1, energy saving. 2, long life. 3, the applicability is good, because a single LED is small in size and can be made into any shape. 4, the response time is short, the NS (nanosecond) level of response time, while the ordinary luminaire is the MS (millisecond) level of response time. 5, environmental protection, no harmful metals, waste easily recycled. 6, brilliant color, light color pure, narrow spectral range, and through the red green and blue three primary colors mixed into colorful color or white. Disadvantages: 1, the price is expensive. 2, there is still a big gap between luminous efficiency and theoretical light efficiency. 3, there is still a big gap between the current life and the theoretical life (10W hours). 4, there is still a certain amount of fever. 5, can greatly reduce the light attenuation.
