Frequently Asked Questions about Fibre Optics

Fibre Optic Lighting Systems

What is a light source and what does it do?

The light source is where we turn electricity into light which is then fed into the fibre optic harness.

Light source power is expressed in Watts - the higher the wattage, the more powerful the light source is and the brighter the light output from it is.

The light source also contains any effects wheels, such as a colour or twinkle wheel. Effects wheels can also be purchased separately so you can add a different effect, or enhance the colour changing effect by using one of our unique Varicolour colour wheels.

The light source is the only part of a fibre optic system which contains electricity, and therefore must be housed in a dry environment.

What is a harness and what does it do?

The harness is the 'fibre' part of a fibre optic lighting system. It is made up of many strands of optical fibre which are usually wrapped in a flexible black sheathing for protection.

The harness is used to transport the light from the light source to the end fitting. One end of the harness has a 'common end' which is the connector used to plug it into the light source. The other end is either terminated with a number of metal 'ferrules' which are used to connect the end fitting, or the fibres are left bare for use in star ceilings.

No electricity runs through the harness making it safe to route it through wet or humid areas. It is also safe to touch.

If the harness is to be routed underground where is may come into contact with garden tools or other hazards we recommend that armoured conduit be used to protect it.

What is an end fitting and what does it do?

The end fitting is where the light which was generated in the light source and travelled along the harness is output. End fittings come in many shapes and sizes from tiny star ceiling fittings to large stainless steel pavers. Larger fittings, such as pavers and downlights, have screw threads on the back. These are used to connect them to the harness. Small fittings, such as those for a star ceiling are push fitted on the bare fibre strands. As with our harnesses, there is no electricity or heat in the end fittings, making them safe to touch or walk on. They can also be installed in wet or humid areas without the normal dangers of mixing water and light.
