What is the Difference between LED Light Bulbs and CFL Bulbs?

If you are looking to go green, then your top two light bulb choices are Led light bulbs and CFL bulbs. While both of these options will emit light and are more energy efficient than halogens, they are different in just about every other aspect.  LED light bulbs, or light emitting diodes, are eco-friendly all around. They do not contain any dangerous substances or chemicals.  CFL bulbs, or compact fluorescent lights, contain mercury gases.  If a CFL bulb breaks apart, then this gas gets emitted into the air.
In the past, CFL bulbs were much more readily available.  However, they were not the most popular choice except for commercial properties.  The disadvantages of CFL bulbs are that they are not very attractive, take a while before they warm up to their full lighting, and will lose some of their lifespan every time you turn it on or off. CFL bulbs also are notorious for making a humming noise and flickering – another reason why they have largely stayed out of homes.  LED light bulbs do cost more but they have become very popular amongst homeowners and businesses alike.  LED light bulbs are the more eco-friendly choice, last much longer then CFLs, do not lose their lifespan when turned on/off, have a beautiful light quality, do not create heat, and aren’t going to flicker or hum.

Why LED’s?

  • Produce low heat (up to 35deg)
  • Durable (housing made from high quality aluminum and lenses for polycarbonate and shatterproof glass)
  • Long lifespan. Lasts up to 10x longer than CFL’s and 50x longer than incandescent
  • No Toxic gasses or material used (e.g. Mercury)
  • Quality of light—No strobing, infra red or Ultraviolet light 
  • Up to 80% cost reduction on electricity bill for lights and supply demand

Why are LED’s so expensive?

  • Components on the circuit board is often assembled by hand because its still too complicated for factory machines.
  • The actual LED wafer can cost as much as $8 a unit.
  • The brightest LEDs generate blue light. So in order to get the more natural white glow, manufacturers typically  coat the bulb with yellow phosphor, an expensive rare earth metal compound.
  • LEDs additionally require the use of drivers to convert energy into electrical current. This component alone can cost up to $4.
  • Although LEDs burn cooler than Edison bulbs, they still need a conducting material to dissipate the heat. The aluminium used to accomplish this can cost as much as $3.
