History

LED lightning technology was introduced before forty years. Nick Holonyak, a consulting scientist was the first person who invented LED light emitting diode in 1962. Years later, general technique changed to advanced LED lighning usage. The diodes cost about 200$ which became a major issue at that time. The another major issue was the color i.e. it could produce only red light. Another limiting factor was color, until the 70’s the only color that could be produced by an LED was red. These were the practical issues which took long years to improve. Only few years back, there was improved LED technology and mass installation of various lightning colors in LEDs.

LED light bulbs helps you to save money on your electricity bills
In a home or residential setting, this difference in lifespan and efficiency between incandescent lighting and LED lighting helps you to significantly reduce your electricity bill. In conclusion, a LED light bulb is therefore almost 50 times more efficient in lifespan, and ca. 70-80% more energy-efficient than a conventional incandescent optionLED lights use less power to convert into light. The home that use LED energy efficient lights are supposed to pay less bills than those home that use other alternatives. LED lights are considered to have 50 times efficient lifespan than other lights. In the same way, they are 50/80% more efficient in incandescent option. Therefore, they help to save electricity bills.

LED light bulbs have a for longer life span
Instead of having to replace conventional light bulbs regularly and thereby generating high maintenance costs especially in a large-scale urban municipality setting, LED light bulbs with their exceptional long life time expectancy lead to significant cost-savings in regards to maintenance and replacement workloads.

LED lights are non-toxic and greener than other alternatives
LEDs, in contrast to CFLs, do not contain the highly toxic mercury, which is harmful not only to the environment but also to your personal health. LED lights are free of toxic materials and are 100% recyclable. Most important for issues regarding global warming and environmental change, LED light bulbs release substantially less CO2, sulfur oxide and nuclear waste. Where 30 incandescent light bulbs release about 2500 kg's of these emissions a year, LEDs only produce about 200 kg's annually.

LED lighting is flexible in color and design
LEDs can be dimmed and both light, color and distribution can be dynamic controlled and adjusted either via timers or also remote and even via the internet or your home WLAN. A well-designed LED illumination system can achieve some amazing lighting effects that influence not only the eye but also for the mood and the mind of human beings.

FEATURES OF LED LIGHTS

Brightness is equal to or greater than existing lighting technologies

Light output remains constant over time

Excellent color quality

...

use
The lightning system maintainance a well as bulbs have high maintenance cost when needed to replace and fix them. Especially in large organizations, maintenance cost are very high. LEDs can be the alternatives because they have long life span. Using LEDs help in cost saving from such maintenance. Hence, maintenance and replacements can be minimized.

LED light bulbs as a green alternative bulb
LED lights are free from harmful toxic chemicals such as mercury which is supposed to be harmful to environment as well as health. These lights are 100% recyclable. LEDs release very little amount of CO2, Sulphur oxides and nuclear wastage. Other bulbs release 2500kgs of such toxic substances whereas LEDs release 200kgs of toxic substances annually. Due to these reasons, LEDs can be considered green alternatives.

LED light bulbs for color and design
LED lights are found in various colors and can be adjusted from dimed to bright colors with the help of dynamic control system. Therefore, LED lights can be well designed to get amazing lightning effects for different events. They can be designed easily through internet or from home system.
