The UL Line Light is the latest design in the Metaphase family of LED lights for line scan.  Its narrow, structured beam delivers high intensity and concentrated light for the narrow field of view of a traditional line scan camera.  The high intensity and uniformity allows the UL Line Light to be used as front light to inspect for material defects, angled to obtain an off-axis effect to highlight surface defects, or it may be placed beneath the object for a backlight effect to inspect for holes, voids, or contaminants.  The UL Line Light is available in a wide variety of LED colors; White, Red, Green, Blue, IR, UVS, UVL, and RGB with independent color control up to 120 inches (304.8 cm) in length for large web applications.


  • Passive cooling (no fans needed) with optional compressed air and liquid cooled configurations for higher intensity / higher ambient temperature environments
  • Compressed air [UC] and liquid cooled [UG] versions available
  • Utilizing a full rod focal lens, the lights provide a tight structured beam of light up to 12 inches (30.48 cm).  The optimal working distance is 5 inches (12.7 cm).  For working distances beyond 12 inches (30.48 cm), please see our Collimated Line Light offerings. 
  • Compliance: ETL Listed, UL Standards, CE, RoHS
  • High uniformity (±5%) makes the UL Line Light ideal for front and back lighting line scan applications
  • 24 VDC versions have built-in current driver(s) that provide consistent illumination output


The following are versions of the UL-Line Light that are built in the same style but were not of the configuration certified to ETL.

*UX-LL: Lights with options such as M12 connectors that were not a part of the sample sent to UL

UG-LL: Liquid cooled versions

UC-LL: Compressed air cooled versions


  • Web inspection (foil, plastic film, PCBs, glass, paper, web converting, etc.)
  • Geometry measurements of long targets
  • Direct position measurement
  • Printed circuit board inspection
  • Tube or bottle inspection
  • Machine Vision & Automation 
  • Robotic Inspection

Driver & Strobe Options

We Offer our lights with many different driver configurations to make the lights compatible with the latest LED controllers and Vision Cameras. This provides greater flexibility, control, and convenience when integrating Metaphase illumination systems.

some drivers may not be compatible with all sizes due to current requirements etc. Please contact a Metaphase Representative for details.

Please call Metaphase at 215-639-8699 or your local representative for any additional information.
