LED Light Bulbs Reviews | Info You Need To Know

Ahhh, The old standby, the incandescent light bulb. It has served all of us well for many years, but before this was invented, the idea had been around for quite a while. No one could perfect this idea until 1879.

About 1877, Thomas Edison had some ideas on how to make a practical light bulb and got to work on it. After about 1-1/2 years of intense efforts and trails, he had perfected the incandescent light bulb. The bulbs of this type available today still use this same basic technology with minimal improvements.

The light this type of bulb produces is very useful, but now that we have other choices, the down side of this bulb is painfully obvious.

The biggest downside is that approximately 90% of the power consumed by an incandescent light bulb is emitted as heat, rather than as visible light. These bulbs also do not last very long, so the cost of power consumption and bulb replacement is high.

Now, with the evolution in lighting technology, we now have much better choices.

Here is the 2nd generation of household lighting, the CFL screw in bulb.

These bulbs represent a substantial increase in efficiency, as they outlast the incandescent bulbs by about 12x and only use 20 to 33 percent of the power.

As an example, a standard 40 watt replacement would only use about 9-13 watts of power. A pretty good savings!

The biggest downside of these bulbs is the poisonous mercury that is in the tube. When they finally do blow out, the disposing of these bulbs becomes an issue. Mercury can leach out from dumps, poisoning our water supply and damaging the environment. Not Good, so proper disposal is extremely important!

Finnaly, an extremely efficient and enviomentaly friendly light bulb is here! LED technology has been around for quite a while, but was not a realistic alternative for general household lighting, until now!

Over the past several years, the LED lighting technology for practical use in a bulb for the home, has made huge advances. Practical LED bulbs are now available for home use, and boy, are these things efficient!

The up front cost of an LED bulb is higher than the incondescents, but don't be fooled. The cost of these bulbs over thier life time is actually significantly less than all other options.

As an example, the bulb pictured here only uses 7 watts of power to replace a 40 watt incondescent bulb! This bulb will last up to 50,000 hrs! At 8 hrs a day, that's 17 years, and only cost about 2 dollars a year in power costs!

Incandescent lamps are generaly manufactured to have a lifespan of about 750 hours or 1,000 hours.
The LED bulbs will last up to 50,000 hrs!

When you look at the costs to run traditional incandescent bulbs, they simply don't make sense any more.

One - 100 Watt bulb costs about $43 dollars to run per year at 12 hours per day. But don't forget that since an incandescent bulb only lasts 1000 hours, chances are you would have bought at least 4 replacement bulbs over the course of the year, bringing your total cost for just one light fixture to $50.

Now let's compare this to.........

One - 10 Watt LED costs about $4.30 to run per year at 12 hours per day. Since it was on for approximately 4000 hours it still has nearly 10 years of life! Even throughout its entire 11 year life, a 10 watt will cost approximately $120 while a traditional fixture using an incandescent bulb will cost nearly $550!

As you can see, replacing the majority of the lighting in your home with LED bulbs can really add up in terms of real money saved, and you are aslo helping the enviorment with less green house gasses and no polutants when discarded!
