A light bulb is a light bulb – right? Not in today’s lighting market.  There are enough light bulb styles to make a light bulb consumer dizzy. The chart below helps sort out the differences between the three main types of light bulbs, LED, Comapct Fluorescent (CFL) and incandescent.

Here’s Some of the Ways in Which LED, CFL, and Incandescent Light Bulbs Vary
  LED CFL Incandescent
Cost Expensive Moderate Cheap
Replacement / 50,000 Hrs 1 5 42
Avg. Life 50,000 HRS 8,000 HRS 1,200 HRS
Light Output per 800 Lumens 6 to 8 Watts 13 to 15 Watts 60 Watts
Start Up Instant On Slight Delay Instant On
Dimmable Yes If Designated Dimmable Yes if Designated Dimmable Yes
Durability Tough Fragile Fragile
On-off Cycling No Effect Shortens Life Minimal Effect
Heat Given Off Low 3 BTU/HR Medium            30 BTU/HR High 85 BTU/HR
Sensitive to Cold No Yes Some
Mercury Enclosed No Yes (Minimal) No

A Dependable Line of LED Lamps

LED BR30 FloodlightConsidering the bits of information above, one of the best lines of LED light bulbs I’ve found is the TCP Dimmable Floodlight series. They offer smooth, uniform dimming from 100% to 0.5% with consistent color. The lamps exceed all industry standards. Highly efficient LEDs and driver allow for long life, exceeding 25000 hours. UL listed for damp locations. Ideal for use in recessed cans, track lights, display lights and outdoor fixtures (protected from the elements).

I have these in my family room.  They give off good dim well.   Visitors don’t even notice they are LED flood lights. You may read about them here.

Awesome Dimming CFL Light Bulbs

TCP TruDim CFL Light Bulb I also use the TCP line of Pro Series TruDim dimmable CFL light bulbs in my kitchen.  With uniform dimming from 100% down to 2% and digital technology for faster run-up time, they beat other CFL dimmables.  Most start flickering when dimmed down past 20%. Take a look here.  They are available in spiral, R20, R30, R40 floodlights, A-lamp and G25 or G40 globe shapes.

As for Incandescents….

There are two incandescent light bulbs left in my house.  One in the almost-inaccessible attic which was put there when we moved in 23 years ago.  I think it’s been turned on once or twice. The other is in our ancient garage door opener.  I’ve found LED light bulbs and CFL lamps do not work there, probably because of radio frequencey interference. Maybe your opener is different.

I’ve found CFL light bulbs to be very accomodating in my home.  And with the exception of an occasional dud, long lasting – to the point I wish they would fail so I can replace them with the newer versions of LED light bulbs.
