The World Falls In Love With LED
LED lighting has taken the world by storm. Believe it or not the incredible LED light bulb was invented 1/2 century ago by Nick Holonyak Jr, now known as the Father of the LED. Mr. Holonyak is an American scientist that was working on laser technology in a GE laboratory. His discovery was a visible laser in the red spectrum could be made from Silicone Carbide and can be controlled and modified. Now over 80, and holding a new 27 watt GE Edison 100w equivalent the inventor commented, "its only the beginning". For decades this incredible Light Emitting Diode (LED) was used mostly in specialty applications such as NASA control panels, scientific applications, indicator lights and eventually traffic signals. In fact wide scale LED production, innovation and public adaption did not begin until the concern began to develop over energy pollution and its relation to climate change. It was not long after, that building efficiency became an important solution to pollution reduction. According to a Energy Information Administration (EIA) report there is over 10 billion lit commercial floor space and growing quickly. The EIA study shows that 38% of total energy used by these buildings, over 1,143 trillion BTU, is lighting. Fortunately with modern advancements in; Compact Florescent Lighting (CFL), lighting controls and LED technologies, savings of up to 80% can be obtained cost effectively.
Business have had some difficult decisions over the past 5 years, the superior LED products are dropping in price and government incentives do not last forever. So early adaptors to LED have had to accept higher ROI's but are reaping the some of the tangible and intangible benefits of the superior product listed below:
Extremely long lamp life 35,000 to advanced 100,000 hours / Use about 20% of the energy of a incandescent bulb and 80% of a comparable CFL / Easily retrofit / Completely programmable and dimable / Wide variety of light colors and moods / No Mercury / Immediate Start up / Not cold sensitive / Produce little heat or UV light / Make products look better, attract customers / Increased employee productivity mood and comfort. ............... Solid state lighting technology includes several promising technologies; Efficient LED, Organic LED, Polymer LED and Light Emitting Plasma (LEP). Developers believe that this technology still has further efficiency per watt potential and wide scale production is furthering advancements and reducing prices. These improvements in combination will contribute to the potential of faster ROI's on lighting projects. Just be careful of waiting for these advancements and missing out on incentives available from State, Federal and power provider sources. The intangible benefits of solid state lighting should not be overlooked as they might be more valuable than the energy savings alone. First of all, the heat reduction from a lighting conversion is often more significant than people realize. Incandescent bulbs, ballasts and CFL's all create more heat than LED and this will contribute to the rising cost of "peak demand" priced air conditioning. More important is the research in lighting and its effects on employee productivity. A Study by Leviton finds that 57% of employees report stress relating to their ability to see. Research has confirmed that proper lighting affects the human circadian system and can decrease depression. According to the Lighting Controls Association (LCA) studies show that workers are more satisfied and productive with personal control over their thermal comfort and lighting. Evidence shows that age, task, and individual preference call for a wide range of lumens. Efficient LED lighting pairs perfectly with personal lighting controls, creating a synergy resulting in dramatic reductions. With the cost of salaried production being the highest reported cost to American business, the positive effects of lighting on employees alone may be worth the upgrade to LED.
