I always get suspicious when strata managers and committees give two or more unrelated reasons why work isn’t being done. Do they need approval to spend the money or do they want to run a poll on the style of lighting. No point in the latter without having the former.
I would put a crisp new $5 note on this being a dispute between factions on the committee who want different kinds of lights. Maybe some committee members who didn’t want the expensive eco-friendly lights are demanding cheaper, planet destroying ones. Or someone wants a hip industrial look while other want discreet hidden lights.
Either way, submit a motion to your next committee meeting that the committee explains in detail why your foyer looks like a set from a renovation TV show that’s been cancelled mid-season. And add a second motion that the committee approves the funding to finish the job or, if they don’t have the power to do that, they call an EGM to get the approval.
You are right to be angry and suspicious – so demand on-the-record answers and action.
