LED Light Bulbs Discount Lightbulb Advice

LED light bulbs are now available as a replacement to traditional incandescent lightbulbs. As is often the case with upcoming technology, LED replacement bulbs are priced differently by each retailer. If you’re concerned with buying these bulbs at the best price, we suggest shopping around a bit before making a purchase. In recent months, we’ve found discount LED lightbulbs available at overstock.com and the Home Depot website. Additionally, eBay.com is a great place to purchase discount LED light bulbs, especially when doing so in bulk.

About LED Lighting

LED lights are perhaps the best alternative to the old inefficient incandescent lightbulb. The greatest benefit is the life span. The lamp will last for ten years or more, which is 30 times the lifespan of an ordinary incandescent. In fact, greater lifespan than this is possible. LSI Industries of Cincinnati Ohio boasts of lamps with a lifespan of over 100,000 hours when the ambient temperature is below 40 Degrees C. Another advantage is the hardiness of the lamp. There is no filament that burns out on electrical surges or breaks during rough handling. There is no warm up period. The lamp lights instantly to full brightness. And there is no wasted heat, as in incandescents where most of the power consumed is not as light, as it should be, but as heat. The LED lamps save a tremendous amount of energy. They are eight times, 800%, more efficient than the regular lightbulb. This will certainly show up on the monthly electrical bill.

LEDs Some History

LEDs have been around for a long time, but recently the technology has improved, and with the need for energy efficiency, further developments are evolving at rapid speed. The diode is a semiconductor which was first made as a one way electronic switch. Current would pass in one direction easily, but the diode would oppose, or resist, current flow in the other direction. The LED is a light emitting diode first announced in 1927 by a Russian scientist, as he observed that photons were produced when passing current through a diode. It wasn’t, however, until 1961 that experimenters at General Electric applied for and received a patent. Further developments continued until the Monsanto Company finally mass produced the red LED in 1968. These were used in seven-segment displays of alphanumeric characters in many appliances, such as TVs, radios, telephones, calculators, etc. The light output was low then, but served its purpose. As the technology improved greatly, other colors became standard, and then in February 2008, Bilkent University in Turkey reported 300 lumens of visible light by using nanocrystals.

Today’s LED lamps

Today’s LED lamps are made up of multiple LEDs with proper technology to produce bright white light or any other desired color. Various materials, coatings and reflective methods are used to provide a highly satisfying light in many industries. They are installed in cars, trucks, RVs, flashlights, traffic lights, home and commercial lighting, Christmas lighting, airplanes – actually, you name it – they are even used in satellites and spacecraft. LED replacement lightbulbs are the light of not only the near future, but of today.
