Advantages include:

- High efficiency - LEDs are now available that reliably offer over 100 lumens from a one-watt device, or much higher outputs at higher drive currents

- Small size - provides design flexibility, arranged in rows, rings, clusters, or individual points

- High durability - no filament or tube to break

- Life span - in properly engineered lamps, LEDs can last 50,000 - 60,000 hours

- Full dimmability – unlike fluorescent lamps, LEDs can be dimmed using pulse-width modulation (P- - WM - turning the light on and off very quickly at varying intervals). This also allows full color mixing in lamps with LEDs of different colors.

- Mercury-free - unlike fluorescent and most HID technologies, LEDs contain no hazardous mercury or halogen gases

still cheaper than here lah....and more choices....
