If i have a 100 watt light bulb can i use a light bulb as low as 13 in its place?

Question

i want to save money and energy! give me more tips if you like!

Answer 1

First where can any one find a 13w light bulb?

That light will be only as bright as a night light.  You'll need so many that you'll use more energy than if you just kept the 100w bulb in first place.

Use 75w or 60w bulbs.

Answer 2

If you are thinking of compact flourescent bulbs, it is easy to tell by checking on the packaging; the equivelent ratings are listed prominently.  

Check for deals - places like Home Depot, and Lowes, as well as Menards, typically offer 4 and 6 pack packages of bulbs that are considerably cheaper than buying them individually.

Answer 3

while your getting your cfl bulbs which i got all of my money back  in as little as 2 months in savings on my electric. look at the low water flow heads for showers & sinks, they are high pressure heads that use alot less water but it feels just the same. also sold my suv & bought a prius nafter payment & filling with gas for a month i still have an extra $150.00 left over. my son & i drove the prius from ohio to panama city fla for a week & back & only spend 120.00 0n gas at $3.00 per gallon.

Answer 4

100 watt incandescent light  bulb would be a 26 watt CFL. Yea do change them from the incandescent light because it uses less energy. I spend $120 dollars on CFL Light bulbs from walmart last month. I changed out all the incandescent light bulbs in my house to the CFL. Even though you are spending a lot, you will paying saving over a period of time. CFL uses 75% less energy.

Make sure the light bulb package have the energy star on it. I have the GE brand CFL bulbs and it is even brighter than the old incandescent light

Answer 5

Sure.  

Now if you're comparing an incandescent (gets real hot when it's running) light bulb to a CFL, multiply the CFL's watts by 4 to get a decent comparison. So a 13 watt CFL is like a 52 watt incandescent.   It would be less bright than a 100 watt incandescent.   I like light, so I'd go for a brighter CFL as long as it fits in the fixture.  They also make fixtures made for fluorescents.

Answer 6

You will find that a 100W light bulb will correspond to a 20W energy efficient light bulb, thus saving 80% of the energy.
