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.
No, it is not recommended to use a 100 watt CFL in a fixture that specifies a maximum of 25 incandescent watts. CFL bulbs have different wattage equivalencies compared to incandescent bulbs, so you should use a CFL bulb that is equivalent to or lower than the specified incandescent wattage for the fixture. Using a higher wattage CFL bulb can cause overheating and potentially pose a fire hazard.
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.
how much units cosumed by 15 watts cfl ina day
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
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.
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.
The wattage needed for a light bulb depends on the brightness desired. For example, a typical 60-watt incandescent bulb produces around 800 lumens. Energy-efficient LED bulbs can produce the same amount of light using much less wattage, typically around 8-10 watts.
Wattage of a Sanyo Bar Fridge ,please?
it uses about 50v
