High-mast lights, once installed with much fanfare, have started to burn a hole in the coffers of the city Corporation, forcing it to review these lighting systems across the city. The issue came up for discussion at the Corporation council meeting held on Thursday. Works standing committee chairperson S. Shafeera Beegum’s proposal to replace metal halide (MH) lights in a high-mast at Karamana Junction with LED lights sparked off the discussion.

It was found that the particular high-mast, installed six years ago, has led to the local body shelling out significant sums as electricity charges. Only four of the 12 lights in it functioned. A study recommended replacing them with LED lamps and installing timer switch to reduce power consumption.
