LED Challenge D65 / D50

Specifications

The economic proofing station for 3B and 6B formats is the entry-level solution for our LED based stations. With the proven JUST LED technology, proofs can be matched under D50 and D65, while the UV component can be switched on and off. The special prismatic lens provides an even, glare and reflection free illumination.

  • unique JUST LED technology, Fogra certified according to ISO 3664:2009, Pat. No. US 8,592,748 B2
  • switchable: D50 and D65 each with and without UV component for color matching according to the old and new ISO 3664 and ISO 3668 standards
  • UV-ONLY: UV-A for the detection of optical brighteners
  • continuous dimming and USB interface for softproofing
  • no color shift when dimming
  • no warm-up phase after switching on
  • 20 times the operating hours of fluorescent lamps (> 50,000 h) stable light conditions over the entire operating life
  • no tube replacement necessary
  • extremely uniform, glare and reflection-free illumination due to asymmetrical light guidance and prismatic lenses
  • ISO-compliant illuminance of 2000 lux
  • Color rendering (CRI) Ra ≥ 95
  • exact color coordinates (10°):
    D50: x = 0.3478 / y = 0.3595 (≤ 0.002)
    D65: x = 0.3138 / y = 0.3309 (≤ 0.002)
  • low metamerism index in the visible range: ≤ 0.8 (MIvis)
  • low metamerism index in UV range: ≤ 0.6 (MIuv)
  • Sampling area in neutral, matt grey (Munsell N7)

    Illuminant characteristics
