Comparison Of Incandescent Fluorescent And Led Light Bulbs

While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs.

Comparison of incandescent fluorescent and led light bulbs. Lumens are listed under brightness. Examine the label of the led bulbs at the store. Most leds come with a minimum 2 year guarantee. For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15.

After all they are much more energy efficient. 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. In the table below you can see how lumens roughly translate into watts according to different types of light bulbs. Due to a physical process that is utilized in incandescent bulbs they are sensitive to voltage changes.

Bulb packaging now has a lighting facts label to inform you about the bulb s lumens wattage used lifespan and cost to operate. An incandescent light bulb s longevity is 2 000 hours on average. That is five presidential elections time for a home remodeling and the expanse of an entire generation. 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.

The chart below illustrates the amount of brightness in lumens you can expect from different wattages of light bulbs. 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. Leds require less wattage than cfl for the same amount of light. Equivalent wattages and light output of incandescent cfl and led bulbs.

Find a bulb that matches the lumens you need to replace your incandescent bulbs. These light bulbs also require a lot more watts and electricity. Any defective led bulb will usually fail within this time. 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. What is 50 000 hours. A fluorescent light bulb s longevity is significantly higher from 6000 to 15000 hours. The bulbs we ve taken into consideration here are the old incandescent ones led s as well as fluorescent bulbs cfl.

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. It is 50 times the life of a typical incandescent bulb and 5 times the lifetime of an average compact fluorescent lamp cfl. Incandescent bulbs typically only last a mere 750 hours compared to the longer lasting led and cfl bulbs. A cfl uses less than 15 watts and costs only about 75 of electricity per year.
