TST currently spends over 860,000 Baht per year on electricity costs for 700 fluorescent lamps used across its facilities. Replacing the lamps with LED options could significantly reduce costs. Option 1 of replacing lamps with 22W LEDs would save 363,014 Baht per year with a break even point of 2.51 years. Option 2 with 18W LEDs would save 453,768 Baht per year and break even in 1.85 years. Option 3 with 15W LEDs would save the most at 557,833 Baht per year and break even in 2.26 years. The document outlines a plan to obtain quotes from three LED suppliers and submit a capital expenditure proposal, with installation planned to start

1. LED Lamps
Pipeline project by
Kiertichai L. 20 Jul 2015

2. Introduction
Nowadays, Triumph Structures Thailand(TST)
is using fluorescence lamps total 700 EA to
support working area, such as, clean room,
engineering office, store and etc.
However, TST is spending a lot of money, not
only, in fluorescent lamp cost but also in
electricity bill.

3. Current situation
Unit of electricity use per year = Qty of lamp x energy use(36W + loss 2 W) X hour per day x day per year
TST spent total (unit) = 700 x 38 x 24 x 365 = 233,016 KWh/year
TST spent electricity bill = 233,016 x 3.7 = 862,159.20 Baht per year ($25,358 per year)

4. Option 1 LED lamp 22 W
Unit of electricity use per year = Qty of lamp x energy use(22W + loss 0 W) X hour per day x day per year
TST spend total (unit) = 700 x 22 x 24 x 365 = 134,904 KWh/year
TST spend electricity bill = 134,904 x 3.7 = 499,144.80 Baht per year ($14,680.73 per year)
1000
1000
Save cost =862,159.2- 499,144.8 = 363,014.4 Baht (42.11% )
Investment and Break Even Point
• Cost per lamp (Baht) = 1,300 Baht
• Investment = 1,300 x 700 = 910,000 Baht
• Break Even Point = Investment/Saving cost
= 910,000/363,014.40
= 2.51 Years

5. Option 2 LED lamp 18 W
Unit of electricity use per year = Qty of lamp x energy use(18W + loss 0 W) X hour per day x day per year
TST spend total (unit) = 700 x 18 x 24 x 365 = 110,376 KWh/year
TST spend electricity bill = 110,376 x 3.7 = 408,391.20 Baht per year ($12,011.51 per year)
1000
1000
Save cost =862,159.2- 408,391.2 = 453,768 Baht (52.63% )
Investment and Break Even Point
• Cost per lamp (Baht) = 1,200 Baht
• Investment = 1,200 x 700 = 840,000 Baht
• Break Even Point = Investment/Saving cost
= 840,000/453,768.40
= 1.85 Years

6. Option 3 LED lamp 15 W
Unit of electricity use per year = Qty of lamp x energy use(15W + loss 0 W) X hour per day x day per year
TST spend total (unit) = 700 x 15 x 24 x 365 = 91,980 KWh/year
TST spend electricity bill = 91,980 x 3.7 = 340,326 Baht per year ($10,009.59 per year)
1000
1000
Save cost =862,159.2- 304,326 = 557,833.2 Baht (64.70% )
Investment and Break Even Point
• Cost per lamp (Baht) = 1,800 Baht
• Investment = 1,800 x 700 = 1,260,000 Baht
• Break Even Point = Investment/Saving cost
= 1,260,000/557,833.20
= 2.26 Years

8. Concern points
1. Brightness between fluorescent lamp and LED lamp must
be same and pass in customer requirements
2. Long warranty will be our choice
3. Low investment and short in break even point will be our
choice.
4. Brand name or reputable of LED lamp will be our choice.
5. Local supplier and good services after sales will be our
choice.
6. Long life time of LED lamp will be our choice.
7. Short time installation will be our choice.
8. Lamp installation start zone by zone, area by area will be
our choice.
9. Can we sell spare parts of fluorescent lamp?
10. Can we request investment from Thailand Ministry of
Energy for LED lamp implement?

9. Plan and timeline
