Green Initiative Item 8 – LED Exit Signs

LED is a semiconductor diode supported by a reflector and encapsulated with an epoxy lens for controlling light distribution. The luminous efficacy of LEDs is ranged from about 12 to 55 lm/W, depending on the lamp colour (white is 30 lm/W and red is 55 lm/W). It is much energy efficient than incandescent bulbs. Most LEDs have an operating life of 50,000 hours under normal conditions while other light sources are generally rated at 1,000 to 10,000 hours. The long operating life results in lower maintenance costs or even no maintenance at all.

The Environment and Conservation Fund (ECF) relevant Vetting Subcommittees approved a total of 14 services units for TWGHs LED Exit signs pilot project, which is to replace the existing conventional Exit signs using fluorescent lamp with LED, including the Administration Headquarters, 5 schools and 8 community services centres. Details of the services units and the work progress are listed below:
