About LED Lighting - FAQ

What is an LED?

A light emitting diode (LED) is a semiconductor device that emits visible light when electrical current passes through it, it is a special kind of diode.

What are some advantages of LED lighting compared with conventional lighting technologies?

• Lower energy consumption - less greenhouse gas emissions
• Extreme lamp life - lower maintenance
• Less energy & maintenance - less ownership & maintenance costs
• Lower operating temperatures
• Zero IR or UV radiation
• Safe for illuminating precious surfaces & materials
• Resistant to shock & vibration

What colours can LED lightings produce?

Most LEDs are monochromatic (single colour). Light colour is associated with the light wavelength. LEDs made with different semiconductor materials emit lights in different wavelengths. LED light wavelengths range from 400 nanometers (blue) to 800 nanometers (red). The colours of popularly available LEDs in the market are red, orange, amber, yellow, green, blue and white. Most Superlight LED products are available in the full range of LED colours including Warm-White & RGB.
