1 What is a  LED Lighting?

 LED lighting has been around for many years and is just now really coming into its own. For years, the Light Emitting Diode was simply used as an indicator or display light in various small-scale applications. Think of those old Texas Instruments calculators, or your blinking VCR light.

 LED is a solid-state technology. This means there is no glass bulb, no pressurized gases, no mercury and no burning filament. In the traditional bulb, Heat was the main result while light stood as a mere by-product of electrifying the filament.

With  LED technology, what you have is a circuit board and a computer chip. The properties of the chip create light that is generated and focused through a plastic diode to create light. Depending on the chip and materials used, different colors in the color spectrum can be created. Early on the easiest color to create was red, which is why your calculator and VCR had red display lights rather than any other color. For many years, there were no advancements in  LED technology and very little change in lighting technology over all; changes that did occur were mostly just plays on a theme. Metal halide, fluorescent, etc. were all just different ways to do the same thing with different effects.

In recent years,  LED technology has completely changed and reinvented the light bulb and the way we think about lighting in general. This was not really possible prior to the technological revolution of the ¡®90s and the rapid advancement of the microchip. The same advancements that spurred the computer to reach dizzying levels of efficiency have also done the same for the  LED. Just as computers have become faster and cheaper,  LEDlights have become brighter, smaller, less expensive, and more sophisticated.

2 Benefits of LED Bulbs

- Save money and energy by using LED bulbs. Generally, an LED consumes less than 0.1 watt to operate. This incredibly low consumption means you will save on your energy costs right from the start.

- The typical LED bulb will last for 50,000 hours. This is over 10 Years of light from One Bulb used half the time. Compared to an incandescent bulb, which lasts 1,000 hours, a halogen bulb lasts 2,000 hours, and a compact fluorescent bulb may last up to 10,000 hours.

- The extremely long life of an LED bulb will virtually eliminate your maintenance costs. There will be no need to change light bulbs throughout the year.

- The solid state technology of an LED is very durable and can withstand high levels of shock and vibration. Its able to operate in extreme temperatures cold, or hot. (-35?C to 80?C).

- LED convert almost all the energy used into the light output, making them a highly efficient light source. LED generate less than 30% of the heat of traditional lighting technologies. With minimal heat generated, LED are safe to the touch and do not produce any harmful UV rays

- LED are environmentally friendly, they are made from non-toxic materials unlike fluorescent which contain Mercury. For more on what LED are made from.

3 What are the advantages of using LEDs over traditional incandescent lighting?

There are quite a few advantages to using LEDs. Generally they are heatless, use 90% less energy, and last ten years. They are also smaller and do not contain any dangerous chemicals like mercury. They can readily be put in places that have always been too small or out-of-the-way for many incandescent lights, as well as in places that were always very dangerous or difficult to get at. Also, the more sophisticated LED apparatuses like wall washers and spotlights are DMX-controllable, which means they can be used in some really impressive ways.

The bottom line is that LED's are easier and safer to use than all previous lighting technologies. Plus, LEDs will save you money by consuming less power, lasting much longer, and generating much less heat, which in turn combine to result in lower climate control costs.

4 What types of LED Lighting products are readily available?

Today there are hundreds of different products available in varying brightness levels, color temperatures, and sophistication levels to meet every lighting need ¨C from those of an architect's latest high-rise condo project, to those of a rural homeowner's kitchen renovation. There are replacement bulbs for screw-in Edison-style bulbs and for nearly every style of Fluorescent. Plus, the LED replacements are of the ¡°plug and play¡± ilk with no other modifications needed. There are also many different types of architectural lighting, such as wall washers and

spotlights.

Finally, our most popular piece of LED lighting is the light bar, which can be used anywhere. From display cases to under-cabinet lighting, our light bars offer a novel (and cost-effective!) approach to accent lighting.

The most exciting product that we are currently working with is a 9 watt recessed light that many contractors are replacing all their incandescent can lights with.

5 How do I compare my current lighting with LED lighting so I can make intelligent decisions?

In the past, we have generally referred to the brightness of a bulb in terms of its wattage, or the amount of power that the bulb uses (or energy it consumes). Because of the disparity between incandescent and LED technologies, we have to change our language a bit in order to account for progress. When referring to brightness, we now find ourselves comparing lumens (see Q: What is a lumen?). However, when comparing LEDs with incandescents, there is no easy mode of comparison because the typical incandescent is projecting light in 360 degrees ¨C everywhere, not just where you need it. Because LED lights are directional, they focus all the light they generate exactly where you want it, and nowhere that you don't.

Another consideration is color temperature. In the past, this has been very difficult to control because you basically got whatever color your particular bulb produced. Typically this was a Warm White (about 3000K) if you had an incandescent bulb, and a Cool White (around 5000K) if you had a fluorescent bulb. Because the LED is an intelligent, solid-state technology, we are able to produce LEDs that not only produce Warm White and Cool White, but are able to produce up to 16 million different colors, each a different temperature .
