Fluorescent UVA tubes are not phased out by the Ecodesign Commission Regulation (EU) 2019/2020, neither in 2021, nor in 2023. If they meet the definition of Article 2(1) for “light sources” they are in scope. The (x,y) chromaticity coordinates need to be checked in particular.
If they are in scope, it is to be checked if exemption from Annex III.3(b) or exemption from Annex III.3(c) may apply.
