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 and fittings - LEDs are available in several types of 'pin' sockets or the standard "screw' bases for recessed or track lighting.
Choose between standard and dimmable bulbs - some LED bulbs now available as dimmable bulbs.

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

Diffused bulbs
In this style LED bulb, clusters of LEDs are covered by a dimpled lens which spreads the light out over a wider area. These bulbs have many uses, such as area lighting for rooms, porches, reading lamps, accent lamps, hallways and low-light applications where lights remain on for extended periods.

Diffused high power bulbs
Designed for standard household use, these bulbs produce light equivalent to a 100-watt incandescent bulb.

Track Lighting
Available in pin base or standard 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.

Recessed Downlight and Spotlight bulbs
LEDs are now available for standard recessed lighting pots and housings. The light output and color quality are similar to incandescent downlights, but draws only about one-fifth of the power. Also, because they are 90% more efficient than incandescents. and last 10 times longer than CFLs, the frequency of changing bulbs is greatly reduced.

Spotlight and Floodlight LEDs
The spotlight LED lacks a dispersing lens, so it appears brighter as its light is directed forward. It runs cool and will last over 50,000 hours due to advanced thermal management design. The floodlight model gives a spread-out dispersed light. Well suited for ceiling lights, outdoor floodlights. retail display lighting, landscape lighting and motion sensors.
