LED’s have evolved and revolutionised the lighting industry with energy saving lights and have been put to many other uses in various industries. LED technologies have evolved from standard cluster of red, green and blue to Surface Mounted Diodes (SMD). Most modern screens and lighting use the SMD modules.

Conventional LED’s are however better in brightness, colors, life and are used for most of the outdoor LED screens such as outdoor billboards and or mobile LED screen vehicles. SMD’s are used more for indoor screens.
