FAQ: 
 
1\ What is a LED? 
LED stands for light emitting diode, is an electronic light source.   
 
2\ Why should I choose LED? 
LEDs present many advantages compared with traditional incandescent and fluorescent lights: 1)Lower enerrgy consumption:LEDs produce more light per watt than incandescent and fluorescent.  2) Longer lifetime: LED's may last up to 50 000 hours in many cases, much longer than the incandescent and fluorescent lights.  3) Faster switching: LEDs light up very quickly. A typical red indicator LED will achieve full brightness in microseconds.  4)Environment friendly:unlike fluorescent lamps,LEDs do not contain mercury.   
 
3\ Can LEDs be dimmed?  
LEDs can very easily be dimmed either by Pulse-width modulation or lowering the forward current.   
 
4\ Are LEDs as bright as fluorescent and incandescent? 
Unlike conventional light sources such as incandescent, halogen or fluorescent, the light from an LED is directional. Because of this nature, LEDs can appear almost twice as bright as typical light sources.   
 
5\ Are LED bulbs/tubes easy to install? 
Yes. Installing or changing an LED light bulb/tube is like changing any other bulb/tube, with LEDs’ long lifetime that you’ll need to change it far less often!
