Best place to start: Philips LED bulbs at Home Depot.
LED bulbs are now practical and affordable alternatives to both Incandescent and Fluorescent (CFL) bulb that fits in a standard socket (E26 base), offering lower power consumption, less heat and much longer life. There is also a growing selection of replacements for different socket sizes and fluorescent tubes typically used in office buildings. In fact, LED flashlights were available years before standard light bulbs.
Learning a lesson from the stories of early CFL light bulbs overheating, exploding, shattering, mercury hazards requiring Hazardous Materials cleanup, flickering and causing radio interference, current best advice is the same for LED bulbs: stick with established makers of incandescent light bulbs.
Initially, standard size LED bulbs cost significantly more than both Incandescent and CFL bulbs. As you can see below, that is starting to change. Prices for the venerable 60 watt Incandescent light bulb, and its CFL and LED equivalents are shown with the lowest prices (December 2016), per bulb, when bought in multi-bulb packs:
- $2.49 LED – 4 for $9.97
- $3.08 CFL – 6 for $18.47
- $0.45 Incandescent (not generally available)
Comparing the power usage:
- 8 watt LED
- 13 watt CFL
- 60 watt Incandescent
That is seven and a half times as much power for the Incandescent as the LED.
White LED bulbs vary in the following ways:
- Colour of light, typically Daylight or Warm White
- Intensity of light, typically indicated as equivalent to 40, 60, 75 or 100 watt incandescent bulbs, though LED is generally brighter because they use less coating than the typical “Shadow Ban” incandescent bulbs
- Shape of bulb
