Global Trend for LED & Business Prospects
SSL (solid-state lighting) devices are rapidly becoming viable light sources for general illumination applications. In the past, LEDs were used extensively for light indicators and signals. Now, more and more high power LEDs are adapted for use in general illumination for indoor and outdoor applications.

The benefits of using high power LEDs are:

-Environmentally friendly
-Economical
-Long Life (50,000 hrs)
-Robustness - Strength & Reliability (withstand rugged usage)
-Improved safety and security (non flickering)
-Design flexibility and adaptable for signage
-aesthetic design potential
-lack of radiated heat and no UV-light
-dimming
-colour changes
-improved energy efficiency

At time of this writing, the luminous efficacy of LEDs is 80-100 lm/W. More efficient LEDs are now appearing in the market with 160-180 lm/W output @ 350mA current.
