Is there anything I need to consider when designing and wiring for this type of system? TN-S without the neutral distributed.

    I would be inclined to "play it safe" and use 0.4 seconds dissconnection times. 


    I would consider two pole switches to be best practice for lamps, In the real world light switches ARE used as the means of isolation when replacing lamps, even if that is not the intention. Do not fancy 133 volts to earth on the shell of an E27 lamp, nor on the exposed metallic parts of a lamp that has been broken.
