Towards LED lamps for school lightings

Contributed by ANG JOO LIAK

Current situation:
There are many dim yellowish lights along the school corridors as well as indoors (e.g. Conference Rooms and LTs). These are incandescent bulbs or some compact fluorescent lights (CFL).

Improvement:
Research and development has shown that LED lamps last longer, and much more energy efficient than incandescent filament bulbs and CFL. The energy cost savings and better lighting for safety (outdoor) and staff & students' eyesight (indoors) are important reasons to switch all lighting to LEDs as soon as possible. Reference: 4 August 2018 The Straits Times, B9, article "The future's bright". - each LED annual energy cost = $3.11, saves 75% over incandescent lamp (say $10). Suppose 300 lamps changed.
