STA-FLEX LEF 710M LINEAR EMITTING FIBER

Project:
Type: Solid Optic Fiber Cable
Catalog Number: LEF710M
System Component: Optical Fiber

650103_LEF710M

DESCRIPTION:

Lumenyte LEF710M is the brightest linear optical fiber in the industry today. It provides solutions to numerous lighting applications for both issues of luminance (perceived brightness of product when directly viewed) and luminance (resultant foot-candles or lux on a task). LEF710M's flexibility makes it ideal for applications like backlighting, neon replacement and signage. Suitable for exterior, interior and water feature use, it is manufactured in 6" (152mm) increments and sold by the foot. Like all LEF products, it is "driver dependant".

Recommended Distances for Effective LEF710M Brightness

• The effective light-length-output of LEF710M fiber optic is subjective and based upon several variables such as:

• Intensity of light source	• Background color contrast	• Ambient light level
• Quantity of fibers in illuminator	• Viewing angle	• Length of run
• Attenuation of light	• Color of light

• Shorter runs, up to 35’ (10.7m) from one light source or up to 45’ (13.7m) with a light source at each end, are recommended.

Driver

• The LEF Series is “driver dependent”. Therefore, driver length(s) must be specified at time of placing order. Driver lengths of up to 10’ (3m) have minimum impact on photometric performance on a straight run. The minimum bending radius of the fiber is 12” (304.8mm) or greater. A second driver is required when fiber is lit from both ends.
Environment.

Mounting

Environment

• Optical fiber core must be protected in wet or sunlit areas. Use end seals where applicable.

• Protect core and cladding from dirt and abrasions.

•Install fiber at temperatures of 10° C (50° F) or higher.

•Prior to installation, unbox optical fiber and lay fiber straight for several hours.

•Not for underwater use.
