Why LED? A Guide to The Next Generation of Lighting
LED Basics and Background A light-emitting diode (LED) is a semiconductor chip that emits light when conducting current. LED's are very versatile due to their ability to emit nearly all spectrums of light. This has led to their nearly universal adoption as a light source for a wide range of applications from: status indicator lights, to traffic signals, to today's advanced direct replacement LED light sources.
Although, LED's that produce a practical spectrum of visible light have been under constant development since the 1960's, only recently have LED's that can produce acceptable levels of illumination - for a primary lighting source in a home or business - seen mass production. The pace of innovation in the field of LED illumination, also referred to as Solid State Lighting (SSL), is currently progressing at an amazing pace.
Benefits of LED Long Life Many LEDs are rated to have a 50,000+ hour lifespan, in this same amount of time you will buy over 50 regular incandescent bulbs or 5 compact florescent bulbs!
When you look at the costs to run traditional incandescent bulbs they simply don't make sense: One - 100 Watt bulb costs approximately $43 dollars to run per year at 12 hours per day. But don't forget that since an incandescent bulb only lasts 1000 hours, chances are you would have bought at least 4 replacement bulbs over the course of the year, bringing your total cost for just one light fixture to $50. Compare this to... One - 10 Watt LED Bulb costs approximately $4.30 to run per year at 12 hours per day. Since it was on for approximately 4000 hours it still has nearly 10 years of life! Even throughout its entire 11 year life an LED will cost approximately $120 while a traditional fixture using an incandescent bulb will cost nearly $550!
Environmentally Friendly by Design
EarthLEDs are the most environmentally friendly light source other than pure sunlight. First, there are no hazardous substances used inside EarthLEDs. All of our products are RoHS compliant (a strict new standard reducing hazardous substances). You've probably heard a lot about Compact Florescent Bulbs or CFL. These have been touted as a solution to the inefficiencies of incandescent yet they are all made with mercury, thus they are hardly an environmentally sound solution after all. Second, EarthLEDs are part of the solution to the energy crisis we are all facing. EarthLEDs use less power up front and generate less heat when used. Replacing all of your lighting with EarthLEDs will suddenly make your home or building an environmentally friendly structure. Finally, with the long life you will achieve from your EarthLED bulb, you will save on the disposal of approximately 50 incandescent bulbs and 5 mercury tainted, compact fluorescent bulbs thus cleaning up our landfills and ultimately saving our environment from waste.
EarthLEDs are available in white and warm light color temperatures for the utmost in flexibility. No matter which temperature you choose, you will always get pure, clear light that makes reading or viewing objects easier on the eyes. Tired of annoying flickering and headaches caused by compact fluorescent bulbs? Say hello to EarthLEDs and their consistent visibility.
