be able to memorize their equivalent lumens.
For an led running over the course of 10 years the actual cost would be only 18 to operate.
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.
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.
Say you normally use a 60 watt incandescent bulb for example.
A 40 watt equivalent led bulb consumes only 6 to 8 5 watts.
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.
Dimmable from 100 to 10 these bulbs have a 200 degree beam angle to cast light in a wide area.
The energy consumption to use a bulb like this would cost about 90 over the course of 10 years.
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.
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.
Leds require less wattage than cfl for the same amount of light.
For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15.
Click the equivalent wattage in the lumens vs.
While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs.
