The National Environment Agency (NEA) and the Hong Kah North Grassroots Organisation have commenced the distribution of the $25 voucher to one- and two-room HDB households in the constituency, which can be used to redeem LED lights. This is part of the progressive roll-out of the “Switch and Save – Use LED” (SSUL) programme to one- and two-room households in Singapore, and follows the launch of the programme in the North East District last month.

More than 3,000 households in the Hong Kah North constituency will benefit from the programme. Across Singapore, more than 70,000 households are eligible to receive the voucher.


The aim of SSUL is to help households living in one- and two-room public housing flats to switch to using LED lights, which are more energy efficient.

According to a study by NEA in 2017, one- and two-room HDB households have the lowest adoption rate of LED lights, with only 28% of households using at least one LED light in their home. In comparison, the average LED adoption rate for all the other housing types taken together is 53%.

Eligible households in Hong Kah North are being notified by mail and grassroots volunteers have also been conducting house visits at Bukit Batok West Ave 8 to reach out to the residents. The $25 SSUL vouchers can be used to redeem LED lights at any Home-Fix, Selffix and Sheng Siong stores across Singapore. The vouchers can also be used at Philips Light Lab and SSUL roadshows organised by NEA. The $25 value of the vouchers is enough to cover the cost of four to five LED bulbs.

The programme was launched in the North East District on 18 August. Since then, SSUL volunteers have visited more than 700 households in the North East District and Hong Kah North to inform them on how choosing more energy-efficient appliances, such as LED lights, can help them save money and contribute to climate action. LED lights are 80% more energy-efficient compared to incandescent lights, and 40% more energy-efficient compared to compact fluorescent lights (CFL). LED lights generally can last longer as well, and in the long-run, households can save money on both electricity costs and replacement lights by switching to using LED.

Using more energy-efficient appliances is an important climate action that households can take as electricity is largely produced by the burning of fossil fuels, which depletes our planet’s natural resources and produces carbon emissions. The increasing amount of carbon emissions from human activity contributes to global warming, which is one of the factors behind the long-term trend of rising temperatures that Singapore has been experiencing. Climate change may also result in rising sea levels, which would affect a low-lying country such as Singapore.

If all the eligible one- and two-room public housing flats in Hong Kah North and North East District switch to LED lights, they are expected to collectively save about 438,000 kWh annually. This is equivalent to more than $88,000 in energy savings, or enough electricity to power 220 one- or two-room flats for a year. The energy saved would also result in the reduction of carbon dioxide emissions by more than 180 tonnes per annum.
