JUST Normlicht CHALLENGE 5000 – DLS Challenge 6B

The economic proofing station for 6B format (40×55″) is the entry-level solution for JUST 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 illumination: 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 coordinate (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)
