LED - CFL - Incandescent

This blog will provide individuals, as well as small and large businesses, with the information needed in making economically smart choices in lighting products.  
The results will save them money while decreasing the overall demand for energy.

Light Changes
Energy Saved
Demand Reduced

We all have a part to play in reducing our dependency on energy.  With the rising cost of energy we need to take advantage of all logical ways to reduce and control costs.

We will focus on the differences between the LED & CFL Light Technologies since the standard used today is still the Incandescent Light Bulb.

Did you know that only 2% of total energy consumed by LED-based lamps is used in their production? 


When trying to determine the most cost effective and least demanding use of energy among lighting products, we should consider the life cycle of each product.
  • Manufacturing
  • Use
  • Disposal

The U.S. Department of Energy has released a few life-cycle assessments (LCA) of LED lights.

Carnegie Mellon study:




Light Changes
Energy Saved
Demand Reduced

Interesting conclusions can be seen in a LCA study released by LED maker Osram which was conducted by the Siemens Corporate Technology Centre for Eco Innovations.


Did you know that it takes...
  • 25 Incandescent Light Bulbs at 1,000 hours of life
  • 2.5 CFL Bulbs at 10,000 hours of life
  • 1 LED Bulb at 25,000 hours of life
...to reach a life-cycle of 25,000 hours?


LCA Studies LED Lights

We see from both studies (Carnegie Mellon and Osram) that the production of CFL and LED light technologies is a relatively small portion of the total life-cycle.

From the Osram study both LED and CFL consume over 98% of the energy to generate light. Less than 2% percent is allocated to production.

If there where concerns regarding the amount of energy required to manufacture LED lighting they should be put to rest.

LED lighting is comparable to CFL lighting products in terms of energy efficiency at 30 lumens/watt and is continuing to be improved as technology advances. The Carnegie Mellon study predicts that efficiencies of 150 lumens/watt are possible for LED lighting products.






LED technology and products are continuing to be improved and will continue to improve beyond that of CFL products helping to drive down the cost and with one additional advantage. Even if 150 lumens/watt isn't attainable in the near future, a doubling to 60 lumens/watt would leave CFLs falling behind in energy usage and cost.

If you are still not completely conviced  I will provide you one  additional advantage of LED products vs. CFL's:

CFL lighting products contain mercury which is a hazardous material and mercury is considered an environmental safety hazard and require stringent control and caution regarding it's disposal.

Whether you are green motivated or just want peace of mind with regards to the environment and the safety of your family, and there families to come, then any product that can easily be broken, accessible to children and people that know nothing about  mercury and its hazards should not be the product of choice when it comes to deciding on which lighting products you choose to purchase for your business or family.

Light Changes
Energy Saved
Demand Reduced




When we take in consideration the life-cycle of LED technology from manufacturing to use to disposal and compare them to the CFL technology they are comparably as efficient and if we also consider the advancements being made with LED's and the emphasis being put on environmentally save products LED technology is in the long run the most cost effective, economically smart, environmentally safe product to purchase to help decrease your energy consumption within your business or home which will add to your bottom line or pocketbook.
