The Basics of Fiber Optic Lighting

When selecting fiber optics for a lighting project, you must carefully consider the end result you are trying to achieve. Although fiber optic lighting offers unique flexibility compared to conventional lighting, it does have its limitations. Areas of high ambient light should be avoided as they tend to “wash out” the color. However, you will find in many cases, that fiber optics can be installed in areas not accessible to conventional lighting.

Brightness: Brightness perception is dependent upon several factors such as color, background, contrast ratio, viewing angle and ambient light conditions. If brightness is critical, then the illuminator model and strand count in the cable are important. The 150-watt metal halide illuminator is approximately 10 times brighter than the 75-watt model and the 575-watt illuminator is 3.5 times brighter than that. Also,. the greater the number of cable strands, the brighter the end result.

Location: Most illuminators are approved for indoor of outdoor use. Some models, however, are indoor only. Adequate ventilation is important for all models. The fiber optic cable is UV protected so it may be installed almost anywhere. Our fiber has been tested at temperatures from -40 degrees Celsius to 200 degrees Celsius.

Port Capacity: The port holds the fibers in place at the light box. The maximum number of fibers varies according to the light box model. Always take into account the port capacity when choosing an illuminator. Remember, perimeter fiber works best when looped in and out of the light box. Therefore, you must double up the strand count on perimeter cable.

Sidelight Cable: Optical fibers glow like neon along their length. However, unlike neon, the cable is virtually unbreakable and is extremely energy efficient. Safety, maintenance and operation cost should also be taken into consideration when making a comparison between fiber optics and neon

This chart will give a general idea of the benefits of sidelight fiber optic cable compared to neon. It does not take into account the electrical utility cost of neon over fiber. On average, neon will cost 3 times as much as fiber on a monthly basis.

Sidelight Cable Runs: By looping the cable, up to 100 foot runs are the brightest possible.  A longer run of up to to 175 feet is possible depending on the application (straight runs, no bends) and illuminator model. Wherever possible, sidelight cable should always be looped in and out of the light source. Not looping is acceptable up to a maximum approximately 35 feet. On long runs, multiple illuminators in series are the norm. They may or may not be synchronized depending the the color effect desired. When using multiple illuminators, always try to keep each cable run as close to the same length as possible. This will ensure the cables uniform brightness.

End Light Cable Runs: Maximum run is approximately 45 feet. However, it should be noted that the shorter the run and/or the more strands, the brighter the end result. If multiple end light fixtures are used, the cable lengths should be uniform on lengths over 35 feet.

Design and Installation Considerations:

Good ventilation in necessary for all illuminators

Light colored reflective surfaces are preferable for end light or sidelight applications. Dark surfaces absorb light and should only be used to provide contrast.

When estimating fiber length, be as accurate as possible. Always allow a few extra feet for a service loop. Remember, you cannot add to the cable once it is cut.

If bending the sidelight cable is necessary, a minimum bend of 1 1/2” radius is recommended. Anything less may create a bright spot at the bend.
