What is a LED?

A light-emitting diode, or LED, is a solid-state semiconductor that emits light when a current passes through it. LED light bulbs can replace an old incandescent or CFL in all your existing fixtures, including track lighting, room lighting and outdoor flood lights, just to name a few.

While the Government slowly phases out inefficient incandescent bulbs, many consumers are seeing the value in LEDs. Not only will they save you money on your energy bill, they will last 25x longer than your old bulbs! No more worrying about changing those hard to reach lights!

LED Bulbs

  • Have a long lifespan! They can last up to three times longer than CFLs and 20 times longer than traditional incandescents.
  • A typical LED light that burns three hours a day can last about 22 years before it needs changing, making LED bulbs an ideal choice for hard-to-reach lights.
  • Have no filament or moving parts, making them durable and low-maintenance.
  • Generate almost no heat or UV rays, which can help reduce air conditioning costs in your home
  • and help keep fabrics and furnishings from fading.
  • Save energy as they are up to 85 percent more energy efficient than incandescent bulbs and 10 percent more efficient than CFL bulbs.

While LED household lighting may require a higher initial investment, their longevity, low maintenance and significant cost savings make LED bulbs a purchase that can pay for itself over time.

LED Light Bulbs Made Easy

1. Select Shape

• Spotlights for track lighting
• Floods for outdoor and recessed lights
• LED candles for wall sconces and decorative fixtures
• A-line bulbs for room lighting and lamps

2. Choose Brightness and Energy Efficiency


  • Look for bulbs with high lumens and low wattage for the best energy cost savings
  • Divide the lumens by the wattage to determine the best brightness-to-energy usage ratio
    • Replacing a 40-watt bulb: look for at least 450 lumens
    • Replacing a 60-watt bulb: look for at least 800 lumens
    • Replacing a 75-watt bulb: look for at least 1,100 lumens
    • Replacing a 100-watt bulb: look for at least 1,600 lumens

3. Choose Color Temperature (Measured in Kelvins)


  • Soft light for indoor applications and small areas
  • Bright light for outdoor lighting and indoor task lighting
  • Lower Kelvins equals warmer, yellow light. Higher Kelvins equals colder, bluish light.
4. Match Fixture Base

  • Screw-in bases include miniature candelabra, candelabra, intermediate and medium
  • Pin bases typically have two pins, such as those used for many halogen lights

Features to Consider

Dimmability: Not all LED bulbs are dimmable, but most are. You should check the specifications of the bulb if this is a feature you want.

Home Automation: WiFi technology is available for turning LED light bulbs on and off, dimming, setting scenes, and even changing the color of the light.

Remote Controls: LED bulbs with remote controls provide convenience and eliminate the need for dimmers.

Warranty: Many LED bulbs come with a warranty covering replacement costs if the bulb malfunctions.

Which Bulb is right for you?



A Shaped Light Bulbs

"A" type bulb shapes are standard house hold light bulbs. The number after the bulb shape is the number of eighths of and inch in diameter. For non-imperial measured bulbs the number following the bulb shape is the number of centimeters at the widest point of the bulb. Standard bulb sizes include A19 for imperial measurements and A60 for a slightly smaller metric measured bulb.

B and C Shaped Light Bulbs

B shaped bulbs are also know as Candelabra Light Bulbs. The have a bulged base that tapers to a rounded or pointed tip. In some bulbs the tip is bent giving the slight look of a licking flame. C shaped bulbs are similar to holiday lamps.
These bulbs are common in chandeliers, night lights and lower wattage applications such as holiday string lights.
Typical bases for B and C shaped bulbs are E12 in North America.

PAR Light Bulbs: PAR16, PAR20, PAR30 and PAR38

PAR light bulbs utilize a parabolic mirror or reflective surface to focus the light. For LEDs the PAR designation is used to define the shape, as most do not have a reflective lower surface due to the directive nature of LEDs.
Common PAR lamps include the PAR20, PAR30, PAR38 and PAR42, though many other sizes exist. These bulbs come in various beam angles that result in spot and flood lamps.
This shape is very similar to the R shape and in some cases the PAR and R are interchangeable as shapes for LED replacements.
