Compact Fluorescent Light Bulbs Wattage Comparison

A standard a line incandescent bulb uses 50 watts.

Compact fluorescent light bulbs wattage comparison.

Typically use about 25 80 less energy than traditional incandescents saving you money. Compared to a theoretical 100 efficient lamp 680 lm w cfl lamps have lighting efficiency ranges of 7 10 versus 1 5 2 5 for incandescents. For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15. An incandescent light bulb s longevity is 2 000 hours on average.

For example a 40 watt incandescent bulb is on the dim side and uses less power while a 100 watt bulb is bright and uses a lot of juice. Cfl bulbs have much lower wattage numbers than their incandescent cousins but don t let that fool you. In general a simple rule to follow to replace an incandescent with an equivalent in light output cfl bulb is to select the cfl bulb that has 1 4 watts compared with the replaced incandescent bulb. A fluorescent light bulb s longevity is significantly higher from 6000 to 15000 hours.

The luminous efficacy of a typical cfl is 50 70 lumens per watt lm w and that of a typical incandescent lamp is 10 17 lm w. Can last 3 25 times longer. Lumen wattage comparison. 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.

An led a line bulb uses 9 watts a 41 watt savings for each bulb. The chart below illustrates the amount of brightness in lumens you can expect from different wattages of light bulbs. We are accustomed to choosing bulbs by how much electricity they use. This compact fluorescent light is ideal for ceiling fans chandeliers table lamps or wall sconces.

Using the chart we can see that if you want to replace a 40w incandescent light bulb with a compact fluorescent cfl you will likely need a 7w cfl. That s the measure of power the light bulb consumes. It produces a similar light output of 900 lumens uses 13 watt of electricity and up to 78 less energy than a standard incandescent light bulb. Designed to replace fluorescent tube bulbs these led tubes are available in 8 and 16 watts which replace traditional 25 watt and 40 watt t8 t10 t12 fluorescent tubes.

Because fluorescent lights are often installed in high ceilings in commercial sites there are additional savings because the frequency of changing bulbs is greatly reduced. Compared to traditional incandescents energy efficient lightbulbs such as halogen incandescents compact fluorescent lamps cfls and light emitting diodes leds have the following advantages.
