LED lighting for SK Randagong, Ranau

Being far away from the development of the urban area should not stop you from being efficient in your energy usage. Especially so if you happen to have been adopted by big corporation such as SESB (Sabah Electricity Sdn Bhd).

Energy efficiency is what we want to drive home to the younger generation and SESB did just that to the school children at SK Randagong in Ranau.

Called Energy Efficient (EE) Light programme, SESB started the initiative off in the rural area by 'acting' rather than 'preaching'. SESB came to the school and changed all its conventional light bulbs with energy saving LEDs in September last year, and helped reduce the school’s electricity bill by about 30% the next month. The less-than-expected saving is probably due to power consumption by other appliances that are not energy efficient.

How much?

The  total cost of changing all 35 lights at the school is RM5,350 which works out to be about RM135 per unit. A check with online retailers shows that LED tubes will set you back at RM130 to RM190 per set. Comparing this to the conventional fluorescent tube which is retailed at about RM14 (36 W), it is still a very expensive affair at the current market price.

But life span of LED lights are also about 10 times longer and are brighter,  plus there is virtually no heat generated compared to incandescent/filament and conventional tubes.

Coverage by local dailies, DE, NST and BP was not conclusive as to whether SESB replaced all lights with LED tubes, compact fluorescent tubes or combination of both but looking at the cost involved, I'm convinced they are LEDs.

Why LED? (The LED Revolution)

LEDs are evolving much faster than any other lighting technology. They offer advances in:-

  • Efficiency. Energy savings from 50% to 70% compared with conventional technologies result in similar cuts to carbon emissions.
  • Controllability. Better control over light colour,  intensity and direction allows lighting system designs that can deliver a wide range of social co-benefits. 
  1. Outdoor LEDs offer improved visibility for pedestrians and traffic, as well as reduced light pollution.
  2. Indoor LED smart control systems have been shown to improve student behavior and study performance.
  • Lifespan. Well-designed LEDs are expected to last for 50,000 to 100,000 hours or more. Lifespans can be extended even further by coupling LEDs with smart controls.

According to LED 2012 Report by The Climate Group (Supported and sponsored by HSBC & Philips), when smart controls allow LEDs to dynamically change lighting levels in response to conditions, total system energy savings can reach up to 80%.*

While fluorescent tubes have doubled in efficiency since 1950, white LED efficiency has increased by a factor of ten since 2000. Today LEDs are among the most efficient lighting sources available, but in the near future they will reach far beyond any competing technology and become the technology of choice for most applications – with energy savings reaching up to 90% compared to today’s conventional technologies.

SESB should not stop there. Move on to other schools, higher learning institutions, and collaborate with other GLCs or even local authorities. Get the involvement of the people. Involvement would instill the sense of belonging.

Thumbs up and many thanks, SESB!

aku berkenan sangat dengan lampu LED ni
mungkin leps ni aku akan gantikan lampu yang rosak dengan LED

Saya pun sdh mula berjinak2 dgn LED lightings ni.

RM130 each? No thanks! I'll stick to my RM13 per set fluorescent lamps

We could get a very good view if you post this picture again with LED lights on during night.
