The Advantages And Disadvantages Of LED Light Bulbs

Since the compact florescent light bulb has began to quickly replace the aging incandescent light bulb lately, another kind of bulb is emerging that will replace them both. The light emitting diode (LED) bulb has benefits that make it a superior 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's solid state because it makes use of solid matter, a semiconductor, to generate light.

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

The two excellent advantages of LED light bulbs are their really long life and energy efficiency. They just use about one tenth as much electrical energy as usual bulbs and thus offer enormous savings in power costs as well as a decreased carbon footprint. This actually makes them both cost effective and eco friendly.

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

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

LED light bulbs are designed to emit a very directional light so the light could be aimed precisely where it's needed. Additionally, their light is closer to the colour of daylight, which studies indicate helps people keep alert.

Till recent changes in the technology, the structure of the LED caused a lot of the light to be trapped inside. This in addition to the bluish light they often emitted brought on a dimmer light that made LEDs unattractive for home use.

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

One downside with LEDs that has not been rectified 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 unlikely to achieve mass consumer acceptance until their prices come more consistent with other types of bulbs. Although their prices are coming down, LED light bulbs are still comparatively pricey.

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