WSRM---LED BULBs lights is the new home appliance!


WSRM---LED BULBs lights is the new home appliance!
Introduction
With incandescent light bulbs being phased out due to the The Energy Independence and Security Act of 2007, consumers have been subject to nothing short of one-sided and misleading hype about CFL lighting as being the safe “green” energy efficient lighting solution of the future. Educated consumers however, have discovered just the opposite. Either through direct experience or their own research on the subject, they are discovering that CFL lighting hazards, poor reliability and the environmental risks are not acceptable, and are looking for other lighting alternatives. One such alternative is LED lighting and it fortunately has come of age.
 LED light bulbs are the most energy efficient, reliable and long lasting lighting source currently available. Current LED bulbs last up to 50,000 hours and unlike CFL's their lives are not shortened by being turned on and off frequently as we normally do with a light bulb. LED’s are significantly more energy efficient than compact fluorescent lighting (CFL) and contain none of the toxic mercury vapor hazards of CFL's. No need to follow 12-step EPA hazardous material guidelines as when a CFL breaks, for example in your child’s bedroom.
LED Lighting: The New Home Appliance 50,000 hours. Think about that. At 50,000 hours of life and an average of say 3 hours of use per day, the LED is a lighting source with over 45 years of useful life! That’s why I call LED lighting the new home appliance. These light bulbs are no longer disposable commodities but a long lasting piece of lighting equipment in your home that will last for generations.

So what exactly is LED lighting? It’s an electronic solid state light source introduced in the 1960’s that uses Light Emitting Diodes to create light. The LED has seen significant improvements in electronics, optics and materials, all of which have contributed to the successful development of this lighting technology. Especially noticeable is the recent improvement in color rendition of the light provided by LED’s. Gone are the days of unacceptable bluish white colored light. Today’s LED’s have the natural warm white color of the incandescent bulb.
Let’s take a look at this great lighting technology.

LED lighting is the most energy efficient lighting available today and is about 80% more energy efficient than CFL's. LED's also provides the longest bulb life at up to 50,000 hours. Let's take a look at how LED lighting compares to CFL, Halogen and Incandescent technologies.
    Energy Efficiencies of Various Lighting Types
    The following list shows the annual energy consumption of light bulbs (operating 8 hours per day) with light levels equivalent to a 60 watt incandescent bulb. The the low annual kWh energy consumption of LED lighting is clear.
  • 60 Watt Incandescent Bulb (630 lumens): 175 kWh/year
  • 43 Watt Halogen-Incandescent Hybrid Bulb (750 lumens): 126 kWh/year
  • 15 Watt CFL Bulb (900 lumens): 44 kWh/year
  • 8.3 Watt LED Bulb (800 lumens): 24 kWh/year



Features and Total Cost of Operation for Various Lighting Types
Next, let's expand the above list and summarize some the main characteristics of each lighting type, including wattage, life (hours), bulb cost and energy cost. Since an LED bulb sets the standard at 50,000 hours of life, let's use that as the timespan for the cost comparison.
    LED Lighting
  • 800 lumens (LED equivalent to 60 watt incandescent)
  • Dimmable
  • Color Temperature: Warm white (3000 Kelvin)
  • Energy used: Actual 8.3 watts (11 watt nominal)
  • Bulb Life: 50,000 hours (approx 45.7 years at 3 hours/day)
  • Warranty: 36 months

Bulb Shape:The standard incandescent light bulb is an A-Series general purpose lamp called a Type A19 bulb. They have a screw-in Edison base (similar to screw-in-type fuses). The number 19 refers to the bulb's width in increments of 1/8 of an inch. So "19" means 19 1/8"s or a diameter of 2-3/8". The incandescent bulb has its filament in the center of the rounded bulb and radiates light with a fairly even light distribution pattern including illumination near the bottom of the bulb.LED Lighting – The New Home Appliance
LED Bulb Shape:
Although LED lamps retain the basic shape of the incandescent A19 bulb, they distribute light differently. The LED has its electronics and light emitting diodes mounted in the bottom of the bulb. As a result, LED bulbs naturally distribute light in a directional manner out the top and side of the lens. In the photo above you see heat sink fins at the bottom of the bulb and two different lens designs. One is a directional lens design and the other is an omni-directional design.
With the directional LED lens light from tends to be distributed more heavily to the top and sides of the bulb.
The omni-directional LED lens is a somewhat bulbous lens diffuser design that extends beyond the diameter of the base and allows light to radiate in all directions, similar to an incandescent bulb.The improved quality of LED light color is what has ultimately sold me on this lighting technology. They have now improved LED lamps to the point where color rendition is virtually that of an incandescent bulb and looks very normal. Gone are the days of "bluish-white" light color.

If you wanted more downward light throw instead of the primarily upward throw of the directional LED lamp shown, just use an omni-directional LED bulb. The color of the LED lamp in the fixture however, is great and looks very natural.
