Money saved by changing fluorescent tube to LED bulb

(adsbygoogle = window.adsbygoogle || []).push({});

The lighting system in my rented home is evolved from fluorescent tube to halogen bulb and finally to LED bulb.

A quick ROI analysis,

1. Fluorescent tube (36 watt) to LED bulb (6 watt)

Power saved is 30 Watt. For 24 hours usage, total watt saved is 720 watts or money saved is RM 0.157.

Total money saved in a year is RM 57.3.

ROI is [43.9/57.3]*12 = 9.2 months.

2. Halogen bulb (25 watt) to LED bulb (6 watt)

Power saved is 19 Watt. For 24 hours usage, total watt saved is 456 watts or money saved is RM 0.01.

Total money saved in a year is RM 36.3.

ROI is [43.9/36.3]*12 = 14.5 months.

The money and energy saved in a home may look small, but when you consider 6 to 7 million homes in Malaysia, the money saved per year from LED bulbs can go up to 1 to 2 billions.
