Luminos Consulting was established in 2009 and the company specialises in conducting Luminance Contrast Tests. We have conducted these tests both on-site and in laboratories for various installations.

We were originally established out of a Disability Access Consultancy due to an increased demand for luminance contrast and increasing requirements of the complexities of the testing methodologies.

Luminos Consulting has provided services to many clients, from single operators to international companies. Within the disability access consulting industry, Luminos Consulting are considered the industry leader when it comes to conducting luminance contrast tests on behalf of Accredited Access Consultants.

Please do not hesitate to contact us should you require any assistance with luminance contrast testing or just need assistance with colour selections.

Testing procedures

For the purposes of determining the most accurate luminance contrast ratios, Luminos Consulting perform three (3) testing methodologies in both on-site and laboratory tests;

  1. Photometer Testing – This testing methodology is inclusive of ambient lighting conditions. Within non-onsite tests Luminos Consulting test under varying lighting (LUX) levels.
  2. Tristimulus Colorimeter (d/0) Testing – This testing methodology is conducted under D65 lighting delivered via the equipment and remains constant across all tests. Please note that Luminos Consulting use the only compliant equipment (Konica Minolta CR400). This test is specular inclusive. Specular inclusive is the accurate measurement of the light reflectance from the colour and is not influenced by surfacing finishes.
  3. Spectrophotometer (45/0) Testing – This testing methodology is considered the most accurate in terms of luminance contrast testing. Please note that this testing does not meet the stated instrumentation in AS1428.1 – 2009 & AS1428.4.1 – 2009. This test is inclusive of colour and surface finishing.
