are they still making cfl bulbs?

GE just announced that it no longer make or sell compact fluorescent lamp (CFL) lightbulbs in the US. The company will wind down the manufacturing of CFL bulbs by the end of 2016, and it will begin to shift its focus on making the newest and most energy-efficient lightbulbs, LEDs. This is good news for a few reasons.

The answer is a resounding NO! They are not outdated. Maybe the term 'sconce' is considered old in some circles, but wall lighting as a home decor category is as big as ever.

CFLs produce light differently than incandescent bulbs. ... In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible light.

Compact fluorescent light bulbs (CFLs) use dramatically less energy than incandescent bulbs and reduce greenhouse gas emissions. But they also contain mercury – a dangerous toxin. ... If a CFL breaks, some of the mercury that's contained in the bulb will evaporate into the air.

Top positive review 5.0 out of 5 starsFantastic lighting and a little brighter than a normal 60w bulb. Fantastic alternative to regular light bulbs, and none of the harmful side effects of the CFL's. Great output of light, they actually seem brighter than my old 60w light bulbs and they'll save me money.

Yes, but with some qualifications. The life of CFLs will be reduced if they are operated at higher than normal temperatures. Therefore, they can be used in totally enclosed fixtures, including vapor-tight fixtures, as long as you do not use a high power CFL, and the temperature outside the fixture is not too high.

Just aim for about 150W of CFLs in Total Per Plant to Start, and stick to relatively smaller size bulbs if you can! If you want them to screw into regular light bulb sockets, use ones with a “medium base”.

The government has prohibited manufacture and import of all incandescent lights. All incandescent bulbs are going to be replaced by LED and CFL light bulbs.

Since CFLs are designed to provide general illumination, the majority of the light emitted by CFLs is localized to the visible region of the spectrum (approximately 400-700 nm in wavelength). In addition, typical CFLs emit a small amount of UVB (280-315 nm), UVA (315-400 nm) and infrared (> 700 nm) radiation.

Longevity—With an average lifespan of approximately 10,000 to 15,000 hours, a CFL bulb lasts about ten times longer than an incandescent bulb—which means they need to be replaced less often, making them convenient for those hard-to-reach light fixtures and lamps.

There are three main types of regular light bulb – CFLs (compact fluorescent lamp – the standard type of energy-saving light bulb), halogens or LEDs.

Incandescent bulbs and halogen bulbs have the highest wattage, making them less energy-efficient choices. CFL bulbs use fewer watts, but LED bulbs are the real winner in energy efficiency—an 8 or 9-watt LED bulb emits as much light as a 60-watt incandescent bulb.

All compact fluorescent (CFL) bulbs require a ballast, which is often integrated. All HID bulbs require a ballast, which is sometimes integrated. No LED bulbs require a ballast, although some are engineered to work with an existing ballast.

CFLs are highly versatile and can be used in any setting where you would normally use incandescent bulbs. They come in enough shapes and sizes that you can use them for recessed fixtures, table lamps, track lighting or ceiling lighting. Three-way CFLs and CFLs that work with dimmers are also available.

Advantages of CFLs You can replace a 100-watt incandescent bulb with a 22-watt CFL and get the same amount of light. CFLs use 50- to 80-percent less energy than incandescent lights. While initially they cost more, CFLs are less expensive in the long run because they last much longer than incandescent bulbs.

Compact fluorescent lamps (CFL), commonly known as energy-saving lamps are identified by their fluorescent tube bent onto itself or even wrapped. These bulbs use less energy than traditional incandescent bulbs, they contain mercury, a substance that can be harmful to humans and to the environment.

On January 1, 2014, in keeping with a law passed by Congress in 2007, the old familiar tungsten-filament 40- and 60-watt incandescent light bulbs can no longer be manufactured in the U.S., because they don't meet federal energy-efficiency standards.
