6 Myths about CFL’s

CFL’s are becoming more popular every day, but there are still a ton of myths about them. Let’s take a look at the big ones:
- They flicker - The really old CFL’s did flicker, and they were terrible. Fortunately modern day CFL’s have resolved this issue, and they don’t flicker at all.
- They produce unnatural “alien” light – CFL’s are available in a huge range of light colors – from yellowish to bluish-white, depending on your preference. If you get the yellowish color, you can’t tell the difference between CFL and incandescent.
- They aren’t as bright as regular light bulbs – Not so. You just need to make sure you match up equivalent lumens ratings. Replacing a 100W bulb with a 13W CFL won’t give off the same light. You’ll need a 23W CFL.
- They hum – Same as the flickering issue – long gone.
- The mercury inside is a health hazard – CFL’s do contain mercury, there’s no doubt about it. It’s a very tiny amount though; about 1/5 the amount in a watch battery. In other words, not enough to do any harm, unless you break a bunch.
- They’re expensive – CFL’s do cost more than regular bulbs up front. But they are readily available for well under $2 per bulb these days, and you’re likely to make up that cost in less than a year with energy costs alone. When you figure that CFL’s last much longer than regular bulbs, you end up way ahead of the game.
The bottom line is this – CFL’s are a no brainer. They will save you money each and every month, with no inconvenience to you. If you’re serious about saving money, then you need to jump on the CFL bandwagon. Oh, and as an added bonus – they’re better for the environment. Since CFL’s use a quarter or so of the energy as a regular bulb, they contribute much less pollution to the environment. I’m no treehugger, but hey I’m not against helping save the world either, especially if I can save money at the same time.

CFL’s are fantastic. They save a lot of money in the long term and are insurance for our environment (sort of a tree hugger, myself). I do think that the mercury is a concern and there should be more recycling programs put in place now that the word is out and people are using CFL’s more. We’ve been using them for about 10 years and in the beginning, the problems you mentioned were there but they are no longer a problem. The ones they are selling now have come a long way.

Good points. A couple of years ago we switched all the light fixtures in our house to CFLs.
The power bill went down $25 month. Some of that might have been from updating the wiring in the house, but I’m sure a lot of it came from changing to CFLs.

I finally got my mother-in-law to replace all her bulbs in her house, and she could not believe how much her power bill went down. I wanted to say “Told ya so!”…but I refrained.

Congrats on getting her to make the switch David! It’s very hard to overcome other people’s misconceptions about CFL’s. The old ones were pretty bad, we have to admit.

I just replaced my incandescent bulbs with CFL’s in a location with a dimmer switch (the intent is to test, then swap the dimmer with a regular switch). After initially turning them on, everything is great. Now, after 24hrs, they flicker. I haven’t had a chance to swap the switch yet – could that be why? Ideas?
Thanks

I think that most dimmers do their job by taking household current and sending less of that current to the light. What doesen’t get sent to the light is wasted in the form of heat. Now the new dimmers may achevr there effect in a different manner, I know the old ones had a finned heat sink on the backside. So if you use them with cfl’s the ballest in the base is not getting the proper amount of current. This may cause the flicker. Also there will be a reduced effect on the electric used because some is being wasted at the dimmer.
