Comparison Of Incandescent Fluorescent And Led Light Bulbs

The more lumens a light bulb produces the brighter it shines.

Comparison of incandescent fluorescent and led light bulbs.

In fact if you ran a led for 6 hours per day every day it would last for nearly 23 years. 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. These light bulbs also require a lot more watts and electricity. Any defective led bulb will usually fail within this time.

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. A cfl uses less than 15 watts and costs only about 75 of electricity per year. It is 50 times the life of a typical incandescent bulb and 5 times the lifetime of an average compact fluorescent lamp cfl.

A fluorescent light bulb s longevity is significantly higher from 6000 to 15000 hours. While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs. What is 50 000 hours. When cfl bulbs were first introduced in the 1970s they were expected to spell the end of the traditional incandescent light bulb.

The chart below illustrates the amount of brightness in lumens you can expect from different wattages of light bulbs. Examine the label of the led bulbs at the store. Incandescent bulbs typically only last a mere 750 hours compared to the longer lasting led and cfl bulbs. Bulb packaging now has a lighting facts label to inform you about the bulb s lumens wattage used lifespan and cost to operate.

Equivalent wattages and light output of incandescent cfl and led bulbs. Most leds come with a minimum 2 year guarantee. The bulbs we ve taken into consideration here are the old incandescent ones led s as well as fluorescent bulbs cfl. 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.

Due to a physical process that is utilized in incandescent bulbs they are sensitive to voltage changes. After all they are much more energy efficient. Lumens are listed under brightness. An incandescent light bulb s longevity is 2 000 hours on average.

In the table below you can see how lumens roughly translate into watts according to different types of light bulbs. Find a bulb that matches the lumens you need to replace your incandescent bulbs. Incandescent bulbs and cfl bulbs are more easily broken than leds which increases their cost of use. That is five presidential elections time for a home remodeling and the expanse of an entire generation.
