Continuous UVA surface disinfection for occupied spaces.
Leviton DFX series luminaires using 365DisInFxUVA technology- Unless otherwise marked, Leviton DFX luminaires fall under IEC 62471 risk group 0, Photobiological Safety of Lamps and Lamp Systems, with no restrictions on application. If marked on the device and installation instructions with a minimum mounting height Leviton DFX series luminaires meet risk group 0 levels of IEC62471 when installed at or above the marked minimum mounting height, and following the fixture spacing guidelines in this document. Definition of risk groups: IEC 62471 classifies the photobiological risk of light sources into risk groups 0, 1, 2 and 3 (from 0 = no risk through to 3 = high risk). The photobiological safety is measured at a distance of 200 millimeters from the light source. After proper evaluation, a light source is given a risk group (RG) classification, which indicates whether the source presents a risk and, if so, what labeling requirements should be undertaken to alert the user or other protection measures required. A luminaire employing a light source classified RG0 requires no warning or caution.
The safe use of GUV luminaires is specific to only the fixtures listed above. This guide is not to be used for other GUV fixtures. Model Series Fixture Style/Type Sizes Spacing Restrictions Minimum Mounting Height LRTH-DFX Recessed Troffer 1x4, 2x2, 2x4 None None (exempt)
