The Pros And Cons Of LED Light Bulbs

As the compact florescent light bulb has started to rapidly replace the aging incandescent light bulb lately, a brand new kind of bulb is emerging that may replace them both. The light emitting diode (LED) bulb has advantages that make it a better technology.

While the incandescent bulb produces light within a vacuum and the compact florescent bulb does so inside a tube, the LED is referred to as solid-state lighting. It is solid state because it makes use of solid matter, a semiconductor, to generate light.

The semiconductor consists of both a positively and negatively charged component. The positive layer has small openings for the free electrons coming from the negative element to pass through. When an electric 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 really long life and energy efficiency. They only use almost one tenth as much electricity as traditional bulbs and thus offer enormous financial savings in power expenses and a decreased carbon footprint. This actually makes them both cost effective and eco friendly.

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

Since they reach their full brightness almost instantly and are actually mercury free, LEDs solve 2 main issues that compact fluorescent bulbs have (mercury content as well as lag time in reaching full brightness).

LED light bulbs are built to emit an extremely directional light so the light can be aimed precisely where it is required. Additionally, their light is nearer to the colour of daylight, which studies indicate helps people stay alert.

Till recent changes in the technology, the construction of the LED induced much of the light to be trapped inside. This in addition to the bluish light they usually emitted brought on a dimmer light that made LEDs unattractive for home usage.

LEDs are now a lot brighter though and could emit the exact same soft, white light regular bulbs do.

One drawback with LEDs that has not been corrected yet is cost. While their energy savings and long life mean LEDs are cost-effective and save money in the long term, they are unlikely to attain mass consumer acceptance until their costs come more consistent with other sorts of bulbs. Although their costs are coming down, LED light bulbs are still comparatively pricey.

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