Transition to LED lamps to bring massive savings globally

According to a report from IMS research, the widespread adoption of retrofit LED lamps will create global energy savings worth $100 billion over the next five years. The study entitled Opportunities for power components in LED lighting revealed that although LED lamps are not currently used as a primary option for general lighting, a rapid uptake of retrofit LED lamps will result in a potential market of more than 4 billion units by 2016. While current legislation encourages a switch to LED lighting, there is a forecasted acceleration of this switch as consumers become more aware of the long term savings when compared to other lighting technologies.

LED lighting to drastically reduce power consumption
Ryan Sanderson, co-author of the report commented, "The environmental impact that global adoption of LED lighting will have is colossal. Lighting accounts for approximately 19 percent of the world's energy use at present. IMS Research predicts that in 2016 around 15 percent of all lighting will be accounted for by LED, which would reduce global energy consumption of lighting by around 20 percent."

Compared to incandescent lamps, retrofit LED lamps consume less power while providing same luminescence. The study forecasts that in 2012, the use of retrofit LED lamps in place of incandescent lamps will result in energy savings of more than 90 gigawatt hours. By 2016, these savings are forecasted to reach more than 300 gigawatt hours. In that five year span, power savings are projected to exceed $100 billion dollars.

LED lighting offers better solution to global energy needs
Jonathon Eykyn, co-author of the study added, "To generate the 800 GWe of energy in 2016 years you would need to run more than 50 nuclear power stations at full capacity. At a time when the world is struggling to balance the use of more sustainable power sources with the need to provide access to low cost power sources to support economic growth, LED lighting could be a large part of the solution."

The benefits of using LED lamps to the general consumer are reductions in average household energy bills. The current cost to buy and power an incandescent lamp for four hours a day for a year is at $20 dollars. On the other hand, an LED lamp would perform the same task at the cost of $16 dollars. However, compact fluorescent lamps (CFLs) compete much better on efficiency against LED lamps, and provide a lower-cost alternative to incandescent lighting.

CFLs vs LED savings
While CFLs cost $6 to buy and power for a year, LED lamps use half the power that a CFL lamp consumes while providing better lighting quality. LEDs also have an average life expectancy of 30,000 hours which is 30 times longer than an incandescent lamp and 3.75 times longer than a CFL lamp. If the savings were calculated over the lifetime of the lamp, LED lamps become the cheapest solution. For example, a typical house with 15 lamps would save more than $5,100 over 20 years by switching from incandescent to retrofit LED lamps. A house with CFLs installed would save nearly $500 over 20 years by moving to retrofit LED lamps. These savings will increase as the cost of LED lamps continues to fall significantly, especially over the next five years.
