If you cant see spending what it costs for an LED replacement now, at least switch to a CFL to reduce your costs for one bulb life of about years and then reevaluate the situation then. It will reduce the amount of mercury that is released into the environment and reduce power demands.
Light for remote areas and porle generatorsbecause of the low power requirement for LEDs, using solar panels becomes more practical and less expensive than running an electric line or using a generator for lighting in remote or offgrid areas. LED light bulbs are also ideal for use with small porle generators which homeowners use for backup power in emergencies.
CFLs are sensitive to frequent on/off cycling. Their rated lifetimes of , hours are reduced in applications where the light is switched on and off very often. Closets and other places where lights are needed for brief illumination should use incandescent or LED bulbs.
The screwin torpedoshape and the smallbase of this bulb is designed for smaller light fixtures throughout the house, from chandeliers to sconces. To use a smaller candelabrabased bulb in a regular socket, you can use a socket reducer.
Designed for bathroom vanities or anywhere a globe bulb is required, these bulbs produce light equivalent to a watt incandescent bulb, yet only consume watts of power. Dimmable from to , these bulbs have a degree beam angle to cast light in a wide area.

Most LED bulbs in use today are clear or white bulbs, commonly available in cool or warm white light. But LEDs are also available in s and used as inidual bulbs, or in clusters, for special applications.
Available in MR pin base, LEDs are ideal for track lighting. LEDs do not contribute to heat buildup in a room because no matter how long they remain on, they do not get hot to the touch. Also, because they are more efficient than incandescents, and last times longer than CFLs, the frequency of changing bulbs is greatly reduced.
Choose between warm and cool light new LED bulbs are available in cool white light, which is ideal for task lighting, and warm light commonly used for accent or small area lighting.
White The most popular of the LED s. It produces a soft white light, without harsh reflection, glare or shadows.
Costeffectivealthough LEDs are initially expensive, the cost is recouped over time and in battery savings. LED bulb use was first adopted commercially, where maintenance and replacement costs are expensive. But the cost of new LED bulbs has gone down considerably in the last few years. and are continuing to go down. Today, there are many new LED light bulbs for use in the home, and the cost is becoming less of an issue. To see a cost comparison between the different s of energysaving light bulbs, see ourLight Bulb Comparison Charts.
When to turn off your lights The operating life of a bulb is affected by how many times the light is switched on and off. Here are some guidelines to help you get the peak benefit from your light bulbs.
Mercuryfree no mercury is used in the manucturing of LEDs.
These CFLs have more tubing in a smaller area, which generates even more light in a shorter bulb. They pack high light output into a very small space and can be used in fixtures designed for incandescent bulbs, such as le lamps, reading lamps, open hanging lamps, and bare bulb applications.

call your local recycling center to see if they accept this material, otherwise put it in your local trash. Wash your hands afterward.
CFLs are not spot lights. Retail store lighting usually requires narrow focus beams for stronger spot lighting. CFLs are better for area lighting.
Choose high quality bulbs or they will die prematurely do not buy cheap bulbs from eBay or discounters. They are inexpensive because the bulbs use a lowquality chip which ils easily.
CFLs are simply miniature versions of fulld fluorescents. They screw into standard lamp sockets, and give off light that looks similar to the common incandescent bulbs not like the fluorescent lighting we associate with ctories and schools.
Lumen output LED vs CFL vs incandescent
LEDs are now available for standard recessed lighting pots and housings. They range from . to watts, with beam widths from PAR to PAR. Several models are dimmable. Also, because they are more efficient than incandescents. and last times longer than CFLs, the frequency of changing bulbs is greatly reduced.
Light Emitting Diode LEDandCompact Fluorescent Lights CFLbulbs have revolutionized energyefficient lighting.
RedRed is the traditional for maintaining night vision. Some LED headlamps and flashlights have the option of switching to red light for use at night.
Match lumensto the incandescent being replaced. Lumens indicate the amount of light being generated. Watts is a measure of energy use, not light strength. Lumen output is printed on the bulb package or on the bulb product if purchasing bulbs online.
Many different models and s of LED bulbs are emerging in todays marketplace. When choosing a bulb, keep in mind the following

Mercury is a toxic metal associated with contamination of water, fish, and food supplies, and can lead to adverse health affects. A CFL bulb generally contains an average of mg of mercury about onefifth of that found in the average watch battery, and less than /th of the mercury found in an amalgam dental filling. A power plant will emit mg of mercury to produce the electricity to run an incandescent bulb compared to only .mg of mercury to run a CFL for the same time. The net benefit of using the more energy efficient lamp is positive, and this is especially true if the mercury in the fluorescent lamp is kept out of the waste stream when the lamp expires.

Designed to replace incandescent candelabra bulbs, these flame tip LEDs deliver the equivalent light of watt incandescents while only drawing . watts of electricity. Because of the heat sink in the base, light doesnt disperse downwards as much as a typical incandescent candelabra bulb.
The chart below shows the amount of brigthness in lumes you can expect from different wattage light bulbs. The LED bulbs require much less wattage than the CFL or Incandescent light bulbs, which is why LED bulbs are more energyefficient and long lasting than the other s of bulb.
Luminous Flux the flow of light measured in lumens. With light bulbs, it provides an estimate of the apparent amount of light the bulb will produce. Depending on the application, much of an incandescents light is wasted because its emitted in every direction. LED bulbs, on the other hand, put out directional light, sending all of the light exactly where its needed.

A significant feature of LEDs is that the light is directional, as opposed to incandescent bulbs which spread the light more spherically. This is an advantage with recessed lighting or undercabinet lighting, but it is a disadvantage for le lamps. New LED bulb designs address the directional limitation by using diffuser lenses and reflectors to disperse the light more like an incandescent bulb.
Comparing the Cost/Benefits of LED vs CFL vs Incandescent Light Bulbs
The high cost of producing LEDs has been a roadblock to widespread use. However, researchers at Purdue University havedevelopeda process for using inexpensive silicon wafers to replace the expensive sapphirebased technology. This promises to bring LEDs into competitive pricing with CFLs and incandescents. LEDs may soon become the standard for most lighting needs. We are following these developments with interest and will report thelatest updatesin this research.
Dimmable CFLs are available for lights using a dimmer switch, but check the package;
CFLs contain small amounts of mercury which is a toxic metal. This metal may be released if the bulb is broken, or during disposal. For more information about mercury and CFLs, see below.
Estimate desired brightness read the package to choose desired brightness level. You can use wattage to compare bulb illumination, for example, a W LED is equivalent in output to a W incandescent. However, the new method for comparing bulbs is lumens. Lumens is the measuse of perceived brightness, and the higher the lumens, the brighter the bulb. The FTC has mandated that all light bulb packages lumens as the primary measure for comparing bulbs. For more information about lumens, see LED Terminology further down this .
Cool these bulbs do not cause heat buildup; LEDs produce . btus/hour, compared to for incandescent bulbs.Common incandescent bulbs get hot and contribute to heat buildup in a room. LEDs prevent this heat buildup, thereby helping to reduceair conditioning costs in the home.
While lumens is the best measurement of comparative lighting among the various bulbs, it is not always a perfect measure. Some floodlights in can lighting use an internal reflector in the bulb to send the light cing downward. When shopping for light bulbs, note that bulbs equipped with reflectors will deliver increased directional light.
Lumen a unit of standard measurement that is used to describe the amount of light contained in an area as perceived by the human eye. The more lumens, the brighter the light. You can use lumens to compare the brightness of any bulb, regardless of the technology behind it, and regardless of whether its incandescent, CFL or LED.
These bulbs are designed as a continuous tube in a spiral shape which has similar outside shape and light casting qualities to a standard incandescent bulb.Spiral CFL bulbs are made in several s to fit most common fixtures.
These lamps are designed to be ideal for recessed and track lighting fixtures, indoors and outdoors. They provide diffused, soft, white light, and generate less heat than will an incandescent flood or a halogen bulb. CFL flood lamps are available in varying s and wattages.
Blue Many people like the blue because it is very easy on the eyes. Blue appears to be a good reading light for elderly eyes. Elderly folks report that they can read under the blue light for hours without eyestrain, compared to severe eyestrain in less than minutes with incandescent lighting.
The mercury in compact fluorescent bulbs poses no threat while in the bulb, but if you break one
Less ExpensiveAlthough initially more expensive, you save money in the long run because CFLs use / the electricity and last up to times as long as incandescents. A single watt CFL used in place of a watt incandescent will save about kWh over its lifetime. At cents per kWh, that equates to a savings.
CFL bulbs have a Kelvin or K number listed on the packaging. CFLs with K numbers between give off a soft bright light like incandescents. CFLs with K numbers between give off a bright light. As you go up the K number scale the light gets bluish and closer to daylight.
Burned out CFLs can be dropped off at Home Depot and Ikea stores. Another solution is to save spent CFLs for a community household hazardous waste collection, which would then send the bulbs to cilities capable of treating, recovering or recycling them. For more information on CFL disposal or recycling, you can contact your local municipality.
Designed to replace fluorescent tube bulbs, these LED tubes are available in and watts, which replace traditional watt and watt T/T/T fluorescent tubes. Because fluorescent lights are often installed in high ceilings in commercial sites, there are additional savings because the frequency of changing bulbs is greatly reduced.
In this LED bulb, clusters of LEDs are covered by a dimpled lens which spreads the light out over a wider area. Available in standard Edison bases, these bulbs have many uses, such as area lighting for rooms, porches, reading lamps, accent lamps, hallways and lowlight applications where lights remain on for extended periods.
This shape is commonly used in bathroom vanity mirrors or open hanging lamps, and bare bulb applications. Bathroom vanities usually require multiple bulbs, which generate radiant heat. The CFL globe will reduce this heat buildup while saving energy. The glass diffuser provides a softwhite light.
not all CFLs can be used on dimmer switches. Using a regular CFL with a dimmer can shorten the bulb life span.
are solid light bulbs which are extremely energyefficient. When first developed, LEDs were limited to singlebulb use in applications such as instrument panels, electronics, pen lights and, more recently, strings of indoor and outdoor Christmas lights.
In practical application, when buying a light bulb, we should look for bhlbs which produce more light but consumes less energy. Understanding lumens as a measure of brightness makes it easier to select the most efficient bulb for your application. This is also important
Choose between standard and dimmable bulbs some LED bulbs, such as theSwitch, LEDnovation and FEIT LED bulbs, are now available as dimmable bulbs. They will work on your standard dimmer switch.
Coloring Rendering Index CRI CRI represents the quality of light and its ithfulness to render s correctly, that is, to enable us to perceive s as we know them. The ideal CRI is , and some incandescent bulbs approach this level. LEDs and CFLs use different design components in trying to equal the CRI of incandescent bulbs. LED bulbs CRI ratings range from to , and the best CFLs have ratings in the mid s. The LEDCREE CR bulb, for example, features a CRI of Warm White it one of the highest in the industry.

Energyefficient CFLs can be used in recessed fixtures, le lamps, track lighting, ceiling fixtures and porchlights. way CFLs are also now available for lamps with way settings. Dimmable CFLs are also available for lights using a dimmer switch.
Although CFLs are an excellent source of energyefficient lighting, they are not always the best choice for all lighting applications. Here are a few limitations to consider
Manucturers have expanded the application of LEDs by clustering the small bulbs. The first clustered bulbs were used for battery powered items such as flashlights and headlamps. Today, LED bulbs are made using as many as bulbs per cluster, and encased in diffuser lenses which spread the light in wider beams. Now available with standard bases which fit common household light fixtures, LEDs are the next generation in home lighting.
CFLs are available in a variety of s or shapes. Some have two, four, or six tubes. Older models, and specialty models, haveseparate tubes and ballasts.Some CFLs have the tubes and ballast permanently connected. This allows you to change the tubes without changing the ballast. Others have circular or spiralshaped tubes. In general, the or total suce area of the tube determines how much light the bulb produces.
