COI CLEANROOM For specific medical and clean-room laboratory applications

WHY COI COMPLIANCE? As cyanosis is a visual cue of an underlying medical condition, a light quality which permits accurate observation of “normal” and “blueish” skin tones is essential to the medical staff. The COI of a light source has been established as the parameter that determines its suitability for visual detection of cyanosis. Light sources with a COI of 3.3 or less, a Correlated Color Temperature (CCT) between 3300K and 5300K and a Color Rendering Index (CRI) equal to or greater than 80 are prescribed in the AS/NZS 1680.2.5:2018 standard in use in Australia and New Zealand (Section 7 Light Source Colour). Light sources with a COI of 3.3 or less, the lower the better, are deemed to provide a light quality that procures visual conditions appropriate to the detection of cyanosis.
