Frequently Asked Questions about LED Lights

1. Question: what is an LED?

Answer:   LED (Light Emitting Diode)  is a semiconductor device that emits visible light when electrical current passes through it.

2. Question: What are the advantages of LED lights compared with conventional incandescent lights?

Answer:  There are several obvious advantages with LED lights, over conventional incandescent lights:

• Low power consumption - energy saving.
  
• Long lasting  (more than 50,000 hours of life).
  
• Small size and weight.
  
• Fast switching times.
  
• Simple to use.
  
• NO FIRE HAZARD.

3. Question: What LED products are currently available for general customers?

Answer:  There are various kinds of LED light products. They are ideal for replacing conventional incandescent decoration light products, because when compared with incandescent light products, these LED's products save up to 95% energy, have much longer working hours and safer in terms of Fire Hazard. 
At present, people can buy beautiful LED Down-Light, LED rope lights, LED strings light and individual round LED bulbs with many different colors. More other LED products will be available on the market in the near future.

4. Question: Why are LED's of some colors are more expensive than LED's of other colors?

Answer: The reason is that different semiconductor materials are used for different color LED's, and some semiconductor materials are more expensive than others; another reason is that manufacturing costs are different. White LED's are the most expensive because red, green and blue semiconductor material are combined together to make a white LED.

Kilowatt Hour (kWh) Formula:
The measure of electrical energy from which electricity billing is determined.
For example, a single 50 Watts incandescent bulb operated for 1000 hours would consume 50 kilowatt hours (50 Watts x 1000 hours = 50 kWh). At a billing rate of Au$0.17/kWh (50 kWh x Au$0.17/kWh), this incandescent bulb would cost Au$8.50 to run.
