Compact Fluorescent

CFL bulbNow that I'm a home-owner, an energy-conscious one even, I thought it was time to start moving to Compact Fluorescent. However, it seems that there are three drawbacks to CFL that currently prevent me from widespread adoption of these bulbs in my house, in order of importance to me:

  • Dimmable - I like to be able to create a nice atmosphere in my home at night and currently almost every lamp and chandelier has either a dimmer or a three-way bulb in them. Even the halogen spots that I own use either 110V dimmers or special transformer dimmers.

  • Color - The color temperature of the bulbs is not the nice yellowish 3000K color that I have come to expect from my table lamps to create an inviting atmosphere in the evening.

  • Warm-up - It seems CFL bulbs take up to a minute to warm up to their final strength and color, and a lot longer when it's colder than room temperature.


I replaced the outside porchlight and the garage light with CFL, but at this point I cannot see myself adopting CF more in my home.

My question is: Am I just not informed enough? Are there CFL bulbs that do not have the aforementioned downsides? I would definitely like to switch but not at the expense of my comfort.

You can get full spectrum CFL, for about $5 a bulb. I prefer full spectrum to yellow bulbs.

We use the CFL bulbs in places like the kitchen, laundry room, bathrooms, playroom, kids rooms.

I use full spectrum bulbs in other places where I spend a lot of time.

A quick google shows that you can get get dimmable CFLs.

Also, the warm up time, you get used to it, I don't really notice. It's not nearly as bad as the warmup on a florescent tube.

Yeah, we have dimmable bulbs in our kitchen. They do take a while to warm up, and the color we've had to get used to. But they do exist!

Can you point me to some models that you use or sites that sell them?

Full spectrum I think is "really white". Are they similar to the "reveal" incandescent series that GE makes? We don't like those, they are too blue.

I really like low color temperatures...

Yea, the blue lights. They make me happy.

Maybe buy some gel and tint your bulbs?

What she said. If you want the full-spectrum, look for 5000K+ color on the package. I like the light those give off the best. But there are the yellowish ones too.

I didn't know that there were dimmable one, but I replaced the few dimmers we had in the house with regular switches. It just wasn't that big a deal, and I almost always kept the light on full anyway.

You can find ones that are instant-on, but it may take a little searching.

The biggest drawback for us is that those motion-sensing light switches will not work with CFs. They work fine with regular tube-fluorescents, just not with CFs. I keep wanting to replace the bathroom light switch with a motion sensor, as the kids keep leaving it on, but the two that I tried just don't work well.

But all in all, I'm very happy that I switched to CFs. Our electric bill dropped by $5-$10/month, and they paid for themselves in 6 months. There's a secondary effect in the summer, as your air conditioner no longer has to work to remove the heat generated by the light bulbs.

Agreed. The dimming inability (with the ones we got anyways) just irritates me back to normal bulbs. I pondering seeing if there are LED lights that would work. It would make for some interesting lighting effects too as you can use different colors. I assume dimming would be done through turning off a number of the LEDs etc.

There was just something on NPR (Well, on public radio and I think it was NPR) about how these are all very known and adoption stopping issues that the industry knows about. Some CFL expert spoke about how the fixes to all these problems are in the pipes, but the bulbs are super spendy now but are coming down quickly.

Sorry for not having more info, but I was driving at the time. :)

You could do a compromise/mixed approach, e.g. fluorescent in places like kitchen, bathroom, garage, and traditional light in den, bedroom. Office could have mixed, e.g. fluorescent ceiling light for overall room light, plus a smaller traditional standing or desk lamp to highlight what you're working on.

If some of your light fixtures have multiple sockets (such as ceiling fans, chandeliers, or bathroom lighting) then you can install a mix of bulbs within the fixture. This lets me have immediate incandescent lighting when I flip the switch, with some CFL bulbs to provide greater brightness. It's at least slightly better than filling the fixture with entirely incandescent bulbs.
