Light fixtures are referred to by the NEC (National Electrical Code) and any electrical professional who likes to sound smart, as luminaries. There are rules we need to discuss concerning where and what kind, are allowed to be installed in a home. LIGHT FIXTURE RATINGS: Light fixtures are rated for where they may be [...]

LED AND THE ENVIRONMENT
Tests conducted at the University of California-Davis and Irvine, on LED traffic lights, automobile headlights, brake lights and Christmas tree lights, showed unsafe levels of some toxins. After LEDs were crushed, they were found to contain lead, arsenic, nickel and other hazardous substances. Their conclusions may put a damper on the growing popularity of [...]
LED, ORGANIC LIGHT
THE BIRTH OF OLEDs: Organic Light-Emitting Diodes, or OLEDs, were invented by Dr. Ching Tang at Eastman Kodak. Although this took place in the late 1970’s, it is just now (over two decades later) finding its way into markets. It was confined to cell phones and small video displays for years, now it is [...]
LED, PROS AND CONS
ADVANTAGES OF LED LIGHTING Some advantages of LED lighting over conventional lighting sources: Lifetime LED lights can last from 30,000 – 75,000 hours (50,000 hours is the average) depending upon the quality, durability and use of the fixtures. With an average use of 6.5 hours per day, this can amount to over 21 years of [...]
LED, WHAT IS IT?
Light Emitting Diode (LED) is a semiconductor light-producing unit. When an electrical current passes through the unique materials, there is a recombination of positive and negative charges resulting in the emission of photons, as light energy. This action is called electroluminescence. The color of the light is determined by the energy gap of semiconductor and [...]
