Spectral Ranges

The device is available with the spectra UVA or UVB narrowband 311nm, and can be equipped with 40
lamps of the same type, or with a combination of two different spectra with 20 lamps each.

8.6

Accuracy

The dosimetry of the device will maintain a 5% level of accuracy if the device is calibrated annually, or at
least every one hundred (100) hours as recommended.
The spatial variation of the output across the treatment area complies with EN 60601-2-57: 2011 and
does not deviate by more than ±20% from the average irradiance. A reduced output greater than 20% is
possible for the edges of the treatment area (ends of the UV tubes).

8.7

Maintenance & Repair

MEDlight devices are high-quality medical devices for which an annual maintenance is
strongly recommended. As part of the maintenance safety tests and measurements of the
irradiance are carried out, which are necessary to ensure the safe functioning of the
equipment. All work must be carried out only by an authorized MEDlight technician. Circuit
