  1. Thailand: Approved Energy Efficiency Requirements for tubular fluorescent lamps
  2. Issue Date:2016-05-08 17:54
  3. Thai Industrial Standard TIS 2337-2557 was adopted on 14 August 2016, specifying energy efficiency requirements for ballasts for tubular fluorescent lamps. This standard prescribes the energy efficiency requirements for ballasts for tubular fluorescent lamps for general lighting purposes in different shapes. It covers the following:

     Minimum energy performance standard of ballasts for tubular fluorescent lamps; 

    Ferromagnetic or electronic ballasts use with fluorescent lamps, a.c. supplies from 10 W to 70 W, voltage of 220/230 V and 240 V at frequency of 50 Hz; 

    Ballast as a separate component or built into the lamp. This standard is scheduled to enter into force on 16 August 2017.
