Retrofitted initiative:
Lighting:
- Replaced the traditional T5 fluorescent tubes in carpark area, in-house corridors and staircase by Excalibur ET5E-ECG LED tubes.
Observed benefits other than energy saving:
- The ET5E T5 LED adopted the "Easy to install" technology developed by Excalibur ESCO. The ET5E match with 95+% of the major ECG ballast in the market, it can help to reduce 50- 60% expenses on the installation and provide extra flexibility for maintenance and future replacement and upgrade.
- No extra expenses required on changing the Emergency kit during the LED retrofit project due to the ballast and wiring are same as before.
- No extra solid waste like the light fixture and ballast will be created due to the fixture, E-kit, and ballast being used after the ET5E LED deployment.
General observations of the retrofitting project:
- Lighting Retrofit was conducted during business hours on weekdays. It slightly affected the usage of the carpark if the retrofitting product required to rewire the wiring from ECG to AC.
- However, the installation of ET5E is easy and does not require any rewiring work. The installation takes much shorter time. (85% off than replacing to a AC tube)
- Prolonged lifetime of the LED tube up to average 50,000 hours
- Adoption of ET5E does not affect the user experience
