Maps showing the changes in Tressell ward will be on display while members of the council’s street lighting team will answer questions from the public and listen to people’s observations.
East Sussex County Council is replacing around 5,500 of the borough’s old orange and yellow street lights in the town with energy-saving white LED lights.
The change is part of the council’s drive to reduce its energy budget for the whole of East Sussex by £885,000 over the next three years and reduce carbon dioxide emissions by around 2,800 tonnes.
The council has already saved around £340,000 a year and reduced its CO2 consumption by 2,000 tonnes from switching to LED lights in Eastbourne and introducing part night lighting in other parts of the county.
More details on the changeover in Hastings, which is expected to continue until Spring 2015, are available online at www.eastsussex.gov.uk/streetlights, by visiting Hastings Library, in Claremont, or by calling 01273 337162.
