The Different Benefits Of LED Light Bulbs

As the compact florescent light bulb has started to quickly replace the aging incandescent light bulb lately, another type of bulb is emerging which will replace them both. The light emitting diode (LED) bulb has advantages that make it a superior technology.

Whereas the incandescent bulb creates light within a vacuum and the compact florescent bulb does so in a tube, the LED is referred to as solid-state lighting. It's solid state as it uses solid matter, a semiconductor, to generate light.

The semiconductor is made with both a positively and negatively charged element. The positive layer has little openings for the free electrons from the negative component to go through. When an electrical charge is applied to the semiconductor, a stream of excited electrons passing through the holes emits a light.

The two good benefits of LED light bulbs are their very long life and energy efficiency. They just use roughly one tenth as much electrical energy as normal bulbs and therefore offer big financial savings in power expenses as well as a reduced carbon footprint. This actually makes them both cost effective and environmentally friendly.

Their solid state construction and very low heat emissions give them a much longer lifespan. LED light bulbs drastically outlive even compact florescent bulbs and may easily last for a decade or much longer in regular use. This not only saves on the cost of the bulb, but it also saves time and replacement costs. Much better suited to survive rough handling and outside conditions, a LED light bulb can be relied on to work when required most.

Since they reach their full brightness almost immediately and are mercury free, LEDs clear up two major problems that compact fluorescent bulbs have (mercury content as well as lag time in reaching full brightness).

LED light bulbs are meant to emit an extremely directional light so the light may be aimed precisely where it is needed. Additionally, their light is nearer to the colour of daylight, which research indicate helps people keep alert.

Till recent changes in the technology, the construction of the LED caused much of the light to be trapped inside. This plus the bluish light they typically emitted brought on a dimmer light that made LEDs unpleasant for home use.

LEDs are now much brighter though and may emit exactly the same soft, white light regular bulbs do.

One drawback with LEDs that has not been corrected yet is cost. While their power savings and very long life mean LEDs are cost-effective and save money in the long run, they are not likely to attain mass consumer acceptance until their prices come more in line with other types of bulbs. Although their prices are coming down, LED light bulbs are still comparatively expensive.

As soon as their prices come down more, LEDs are likely to become the standard and dominate lighting until a greater technology appears.
