Energy Efficiency through LED Technology
Why LED

Which lighting source is the best?  LED Lighting = Less Heat & More Light

   



Standard Light Bulbs, also known as incandescent, create light by passing electricity through a metal filament, when the filament becomes hot enough it glows.

      Incandescent bulbs give off about 90% of the energy they consume in the form of heat, leaving only 10% used to produce light. This equates to about 85 BTUs/hour. 

      The average lifespan of an incandescent bulb is between 750 to 2500 hours.

            





CFL Light Bulbs, also known as Compact Fluorescent Lighting, creates light by passing electricity through a tube containing gases. This reaction produces ultraviolet light that is transformed into visible light by the phosphor coating inside the tune. 

      CFLs use approximately 50 to 80% less energy than incandescent bulbs and last 10 times as long. They also run 75% cooler.

      CFL bulbs contain mercury, which is considered a toxic metal. While present in small amounts, burned out or broken bulbs must be treated as hazardous  waste material when disposed of.




LED Lighting
stands for Light Emitting Diodes. LEDs are small light sources that become illuminated by the movement of electrons through a semiconductor material.

      LEDs are cool to the touch and 90% of the energy they consume is given off in the form of light, with less than 10% given off as heat. They use up to 90% less energy than incandescent bulbs.

      LEDs are rated to last between 35,000-50,000 hours, which is at least 20 times that of an incandescent bulb. LEDs, however, don't "burn out" as an incandescent or CFL bulb would. The lifetime of an SSL lamp is generally considered to be the point where the light output has declined to 70% of its initial output, measured in lumens. So instead of burning out after 35,000 hours, the bulb will only be slightly dimmer.

     



3W High Power LED Bulb - Comparable amount of light as a 25W incandescent flood.


10W High Power LED Bulb - Comparable amount of light to a 50W incandescent flood.


18W High Power LED Bulb - Comparable amount of light to a 100W incandescent flood.
