Specification answer
CRI narrows the field; the visual task decides the fitting.
The CIE defines the general colour rendering index as the average of the first eight test-colour indices. A published Ra90 value is therefore useful evidence, but it is not a complete description of how materials will appear in a finished room.
Arc documents Ra90, while Flexi and Twist offer Ra90 options. Their output, optic, control and emergency positions differ, so the schedule should name the exact family and configuration rather than relying on a general high-CRI note.
Metric context
Read the CIE definition of the general colour rendering index when setting the project requirement.
Visual review
Use samples or a trial area where finishes, merchandise, food or artwork are business-critical.

Compare the verified family limits before checking the exact model, optic and accessories for the scheme.
| Family | Colour rendering | Output and power | Optic position | Control position |
|---|---|---|---|---|
| Arc | Ra90 | 525–2100 lm at 7–23 W | Narrow, standard and wide | DALI and Casambi available |
| Flexi | Ra90 option | 1100–4975 lm at 8.0–40.5 W | Confirm selected optic | DALI and Casambi available |

Colour-quality brief
Set the requirement around the viewed material.
The better brief names the colour task, the metric, the scene and the evidence needed at approval.
Name the material
Record the finishes, products, food, artwork or skin tones whose appearance matters.
Specify the exact version
Write the required CRI, CCT, output and optic against each luminaire type.
Review the scene
Use samples or a trial area where the final colour impression carries commercial or curatorial risk.
Frequently asked questions
High CRI downlight questions.
Answers are limited to the published options in the compared product schedules.
What does Ra90 mean?
Ra is the general colour rendering index. Ra90 indicates a higher general index than Ra80, but it does not describe every individual test colour or the full spectral character of the source.
Which high-CRI family has the widest output range?
Flexi reaches 4975 lm in the current family data, making it the highest-output route in this comparison.
Do all three families offer DALI?
Arc, Flexi and Twist list DALI options.
Is Ra90 enough to choose a downlight?
No. It is one useful colour-rendering threshold, but beam, colour temperature, output and the materials being lit still matter. Compare tunable-white downlights if colour-temperature adjustment is also required. Colour-critical schemes should also be checked with samples or a mock-up.
Which high-CRI downlights can be aimed?
Arc is a slim directional linear option, Flexi is adjustable across a broad output range, and Twist is a fully adjustable round gimbal.
