ITS TRUE! ( if you live in a town that does this) AN JUST BY CHANGING A LIGHT BULB! Since it uses less power it will save you money AND help the environment.

### Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

## Step 1: Materials

a lamp with an incandescent.
your local PUD or energy supplier, got them and see if they do a program for energy saving, mine did and hey gave us 2 boxes of cfl's, in each box it had 2 smaller oxes with 6 cfl's in it! thats a total of 24 FREE cfls and as they burn out, they give you more!

## Step 2: Unscrew the Old, Screw the New

Take out your old bulb, and screw in a nice new cfl!

## Step 3: How Does This Help?

well CF's use less power than normal light bulbs, heres that math to prove it

64 Watts Incandesant
14 Watts CFL
-___
50 Watts of saving!

## Step 4: Savings!

I work art afurniture store, we leave lights on over night to show off lamps, when we switched to cfls we saved about \$250 dollars a month!

at my house we saved about \$100 a month!

Now thats some saving!

thats about half of my electricity bill!

I love the idea of saving money, but CFLs light drives me nuts. It is too artificial, and tests have been done that show fluorescent light causes migraines and general malaise.

Try LED Bulbs. They cost a bit more, but use VERY little power and give off a clean white light. The strobe effect of Florescent lights can be one of the reasons for the headaches. LED's just stay on.

lol one f the points is the cfl's are free, anyway leds do have some strobe as well, l ights cycle at 60 herts or change positive to negative 60 times a second leds are light emitting DIODES, this means they only light if electricity is going in a certain directions do to these affects leds cycle slower, being on for 30 cycles and off for 30 meaning these have more of a strobe affect thats visble. I'm fluent enough with electronics to be an entry level electronic technical, i get my facts from educational books! lol

No because they have a bridge rectifier that takes the 60Hz and transform it to DC power and then it goes to a capacitor to make a pure DC output so the light will not flicker.

yes and the ballast of cfls boosts the frequencyinto the kHz range, nobody can see that flicker.

you may not be able to "SEE" it flicker but your body reacts to it. our bodies are much more sensitive to environment than previously thought.

consider that ANY light during the night, except red light, causes a drop in melatonin production resulting in a loss of sleep quality. Who knew? but it was happening and they're now reporting it. most people respond negatively to High power electric lines, but you can't quantify it. they make me feel jittery and anxious.

Same with CFLs. they bother me. the light is wrong, hurts my eyes and makes me tired at least two hours sooner every night than regular light bulbs.

The newest LED bulbs use AC to DC converters. Only the more expensive bulbs have this. The cheap 15 dollar bulbs don't, but the more expensive 40 dollar bulbs do. This means that they don't flicker. They can use as little as 2 watts per hour of use. It's more cost effective to build your own lights and use an AC to DC "wall brick" to power them. For most comercially available LEDs, every 3 watts worth of diodes puts out the same amount of light as a 60 incandescent bulb. For most households (at least in my area), it would take 10 to 12 months to cover the cost of the homebuilt lights. And more than 2x as long for the pre-built, store-bought bulbs.

i believe that those could be caused by EMI but the light cycling at 60Herts can affect brain patterns(NASA uses blinking lights to simulate night and day in space)

Hehehe... I'm very dubious about some of these claimed studies, I grew up with CFL (parents were eco-conscious before it was fashionable and got the early CFLS- the ones that weighed about 500g each, took ten minutes to warm up and blew after a mere five years) and I've never noticed the light to be bad. The 24W one in my room makes a tiny quiet buzzing sound (that I only hear at 1am while creeping around trying not to wake other people up), but the thing I most notice is the light seems to keep me awake- perhaps because it's closer to daylight than incandescent :D

this reminds me of another dissadvantage of CFLs. the story they tell us is they last SOOOOO long. but I haven't found that to be true. perhaps a year, but no longer. they burn out at almost the same rate as regular bulbs.

Really? I've used them forever and I don't think I've ever had a single one "burn out". The older ones would eventually get a bit dim and take longer to warm up, but they keep working.

Are you using them on a dimmer (bad) or in an area with patchy or noisy electricity supply? That's the only reason I could think of that would make them actually blow that often.

I can believe we have inferior electric service. we live in a large farming community.

from my energy supplier, they do a green program where they set you up with cfl's and give you some if they ever burn out. if your local pud or energy supplier doesn't offer this got a bulk supplier and buy like 24 for about 10-15 usd

please provide studies. I teach lighting and nothing supports this claim. Older fluorescents with magnetic ballasts did cause headaches and fatigue in some people. Newer systems with electronic ballasts do not. thanks.

I agree that they seem to artificial, there is no better lighting than tungsten heated to 3000°C.
