The irradiance measurements are performed at 1 meter, which is considered the working distance of the light.
The radiance measurements are performed with a field of view of 11 mrad, which is considered representative
of the usual eye's exposure (several short time exposures).
The measurements are performed for an illuminance of 130,000 lux for Lucea 100 and 60,000 lux for Lucea 50.
The measurements and calculation are performed according to EN 62471. Only the worst values of each set-
tings and cupolas are summarized below. Please note that the official Group limits may not be relevant for the
specific use of surgical lights.

For Blue light risk, the EN 62471 classification is Risk Group 1**.
For all other risks, the EN 62471 classification is Exempt Group*.
Case of Eye Surgery: Maximum time allowed for a patient's eye under the cupola (positioned at the center of
the light patch), depending upon Illuminance:
Lucea 50
Lucea 100
*Exempt Group (RG 0): where no optical hazard is considered reasonably foreseeable, even for continuous, unrestricted use.
**Risk Group 1 (RG 1): products are safe for most use applications, except for very prolonged exposures where direct ocular exposures may be expected
