The Pros And Cons Of LED Light Bulbs2909386

Because the compact florescent light bulb has began to rapidly replace the aging incandescent light bulb lately, a new type of bulb is emerging which will replace them both. The light emitting diode (LED) bulb has benefits that make it a better technology.

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

The semiconductor consists of both a positively and negatively charged part. The positive layer has little openings for the free electrons coming from the negative element to cross through. When an electrical charge is applied to the semiconductor, a circulation of excited electrons passing through the holes emits a light.

The two excellent benefits of LED light bulbs  are their long life and energy efficiency. They just use almost one tenth as much electrical energy as conventional bulbs and thus offer huge savings in power expenses and a reduced carbon footprint. This actually makes them both cost efficient and eco friendly.

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

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

LED light bulbs are meant to emit an extremely directional light so the light could be aimed exactly where it's required. Also, their light is nearer to the colour of daylight, which research indicate helps people keep alert.

Until recent changes in the technology, the structure of the LED induced much of the light to be trapped inside. This plus the bluish light they often emitted brought on a dimmer light that made LEDs unpleasant for home use.

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

One disadvantage with LEDs that has not been solved yet is cost. While their power savings and very long life mean LEDs are cost-effective and save money in the long term, they are not likely to achieve mass consumer acceptance until their prices come more in line with other sorts of bulbs. Though their costs are coming down, LED light bulbs are still relatively pricey.

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