So to replace a traditional 60-watt bulb, buy a 15-watt CFL: 60-watt incandescent / 4 = 15 watts. Note: Some brands of 60-watt equivalent CFLs still do not seem to give off as much light as a 60watt incandescent bulb.
If the question is what wattage compact fluorescent (CFL) lamp has a similar light output to an incandescent lamp of a given wattage, the ratio is usually about 4. A 60W incandescent can be replaced by an 13-15 W CFL lamp. A 60W CFL lamp can replace a 300W incandescent lamp.
Depends on the light. Typically about 1/8th of the wattage used by an equivalent standard bulb.
Also CFL and LED light bulbs use much less actual wattage than their equivalent wattage. It is best to look at the datasheet for each individual type of light bulb. They can vary from milliwatts to kilowatts, depending on the purpose the light bulb was intended for.
Yes, Of Course The lifetime depends on the wattage. The wattage is the amount of Power the light bulb uses, and the life time depends on the power. Thank you
how much units cosumed by 15 watts cfl ina day
Usually a CFL has two ratings. The first is wattage and the second is in mA I suspect the wattage is only the wattage of the bulb itself and the second is the actual current draw of both the light bulb and the ballast. They are not compatible. If you figure the mA and multiply times the voltage you will obtain close to the actual wattage of the combination of the bulb and the ballast. I have a 100 watt Feit BPESL25T which indicates it draws 25 Watts when it actually draws 47.5 Watts. Very close to the mA (400 x 120 VAC =48 Watts) indicated on the base. Almost all CFLs I've tested with my very accurate Fluke RMS meter draw twice the wattage they indicate. Not such a good deal.
it can save 10% of per month by using cfl bulbs.
As long as the CFL has an intermediate base it can be interchangeable with any ordinary light bulb that has an intermediate base. Look on the packaging as to comparability. Look on the box for equivilant outputs between lamps to compare wattage bulbs to CFL's.
To much for your mom.
Yes, it can. CFL's are good- they don't burn as much and they're good for the environment.
Wattage of a Sanyo Bar Fridge ,please?
Yes, there are now government regulations on engery efficent lights, so this means they are all created the same way.
