This product is not intended to be a light emitter (of its own accord), laser, test instrument, or R/C vehicle; so my standard review format will not be used and the product will not be assigned a rating. This will simply be an informational web page with a smattering of photographs and a video on it.

Fibrance™ Light-Diffusing Fiber is a glass optical fiber optimized for thin, colorful, aesthetic lighting. This technology enables decorative lighting to be designed or embedded into tight or small places where other bulky lighting elements cannot fit.

The flexibility and tight-bend capability of the fiber allows it to curve, wrap, or contour around objects while maintaining bright and uniform light. Also, the fiber is so small and thin it is nearly invisible when the light source is off, thereby enhancing a product’s overall aesthetics and user experience.

Fibrance™ Light-Diffusing Fiber opens new design possibilities for a variety of markets such as automotive, architecture, consumer electronics, or appliances.

From the July 2014 issue of Laser Focus World magazine (page 9) comes this brief article, which quickly led me to contact V.T. at Corning® Incorporated re: getting my hands on these puppies so that I could add them to this website:

Fibrance™ is the term coined by Corning® Incorporated (Corning, NY) for its new optical fibers that distribute a variety of wavelengths of light evenly along their length, much like very tiny and flexible neon tubes. These fibers have nanostructures in the glass core with a standard diameter of ~125 to 200 µm, surrounded by a polymer cladding, that allow the fibers to emit light uniformly across customizable lengths. Standard diffusion lengths are 1, 5, and 10 m, with 50 m lengths possible. For high-power or ultraviolet emission, a glass rather than polymer cladding can be used to efficiently emit these wavelengths.

Light-diffusing Fibrance™ contains a ring of nonperiodically radially and axially distributed scattering nanostructures with diameters of ~50–500 nm. These wavelength-independent scattering centers enable scattering losses as high as 5–7 dBm in fibers with bend radii as small as 5 mm. Large core size and high numerical aperture (0.35 to 0.53) allows low-loss coupling from visible, near-IR, or UV laser diodes. Coupling to LEDs is possible if the fibers are bundled together with a coupling-efficiency tradeoff. Phosphor coatings on the surface of the fiber can be used to change the scattered color or produce white light for display, aesthetic, and industrial illumination applications.

TEST NOTES:
Test units were sent by V.T. at Corning® Incorporated on 08-06-14 and were received on the afternoon of 08-19-14.
I contacted Corning® Incorporated about their Fibrance™ Light-Diffusing Fiber after I read a short article about the product in the July 2014 issue of Laser Focus World magazine; they responded to my message extremely promptly, asked some questions about my intended use of the product, and soon shipped me samples for this website.

Do you manufacture or sell an LED flashlight, task light, utility light, or module of some kind? Want to see it tested by a real person, under real working conditions? Do you then want to see how your light did? If you have a sample available for this type of real-world, real-time testing, please contact me at ledmuseum@gmail.com.

Please visit this web page for contact information.

Unsolicited flashlights, LEDs, and other products appearing in the mail are welcome, and it will automatically be assumed that you sent it in order to have it tested and evaluated for this site.
Be sure to include contact info or your company website's URL so visitors here will know where to purchase your product.
