What is LED lighting?

At its most basic, LED stands for Light Emitting Diode.

This is light produced using a semiconductor in a process called electroluminescence.

The process is much more efficient than what is used by traditional incandescent lights and has a much longer lifespan. Its small size and relatively cooler operating temperature means that it can be used in shapes and forms that would have been impossible to light with traditional bulbs.

Why use LED Lighting?  

LEDs are a green product that provides many environmental advantages.

For starters, they use much less electricity than many other lighting products because of their long life span, they also reduce solid waste when you replace an incandescent bulb with LED, you will prevent fifty 1,000 hour incandescent bulbs from being thrown away.

How long do LEDs really last? 

LEDs have a long lifespan, with most current options rated with at least 20,000 hours of operation. Some brands are pushing that limit and many offer 30,000 to 50,000 hours as standard. This means that you can select a lifespan that will work for your needs. 

What is a driver for LED lighting? 

A LED driver is an electrical device which regulates the power to a LED or a string (or strings) of LEDs. A LED driver responds to the changing needs of the LED, or LED circuit, by providing a constant quantity of power to the LED as its electrical properties change with temperature.

What is a LED driver used for? 

LED drivers also protect LEDs from voltage or current fluctuations. A change in voltage could cause a change in the current being supplied to the LEDs. LED light output is proportional to its current supply and LEDs are rated to operate within a certain current range (measured in Amps).

What is the difference between a LED driver and a transformer? 

LED drivers (also known as LED power supplies) are similar to ballasts for fluorescent lamps or transformers for low- voltage bulbs: they provide LEDs with the electricity they require to function and perform at their best.

What is the difference between Lumens, Kelvins and Watts?

Lumens is a measurement of total light output or in other words the brightness of the lighting. More lumens means it's a brighter light, fewer lumens means it's a dimmer light.

Kelvin is a measurement used to describe the color temperature of a light source. This is the specification that gives a description of the warmth or coolness of a light source.

Watts are a measurement of power consumption. With traditional incandescent light sources typically the higher the wattage, the brighter the light. With energy efficient bulbs such as LED this is somewhat different because there is no hard and fast rule to correlate Wattage with output. 

For example, a LED bulb with comparable brightness to a 60W incandescent is only 8 to 12 watts. But don't bother doing the math -- there isn't a uniform way to covert incandescent watts to LED watts. Instead, a different form of measurement should be used: lumens.
