The amount of light produced by any light bulb is measured in "lumens." The lumen rating is always listed on the packaging and/or in the catalog. You can directly compare the rated output of the CFL versus the rated output for the familiar incandescent bulb that you're replacing. The light output of a CFL falls off somewhat, very gradually, over the long life of the bulb.

The primary difference is in size; compact fluorescent bulbs are made in special shapes (which require special technologies) to fit in standard household light sockets, like table lamps and ceiling fixtures. In addition, most compact fluorescent lamps have an "integral" ballast that is built into the light bulb, whereas most fluorescent tubes require a separate ballast independent of the bulb. Both types offer energy-efficient light.

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.

To use a compact fluorescent bulb on a dimmer switch, you must buy a bulb that's specifically made to work with dimmers (check the package). GE makes a dimming compact fluorescent light bulb (called the Energy Smart Dimming Spirals®) that is specially designed for use with dimming switches. We don't recommend using regular compact fluorescent bulbs with dimming switches, since this can shorten bulb life.

GE does make CFL bulbs for use in 3-way lamps. Check the package for this application. If a regular CFL is use in a 3-way switch, it will work on the middle (medium) setting and it should not damage the bulb. The 3-way switch does not alter the performance of the bulb.

Some electronic timers and photocells contain parts that are incompatible with compact fluorescent light bulbs; using these bulbs in incompatible products will result in a shorter light bulb life. To find out if an electronic timer or photocell is compatible with compact fluorescent bulbs, check with the manufacturer of the timer or photocell. Yes. CFLs, when compared with standard incandescent bulbs, offer many benefits. First, they help save energy and money.

The first compact fluorescent bulbs flickered when they were turned on because it took a few seconds for the ballast to produce enough electricity to excite the gas inside the bulb. Thanks to the refined technology in our new GE compact fluorescent bulbs, there is now no significant flicker (less than 1 second). However, these bulbs do require a short warm-up period before they reach full brightness, which is why they may appear dim when first turned on.

The electronic pre-switch system of the lamp contains a rectifier with a post-switch smoothing condensor (Elko). The Elko is always charged to the highest value of the alternating current, the mains current flowing quickly towards and as far as the maximum mains voltage. This configuration prohibits the operation of dimmers available in the trade as phase on and off dimmers damage the Elko due to their steep voltage gradient.

Energy saving light bulb 20W is 1200lm, and the light power of a 100W bulb is 1380 lm. From it you can see that the compact fluorescent light bulb 20W with in light power would be approximately equivalent to a "87W light bulb". bulbs of this performance level are not available on the market, it was decided to select for the pictogram on the outer packaging the nearest possible comparable output level in light power of conventional bulbs.

Fluorescent light bulbs (including compact fluorescents) are more energy-efficient than regular bulbs because of the different method they use to produce light. Regular bulbs (also known as incandescent bulbs) create light by heating a filament inside the bulb; the heat makes the filament white-hot, producing the light that you see. A lot of the energy used to create the heat that lights an incandescent bulb is wasted.

Compact fluorescent lamps with integrated electronic pre-switch systems do not contain radioactive constituents. (such as, for example, Krypton 85), also do not contain radioactive substances. This also applies to the appropriate electronic pre-switch system.

No. . compact fluorescent light bulbs have been designed to produce warm, pleasing light. You'll find it similar to our soft white bulbs.

Usually, 5W to 11W E27 and 5W to 7W E14 can be operated on a direct voltage between 176V to 340V besides the usual alternating power usage. This means, for instance, compact fluorescent light bulb may be operated with battery supplied 220/230V facilities in internal areas. At the lower limit of 176V the lamps will light perfectly in a environment with a temperature of 5°C to 50°C. They are not sensitive to over-voltages of the direct current grid up to 340V.

These lamps are discharge lamps with an electronic pre-switch system which operates with an operating frequency between 30 und 45 kHz depending on type of lamp. With it also higher frequency upper wave lengths are produced that are being dampened by transmitter non-interference filters so that the issued legally prescribed border values and cable associated interferences are in no way exceeded.

Compact fluorescent lights save you approximately 75% of the energy and last 10 times longer than a comparable incandescent light bulb. For more information, request our "Home Lighting" brochure.

CFL technology has several advantages over incandescent lighting technology: it is four times more efficient and lasts up to 10 times longer, it uses about 75% less energy, and produces 90% less heat while delivering more light. In addition, they provide a flicker-free start, soft-white light, are environmentally friendly, and come in a variety of styles. Click here to go to the CFL section.

Like paint, batteries, thermostats, and other hazardous household items, CFLs should be disposed of properly. Do not throw CFLs away in your household garbage if better disposal options exist. To find out what to do first check www.earth911.org (where you can find disposal options by using your zip code) or call 1-877-EARTH911 for local disposal options. Another option is to check directly with your local waste management agency for recycling options and disposal guidelines in your community.

They come to be accepted by degrees, by precedent, by implication, by erosion, by default, by dint of constant pressure on one side and constant retreat on the other - until the day when they are suddenly declared to be the country's official ideology.

If a light breaks, put on protective gloves and carefully sweep up all of the glass fragments and any powder with a disposable hand broom and dust pan. Place the broken pieces of glass in a rigid food storage container with a snap on lid. Place the disposable hand broom and dustpan in a plastic bag and wipe the area with a damp paper towel. Put the used towel in the plastic bag as well and then place everything in a five-gallon bucket or container with a lid.

While a regular (incandescent) light bulb uses heat to produce light, a fluorescent bulb creates light using an entirely different method that is far more energy-efficient - in fact, 4-6 times more efficient. This means that you can buy a 15-watt compact fluorescent bulb that produces the same amount of light as a 60-watt regular incandescent bulb. Plus fluorescent light bulbs last up to 13 times longer and use 2/3 to 3/4 less electricity than incandescent bulbs with similar lumen ratings.

If you used a lamp in the evening from 5 p.m. until 11 p.m. - every day of the year - the lamp would produce beautiful, warm light for more than four and one-half years!

A - Yes. With the cost of electricity going up dramatically, all incandescent lamps that operate for more than three hours a day should be replaced with CFLs. Fortunately, the prices of CFLs have been coming down dramatically. CFLs equipped with electronic ballasts can now be purchased for less than $10.00 in many locations. CFLs are three to four times more efficient than incandescent sources and last many times longer.

The white powder that you see inside a fluorescent lamp is called phosphor, which is a substance that emits white, visible light whenever it absorbs light waves. Both compact fluorescent bulbs and fluorescent tubes contain a gas that gives off invisible light when excited by electricity. This invisible light travels to the phosphor coating on the bulb, where it is transformed into light visible to the human eye.

Puncture resistant gloves are recommended for cleaning up broken glass. After picking up all large fragments, wipe area thoroughly to clean any remaining glass or phosphor residue. If necessary, ventilate area to remove any remaining fine phosphor dust. After handling broken lamps, wash hands and face thoroughly. Incidental exposure to lamp contents is not harmful. The basic phosphor used in the manufacture of fluorescent lamps is a relatively inert phosphate.
