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.

Why to Choose ENERGY SAVING LED Lighting?
 

LED light bulbs to save electricity bills
LED 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 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.

FEATURES OF LED LIGHTS

  • The brightness of LEDs are similar or even better than other lighting technologies.
  • The output light is always constant over long period of time.
  • They have excellent quality of colors.
  • The efficiency is comparable to fluorescent lighting.
  • There is instant bright light without blinking.
  • They don’t have flickers.
  • They do not cause power draw.
