I think one really needs more information about the situation on the ground before making any judgements as to what is or is-not appropriate.
If the lights in the garage block are fed from someone else's supply or from a communal/"landlords" supply then I could see them not taking kindly to use of said supply for things other than lighting. There is also the question of what else is on the circuit in question. A 200W or so load won't overload a lighting circuit on it's own but it's not negligible either.
