Comparison of incandescent fluorescent and led light bulbs.
In the table below you can see how lumens roughly translate into watts according to different types of light bulbs.
It is 50 times the life of a typical incandescent bulb and 5 times the lifetime of an average compact fluorescent lamp cfl.
Led bulbs require much less wattage than cfl or incandescent light bulbs which is why leds are more energy efficient and longer lasting than their competitors.
A fluorescent light bulb s longevity is significantly higher from 6000 to 15000 hours.
Find a bulb that matches the lumens you need to replace your incandescent bulbs.
An incandescent light bulb s longevity is 2 000 hours on average.
What is 50 000 hours.
The more lumens a light bulb produces the brighter it shines.
The chart below illustrates the amount of brightness in lumens you can expect from different wattages of light bulbs.
If you were to light an incandescent bulb for 25 000 hours it would cost 169 compared to the 30 cost to light an led.
Incandescent bulbs typically only last a mere 750 hours compared to the longer lasting led and cfl bulbs.
For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15.
In fact if you ran a led for 6 hours per day every day it would last for nearly 23 years.
Most leds come with a minimum 2 year guarantee.
Examine the label of the led bulbs at the store.
While fluorescent cfl bulbs generate light by sending an electrical discharge through an ionized gas incandescent bulbs emit light by heating the filament present in the bulb.
Incandescent bulbs and cfl bulbs are more easily broken than leds which increases their cost of use.
Any defective led bulb will usually fail within this time.
Lumens are listed under brightness.
While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs.
When cfl bulbs were first introduced in the 1970s they were expected to spell the end of the traditional incandescent light bulb.
Lumen wattage comparison.
These light bulbs also require a lot more watts and electricity.
Equivalent wattages and light output of incandescent cfl and led bulbs.
After all they are much more energy efficient.
Leds require less wattage than cfl for the same amount of light.
Compared to a 60 watt incandescent light bulb which draws more than 300 worth of electricity per year and provides about 800 lumens of light both bulbs save significantly more energy.
Due to a physical process that is utilized in incandescent bulbs they are sensitive to voltage changes.
