Green Initiative Item 6 – Lighting Retrofit (T5)

T5 lamp is a fluorescent lamp which is more efficient than the conventional T8 lamps. T5 lamps have the highest luminous efficacy when compared with T8 lamps. In addition to high luminous efficacy, T5 lamps are specially designed for operating with electronic ballasts, which can further enhance the efficiency compared with conventional electromagnetic ballast by providing high operating frequency and reducing circuit power losses.

The Environment and Conservation Fund (ECF) relevant Vetting Subcommittees approved a total of 14 services units for TWGHs lighting retrofit pilot project which is to replace the existing fluorescent tubes and ballasts with T5 lamps and electronic ballasts, including the Administration Headquarters, 7 schools and 6 community services centres. Details of the services units and the work progress are listed below:
