A $5 LED bulb

Lemnis Lighting has introduced three varieties of LED bulbs, including one priced at $4.95.  LED bulb prices have been in a virtual free fall. 

In fact, the Department of Energy has predicted the price of LED bulbs will drop around 30% a year from 2010 to 2015 and 10 to 15% a year from then to 2020.  For an example of what that could mean: if you started with LED bulbs priced at $20 in 2010 and applied those price reductions over that period of time, you’d end up with LED bulbs priced below $2 in 2020.  

Even at current prices LED bulbs are a good investment.  It would cost about $5.69 a year to use an incandescent bulb for three hours per day at a rate of $0.13 / kWh, but only $0.85 a year to use a LED bulb the same amount and at the same rate.  A LED bulb can last up to 35,000 hours vs. up to 1,000 hours for a typical incandescent (Think of the extra costs to buy 35 incandescent bulbs during the life of one LED bulb).

LED bulbs will be a new technology leap-frogging another – CFL bulbs.  Considering LED bulbs:

  • Are even more energy-efficient than CFL bulbs
  • Can last much longer than CFL bulbs 
  • Contain no mercury
  • Are available in a much greater variety of light colors than either CFL of incandescent bulbs – including some that have a light color indistinguishable from light given off by incandescent bulbs
  • Will end up cheaper than CFL bulbs because of the relatively labor intensive methods of producing CFL bulbs

it’s only a matter of time before LED bulbs dominate the light bulb market.
