Compact Fluorescent Light Bulbs Wattage Comparison

Can last 3 25 times longer.

Compact fluorescent light bulbs wattage comparison.

That s the measure of power the light bulb consumes. 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. A fluorescent light bulb s longevity is significantly higher from 6000 to 15000 hours. Cfl bulbs have much lower wattage numbers than their incandescent cousins but don t let that fool you.

Typically use about 25 80 less energy than traditional incandescents saving you money. This compact fluorescent light is ideal for ceiling fans chandeliers table lamps or wall sconces. Similarly if you want to replace your 53w halogen light bulb with a modern led the led will probably use between 9 and 13 watts of energy. An incandescent light bulb s longevity is 2 000 hours on average.

Lumen wattage comparison. 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. For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15. We are accustomed to choosing bulbs by how much electricity they use.

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. 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. 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. 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.

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. Due to a physical process that is utilized in incandescent bulbs they are sensitive to voltage changes. 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.

To help give you a little perspective let s compare the wattage between an incandescent light bulb and an led light bulb. A standard a line incandescent bulb uses 50 watts.
