It's pricier than both CFLs and incandescent bulbs, but it lasts longer and has the potential to save you more money over the long haul.

No matter that the savings for American families accruing from moving to CFLs or LEDs will be worth $6 billion a year or more.

Nor do they like the time it takes for these bulbs to reach their maximum illumination.

"CFLs have peaks in the blue, green, and red ranges, so they fall in the middle in terms of spectrum, " explains Lockley.

Though not as widely available (or as affordable) as CFLs, LEDs come as standard bulbs as well as built into lamps and Christmas lights.

The barrels were filled with CFLs and often were open or not properly sealed (see photo).

His twisty tube was a major achievement, so tricky to produce that many CFLs are still curled by hand.

CFL brightness decreases over time, but if you buy higher-watt CFLs they should maintain a higher lumen output for a longer period of time.

They are still made largely in China, but at least most of the former complaints have since been addressed.

CFLs have been around for several years. However. the older lights still make up about two-thirds of total light bulb sales.

Experts predict that the shift in demand will also cut the cost of CFLs and increase the cost of incandescents globally.

Some people prefer the warmer glow of an incandescent bulb to the light produced by CFLs.

CFLs cost three to five times as much as conventional incandescent bulbs yet use one-quarter the electricity and last several years longer.

He has also found that CFLs last longer when used upright in a lamp-stand, rather than dangling from a ceiling fixture.

CFLs use around 75% less energy to produce an equivalent amount of light and last much longer.

Still, there is no denying that, on most other counts, CFLs are a far better choice than incandescents.

The bulbs are estimated to last up to 6, 000 hours, which is comparable to CFLs, and three to four times as long as incandescent bulbs.

Still, the consumer backlash resonates, and not simply because CFLs are horrible, flickery, ugly, and unreliable.

Until now, the main alternative was compact fluorescent lights, or CFLs.

If people want to replace their old power-hungry incandescent bulbs with CFLs or LEDs good for 45 lumens per watt, all the better.

It wasn't until the 1990s that CFLs gained traction, driven by concerns about energy efficiency.

The winning LED lights beat out CFLs in energy savings, using upwards of 80 percent less energy than an incandescent bulb.

CFLs at the time cost roughly $11 each, 20 times the cost of incandescent bulbs.

Turn off incandescents if you're leaving the room for more than five seconds; CFLs, if you'll be gone at least 15 minutes.

Energy Star rated: Energy Star CFLs use 75 percent less energy than standard incandescent bulbs.

The general consensus is that it's best to turn off CFLs when you are leaving for 15 minutes or longer.

Dome-shaped CFLs, similar in look to conventional incandescents, are a better fit for lamps whose shades clip onto the bulb.

Could you reduce that electricity bill by putting in a lot of CFLs?

Tungsten light bulbs are about 5 times less efficient than compact fluorescent lamps (CFLs) and they have a lifetime up to 10 times longer.

CFLs now come in many shapes, sizes and colors that can be used in fixtures such as ceiling fans and chandeliers.

The CFLs will release a monstrous 42 mg of toxic mercury into landfills.

Despite the higher price tag, it sells 137 million CFLs, which use 75% less energy than incandescents.

You can now find LEDs for around $20, while CFLs average from $2-$10.

CFLs and LEDs both come in at about $1. 50 per year.

A good number for incandescents is around 18, CFLs around 60, and LEDs around 54.

A U. S. government survey last year found that only 11 percent of household sockets have CFLs.
