LED light-out efficiency has largely risen from 35 lm/W (2006) to 100 lm/W (Q1'2009). From the viewpoint of LED efficiency increasing, LED products that replace traditional lighting have been deeply anticipated, especially in high power consumption products. Due to the lighting market business being very large, there are many new companies joining in recent years. However, LED product quality has become a very big issue, especially in new companies' products since these new companies are not experts in the lighting field.
