Wattages and Light Comparisons
Equivalent wattages and light output of Incandescent, CFL and LED bulbs
Comparing the features of Incandescent, CFL and LED bulbs
Choosing an LED Light Bulb
The common styles of LED bulbs available for household use include the following. 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
• 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
• Choose between standard and dimmable bulbs – some LED bulbs, such as the FEIT Electric bulbs, are now available as dimmable bulbs.
In this style 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 low-light applications where lights remain on for extended periods.
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.
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.
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.
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 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.
