How to choose an LED light bulb

 
 
LED light bulbs will eventually be what we use to replace incandescent bulbs – CFLs are a temporary solution to energy-efficient lighting. The reason LEDs have not yet displaced CFLs from the market are twofold: the first generation LED bulbs had a narrow and focused light beam, and the cost of the LED bulbs was too high.

Recent developments in LED technology, however, have been addressing these issues. LEDs have been 'clustered' to provide more light, and mounted within diffuser lenses which spread the light across a wider area. And advancements in manufacturing technology have driven the prices down to a level where LED bulbs are more cost-effective than CFLs or incandescent bulbs. This trend is continuing, with LED bulbs being designed for more applications while the prices are going down over time.

The 'sticker shock' of the new LEDs remains a deterrent to their widespread acceptance by consumers. The following comparison charts illustrate the value of the latest LED bulbs when compared with CFLs and incandescents for overall efficiency as well as cost-effectiveness.

Notes:
- Cost of electricity will vary. The figures used above are for comparison only, and are not exact. Residential energy costs among the various states range from 28.53 cents (Hawaii) to 6.34 cents (Idaho) per KWH.
- The cost per bulb for LEDs may vary. We used the figure of $35.95 (for a 60 watt equivalent LED bulb) as an average among lighting retailers.
-
Estimates of bulb lifespan are projected, since it would take about 6 years of continuous lighting to test. Some manufacturers claim the new LED bulbs will last up to 25 years under normal household use, but this is not proven.
- Bulb breakage and bulb replacement costs have not been factored into this comparison chart. Incandescent bulbs and CFL bulbs are more easily broken than LEDs, which increases their cost of use.
- Most LEDs come with a minimum 2-year guarantee. Any defective LED bulb will usually fail within this time.

Notes:
- Dimmable LEDs cost about 40% more than non-dimmable LEDs of similar wattage.
- Estimates of bulb lifespan are projected, since it would take about 6 years of continuous lighting to test. The FEIT bulb life expectancies are considerably understated. Some manufacturers claim the new LED bulbs may last up to 25 years under normal household use.

Terms:
- Lumens - The unit of measurement of the flow of light, or 'luminous flux'. With light bulbs, it provides an estimate of the apparent amount of light the bulb will produce.
- Coloring Rendering Index (CRI) . CRI represents the quality of light and its ability to render colors correctly. The
SWITCH dimmable 12 watt warm white, for example, features a CRI of 80 making it one of the highest in the industry.

Choosing an LED light bulb
 
Many different models and styles of LED bulbs are emerging in today's marketplace. When choosing a bulb, keep in mind the following:


• Estimate desired wattage - read the package to choose desired illumination level. For example, a 3W LED is equivalent in output to a 45 W incandescent.
• 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.
• Standard base or pin base - LEDs are available in several types of 'pin' sockets or the standard "screw' (Edison) bases for recessed or track lighting.
Choose between standard and dimmable bulbs - some LED bulbs, such as the SWITCH Electric bulbs, are now available as dimmable bulbs.

The common styles of LED bulbs available for household use include the following:

 LED Diffused bulb
Omnidirectional LED bulbs
In this style LED bulb, clusters of LEDs are covered by a lens which spreads the light over a wider area, like standard incandescent bulbs. Available in standard Edison bases, these bulbs are used as area lighting for rooms, porches, reading lamps, accent lamps, hallways and low-light applications where lights remain on for extended periods.
Available in 40, 60 75, 100 watt equivalent; clear or frosted.
Diffused LED bulbs
LED Dimmable Globe bulb

Dimmable Globe LED bulbs

Designed for bathroom vanities or anywhere a globe bulb is required, these bulbs produce light equivalent to a 40-watt incandescent bulb, yet only consume 10 watts of power. Dimmable from 100% to 10%, these bulbs have a 200 degree beam angle to cast light in a wide area.

LED track light bulb
Track Lighting
Available in pin base or standard (Edison) 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 90% more efficient than incandescents, and last 10 times longer than CFLs, the frequency of changing bulbs is greatly reduced.
Track Lighting pin-base LED bulbs
LED Flood Reflector bulb
Flood Reflector LEDs for Recessed Cans and Track lights, screw-in base
LEDs are now available for standard recessed lighting pots and housings. They range from 7.5 to 17watts, with beam widths from PAR20 to PAR38. Several models are dimmable. Also, because they are 90% more efficient than incandescents. and last 10 times longer than CFLs, the frequency of changing bulbs is greatly reduced.

LED Flame Tip Candelabra

Flame Tip, Candelabra Base LEDs

Designed to replace incandescent candelabra bulbs, these flame tip LEDs deliver the equivalent light of 25 - 35 watt incandescents while only drawing 3.5 watts of electricity. Because of the heat sink in the base, light doesn't disperse downwards as much as a typical incandescent candelabra bulb.
LED tube bulb

LED Tube Lights

Designed to replace fluorescent tube bulbs, these LED tubes are available in 8 and 16 watts, which replace traditional 25-watt and 40-watt T8/T10/T12 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.
