ENERGY EFFICIENCY

Environmental and Energy Savings

EII LEDs require 20% of the power to produce the same lighting as conventional compact fluorescents (CFs) for the same Lumen value. Compact fluorescents produce approximately 11.25 lumens/watt. EII LEDs produce 108 lumens/watt and because of the safe nature of the lighting and the almost limitless installation options, can be positioned exactly where the lighting is needed most. LED lighting can also be recycled and compared to mercury and phosphor emitting CFs are much more environmentally sustainable.

Product Lifetime Measured in Decades

Compared to compact fluorescents (CFs) which has the closest energy efficiency rating next to LEDs, the difference in product life expectancy is remarkable. With a 60,000 hr. rating for our LEDs vs. a typically CF rating of 6,000 to 15,000 hrs., the LED’s have a 4 to 10 time greater life expectancy. If you considered 8 hours of use of your LED system per day, it would take 20.5 years to reach the rated lifetime of LEDs vs. 2 to 8.2 years for CFs.

Also keep in mind that most CFs are rated for continual operation and do not take into account the way people actually use lighting. The life of a CF is significantly shorter if it is turned on and off frequently. In the case of a 5-minute on/off cycle the lifespan of a CF can be reduced to "close to that of incandescent light bulbs," which they were designed to replace, according to the U.S. Energy Star rating system. Incandescent bulbs are generally rated at 750 to 1,000 hrs. LEDs, by comparison, do not wear down based on turning the unit on and off.

Environmental

If a compact fluorescent breaks, people are advised to immediately leave the area because of toxic levels of phosphor and mercury. If an LED is damaged, there is no release of toxins or dangerous materials and they can be easily replaced. As well, LED lighting can be recycled. Besides the environmental damage of mercury-emitting CFs, changing conventional bulbs also requires much more energy than EII’s low-maintenance LEDs. The lifetime of LEDs exceeds conventional bulbs many times over, meaning that the energy required for maintenance and replacement is greatly reduced, again providing numerous environmental, management and maintenance benefits.
