Model: LBOX01 (Features: A, C & D)
With the help of different light sources, undesired metameric effects become visible. Metameric colours that seem to be the same under one light source, will suddenly show colour differences when viewed under a different light source. To avoid metameric effects it is necessary that the colour to be judged match the spectral reflection qualities of the colour sample as much as possible. |

Only after visual determination of the colour it is recommended to define the colour in a technically measured way. The visual quality control (comparison of determined colour and production sample) following should take place under D65. |

Model: LBOX02 (Features: A, B, C, D & E)
Creates constant proofing conditions for visual quality control. Offers manual and programmable selection of light sources and an automatic mode which is important to maintain regularity when viewing different colours by providing a constant test criteria. Permanent monitoring of the life span for all tubes ensures a consistent test environment by avoiding the use of aged tubes that no longer have the correct light colour. The digital display, along with diodes that change in appearance serve as a reminder to change tubes in a timely manner. |
