A one piece assembly fluorescent light fitting device complete with internal high frequency ballast designed to enable the assembly to be installed into an existing T8 or T12 light fitting, allowing a T5 fluorescent tube to be fitted in the T8 or T12 fitting for operational purposes. A one piece assembly with an internally fitted high frequency ballast when installed in a T8 or T12 light fitting isolates and makes redundant the existing 60hz -100hz ballast required to operate the T8 or T12 and supplies the correct high frequency power to enable operation of the T5 tube. A one piece assembly which enables a T5 tube, which is shorter in length and smaller in diameter than T8 or T12 tubes, to be fixed in an existing T8 or T12 light fitting for operational purposes, thus eliminating the need to remove the existing T8 or T12 light fitting and the need to install a completely new T5 light fitting.
