Q. What is ‘LED’ lighting?

A. LED lighting is the term given to lamps or light fittings that produce light using light emitting diodes (LED’s). LED’s are electronic components that convert electrical energy directly to light through the movement of electrons within the material of the diode. This amazing technology has developed at an incredible pace and you now see LED light technology being used for all lighting requirements from home to factory, bicycles to the latest airliners.

Q. In terms of light output vs energy consumption, how does LED compare to other lighting technologies?

A. There is not a simple answer to this question as there is a great deal of variation in output for particular lighting technologies.

For example, a brand new, just out of the box, specialised metal halide lamp can give over 100 lumens per watt (lm/W), a measurement of light produced for a unit of energy consumed. However, a more standard metal halide fitting that has been installed for six months may only be giving 50lm/W.

Another consideration is that LED technology is constantly evolving and improving, meaning that the performance comparison with other lighting technologies is constantly changing in the favour of LED.

As a rule of thumb the following ratios are commonly used within the lighting industry:

Halogen vs LED                     10:1
Sodium vs LED                      3:1
Metal Halide vs LED           3:1

For an accurate comparison

Q. What is the definition of LED?

A. LED is the acronym for ‘light emitting diode’, an electrical component that produces light when electricity is passed through it.

Q. How do LED’s create light?

A. LED’s are light producing semiconductors. By applying voltage (an energy source), electrons within the semiconductor material are excited and start to move causing them release photons, or as we see it, light.

Q. What is the best way to compare the output of LEDs with other light sources?

A. A simple quick answer is that LED produces good quality light and uses comparatively little energy. This is clear to see as LED becomes the lighting technology choice for a huge range of domestic and commercial applications.

To go into more detail we need to understand how light is measured.

Unsurprisingly, there are a number of factors to consider when comparing light sources, the two important ones being the amount of light being produced, measured in lumens, and the quality of the light produced, measured using a standard called the colour rendering index (CRI).

For the lumens figure we tend to look for two pieces of information, the total lumens for the light fitting, but equally importantly, we want to know what the lumens per watt (lm/W) figure is. It’s this second figure that tells you how much light the fitting will produce for a unit of energy (in this case watt) consumed.

Natural white light such as sunlight is made up from a broad range of different colour light waves, combining these to produce white light that depicts all the colours that we see. CRI measures the broad light wave spectrum of light, with 100 being the highest score and anything above 80 deemed to pretty reasonable for colour replication.

A great example of a light technology that had produces lots of light (lumens) but has terrible CRI, is sodium lighting. Everyone will be familiar with the streetlights with the orange glow. Have you ever looked at a red car in this light? It looks black, and this is because the light is putting out a narrow band of light (low CRI) that does not allow us to see colours as we expect to see them in normal daylight.

So to summarise, to compare any artificial light source we need to look at the number of lumens produced and the CRI figure.
