EPC’s model USL-1 is a safelight system suitable for color photographic dodging printers.
• The spectral emission of the solid-state light is in the least sensitive wavelength of most color printing materials.
• The USL’s six-position selector switch, in conjunction with the printer dimmer allows an adjustment range over 1000:1.
The USL-1 consists of two light bars, a control module and connecting cables. The light bar is attached within EPC’s printer with magnetic tape or Velcro. Power requirement is 6 watts at 120V, 50/60 HZ. Lamp emission is yellow.
The USL-2 is suitable for color photographic darkrooms. It consists of a dimmer and selector switch and two to six light bars, attachable with Velcro for wall mounting.
The USL series is designed for use with color print materials, not for panchromatic aerial film.
