Compact Fluorescent Light Bulbs

Summary: Compact fluorescent light bulbs (CFLs) only use 25 percent of the electricity a wasteful standard incandescent light bulb uses. Some even last a minimum of 7 years. Using less wattage they produce the same glow and amount of light normal bulbs do, but will save you tons of money.

DEAR TIM: I want to conserve and cut down on my electricity usage. During the winter my interior lights are on for long periods of time. I turn lights off and have started to use standard bulbs that are lower wattage. Now it is so dark and dim I feel like I live in a cave. Are those newer compact fluorescent light bulbs (CFLs) as good as advertised? Will they produce enough light? Joanne O., Wenham, MA

DEAR JOANNE: More people need to think like you do. Not only will lots of money be saved but the planet's natural resources will also be conserved for future generations. People need to be constantly reminded that Mother Nature can not create coal, oil and natural gas as fast as we use it. Much of the electricity we consume is generated using these fossil fuels.

These crazy looking bulbs work and they save money. If your family leaves on lights like mine does, you will see a big difference in your electric usage should you replace lots of your ordinary bulbs with these.

Two things work against us during the winter months. Not only are the nights considerably longer, but most people tend to stay indoors out of the cold weather. It is not uncommon for electricity used for indoor lighting to surge 250 percent or more from what you might use in the summer months. Although it is a great idea to save energy on lighting every day, you get the best return on investment in the dead of winter.

The CFLs really save money. In almost all cases, a CFL bulb will only consume 25 percent of the electricity that is gobbled up by a wasteful standard incandescent bulb. Yet the amazing reality is that this smaller wattage CFL bulb produces the same amount of light as a traditional bulb. The color/glow is also exactly the same, so don't worry that the inside of your home is going to have the harsh look of an office building. The CFLs are designed to produce light that is ideal for the inside of the average home.

To achieve savings that you can really see on your utility bill you need to embark on a program to change as many of your traditional bulbs as quickly as possible. For example, the average living room might have two table lamps, possibly two recessed lights and maybe a ceiling fan light. If you replace all of the bulbs in this one room with CFLs, you could easily save close to $32.00 per year. If you do a quick analysis of the remaining bulbs in your home, you might discover that you can save a whopping $260.00 per year.

Another often overlooked benefit of the CFLs bulbs is that they last typically eight to ten times longer than a standard incandescent bulb. This means that year in and year out you will continue to save enormous amounts of money. In fact, some CFL bulb manufacturers guarantee their bulbs to last a minimum of seven years. Simple math shows that a CFL bulb might pay for itself in just replacement costs alone! Add in the energy savings and you can see why 65 percent of the households in Germany use CFL bulbs throughout their homes.

The CFL bulbs are available in a variety of sizes. Not only can you get ones that replace a standard light bulb, you can also get reflective bulbs that are designed to work in recessed light fixtures. Even tiny CFLs are made for candelabra fixtures. If you live in a warmer climate you can confidently use these bulbs in outdoor applications. Cold air temperatures can affect the startup of the bulbs and some CFLs do not work if the temperature drops below 20F.

When you go to buy CFL bulbs you need to pay attention to the wattage of the bulb. Keep in mind that a 15 watt CFL bulb produces the same amount of light as a 60 watt incandescent bulb. Some manufacturers have wonderful packaging that shows you exactly what type of bulb the CFL is replacing. When you get home and turn your CFLs on, they will react like you do when you first get up in the morning. It takes several seconds for them to get up to full brightness. Don't think that the bulbs are defective. Trust me, you are going to have the brightest cave on the block!

I would like to use CFLs in my home to cut costs and to help the enviroment, but I have can lights in my family room and living room and the CFLs I purchased don't fit. The neck of the bulb isn't long enough to allow the bulb to be screwed into the socket.

Also, on some of my light fixtures, the bulbs are too wide to fit under the glass shade.

Are there any options for these situations?

Mike,
You need to talk with the bulb makers for a workaround.

I would like to replace 60watt incandescent chandelier bulbs with compact fluorescents, ideally dimmable, but I would accept non-dimmable. Does anyone make such a bulb?

John,
Check with GE.

It's near impossible to find cfl candelabra bulbs that actually fit most chandeliers. Mine uses a bulb that's 2.5 inches long and all I've found is 4 inches and up in the CFL. Have you heard of any manufacturer who makes the bulb length that I need? ahrwz

If my fixture is labeled limit 40 watt bulb. Can I replace my old 40 watt bulb with one of the cfl bulbs like 23 watt +100 watt to give me more light?

Hi Tim! I am remodeling a new construction basement with recessed lighting. I successfully wired the cans and attached dimmer switches. I attached screw-in fluorescent flood lights to save money. All is up to code and wired correctly. However, the circuit breaker kept tripping upon turning the light switch on. Soon thereafter the switch itself blew and is now non-functional. The lights work fine in the can lights though. I found out that my switch was non-compatible with fluorescent lights so I will change that. Is that why the circuit breaker ws tripping?

But, do the cans accept fluorescents or not? I cannot confirm the answer by reading the package insert from the can lights. They are H7ICT type cans from Halo.

I am fearful that I will not be saving energy or money due to the need for having to possibly use incandescent flood lights only.

Thanks

This is from GE's FAQ on CFLs as of July 2009.

"Compact fluorescent light bulbs may generally be used in enclosed fixtures as long as the enclosed fixture is not recessed. Totally enclosed recessed fixtures (for example, a ceiling can light with a cover over the bulb) create temperatures that are too high to allow the use of a compact fluorescent bulb."

Unfortunately this was true for my IC-rated cans even without them being "enclosed" with a cover over the bulb. (I've never seen cans that have a cover other than a fish-eye. Anyway, in my experience the IC cans tend built up so much heat that the CFLs burn out in under 6 months, so it's back to halogen floods for me.

I also replaced some outdoor halogen floods with CFLs. Again, those were sadly on a motion-detecting switch. GE's FAQ also states that turning a CFL on and off frequently and leaving it on for less than 15 minutes at a time burns it out quicker and negates a lot of the energy efficiency of the bulb. CFLs are great for table lamps, unless you want to use 3-way switches.

Can I use CFL bulbs with recessed lights(pot lights) for a basement?
