LED Bulb

 As of July 2007 before and after, fluorescent materials, the highest performance is Idemitsu Kosan (Idemitsu Kosan) of the material. Red light efficiency of 11cd / A, lifetime

LED Bulb

Up to 160,000 hours; green efficiency 30cd / A, life is 60,000 hours; being developed for high efficiency, long life blue material BD-2 (0.13, 0.22), efficiency of 8.7cd / A, lifetime 23,000 hours .

LED Module

Phosphorescent materials, UDC has developed a red material chromaticity coordinates of (0.67, 0.33), efficiency of 15cd / A, 500 cd / m ^ 2 under the working life of over 150,000 hours; green material color coordinates (0.34, 0.61), efficiency of 65cd / A, the initial luminance of 1000 cd / m ^ 2, the life of over 40,000 hours; hardest to get blue

Phosphorescent material efficiency reached 30cd / A, at 200 cd / m ^ 2 of the initial brightness, the life expectancy of 100,000 hours.

  LED Flexi Strip

Overall, OLED red, green, and blue color material life of both the luminous efficiency and meet the basic needs of practical.

From the above data it seems, is now an OLED at 500cd / m ^ 2 under at least 20,000 hours of operating time.
