Unknown fluorescent fitting - internal layout after correction

The strange fluorescent light gets the conversion completed properly. In service it was converted to take two tubes, however in my eyes it was hardly a conversion, more a terrible bodged effort to get more light. Because earth continuity was very poor, the tubes struggled to strike, hence it needing work desperately.

In its received condition, both lamp holders each end were basically touching the diffuser meaning both tubes were too. As a result you got a nasty bright line along both sides and two blotches of shadows from the lamp holders. Furthermore, the lamps had begun to burn the diffuser, and it had took its toll on one end, as it rather irritatingly cracked as I was attempting to remove it. The terrible positioning meant the diffuser couldn't be compressed properly to remove it.

My conversion comprises of sprung steel bent in such a way where the floating (but screwed back) lamp holders were in the perfect position to accept the tubes and hold them tightly. An earth wire was also ran to each end of the fitting to improve earth continuity. The result - far more reliable starting and no more bright lines inside the diffuser, as well as a much tidier and more professional looking interior.
