(10)An expiry date for the exemption should be set in accordance with Article 5(6) of that Directive. The earliest possible date of 12 months from the Commission decision to revoke the exemption should be set given that there are no practical circumstances that would justify a longer expiry time, in particular considering that many of the lamps in question are also covered by Commission Regulation (EU) 2019/2020 which sets minimum energy efficiency requirements to be respected in order for the products to be placed on the market, which will imply that those lamps will not de facto be placed on the market from 1 September 2021.
