LED Lighting 101
What is an LED?
A Light-Emitting Diode (LED) is a light source created from a small chip and in a semiconductor. Invented in the early 1960’s LEDs have generally been more expensive and could only be used for specific applications. Even just a few years ago LEDs could not replace most conventional indoor lighting properly and would only be seen in; accent lighting, traffic signs, parking lots, and other outdoor lighting fixtures. Entering into 2012 LEDs have advanced far beyond the lighting capability of normal incandescent or Fluorescent bulbs. With the government phase out of the regular “Thomas Edison” bulbs and the harmful affects of Compact Fluorescent Light’s (CFLs) LED has become a safer, more efficient, and brighter way to go.
Benefits of LEDs compared with incandescent and fluorescent
LED light bulbs are extremely energy efficient using 90% less energy than other bulbs in the market place today. Whether it’s from Nuclear or Solar Power everyone benefits from using less energy. Without a filament to burn out and waste energy LEDs can last over 100,000 hours or 15 years without needing to be replaced. You can realize a 100% ROI in two years due to lowered energy costs. LED lights are unaffected by repeated cycling (on and off) of switch. LEDs do not use ballasts that burn out; additionally, LED lights require less energy to manufacture over traditional lighting products.
HEALTH AND SAFETY
LED lighting contains NO mercury which has been linked to insomnia, headaches, mood changes, muscle atrophy, tumors, autism, mental retardation, dyslexia, and other adverse side effects when inhaled, ingested, or absorbed through the skin.
According to the EPA recycling CFLs is important because it prevents the release of mercury into the environment as they often break when thrown into a dumpster, trash can or compactor, or when they end up in a landfill or incinerator.

Flickering in older Fluorescent tubes can contribute to the start of a headache, or even seizures in some people.
Fluorescent light allergies – when a Fluorescent light aggravates a preexisting condition and can cause health issues from headaches to skin rashes. There is an estimated 40 lbs of mercury per day being dumped in each of our nations major cities from just consumer purchased CFLs.
