Background
Existing RTG Work Lightings Used
- Girder 1: 4 X 450W Metal Halide
- Girder 2: 1 X 450W HPS + 3 X 450W Metal Halide
- Gantry Paths: 4 X 300W Metal Halide
- Cabin: 3 X 500W HPS
Total: 15 units of Work Lightings
Problems Faced
High bulbs failure rate (lifespan of 2 to 3 months)
Many different types of wattages and lamps used for RTG Work Lightings
Failed lux requirement for area under driver and girder room
Huge storage spaces required for bulb spares & ballast
Misconception view (Poor color rendering)
PT PRISLIGHT
Objective
Objective
Standardization of work lights (Same wattage, type, color)
Energy savings without compromising safety
Compact light weight (Reduce storage space for spares)
Reduce frequent bulb maintenance
Improve night operation view
HPS (Yellow) CDM (Natural Daylight)

Payback Period
Data collected:
• Based on 16 units of work light used on RTG
• Diesel savings of average 1 liter per night running hour
Diesel Cost: US$1.10 / liter based on 2012
Investment Cost: 16 units x US$800 = US$12,800
Yearly Savings of RTG operation based on 12 hour operation per day:
12 hours x 365 days x US$1.10 = US$4,818
Payback Period:
• US$12,800 / US$4,818 = 2.6 Years (ROI of upfront investment)
• US$6,050 / US$4,818 = 1.3 Years (ROI of difference in investment cost)
12 units of RTGs in Terminal – Diesel savings of US$57,816 yearly
Note: Diesel costs may fluctuate and reduce the payback period.

Quay-Side Crane Lightings
Assumptions:
- 42 units of 1000W HPS Lightings replaced by AP315w CDM Prism.Energy savings of 28.7kw
- Based on 1.22litres savings per engine hour or savings 3.9Kw or about 3.19kwh/litre
- 12 hours utilisation
- Dieisel price in Indonesia US$0.9

Typical QC Simulated PlotsPT PRISLIGHT
Payback Period Calculation
Investment Cost: 42units x US$1350 = US$56,700
Yearly Savings of QC operation based on 12 hour operation
per day:
12 hours x 365 days x US$0.9x (28.7/3.19) = US$35,465
Payback Period:
• US$56,700/ US$35,465 = 1.59 Years (ROI of upfront
investment)
10 units of QCs in BICT – Diesel savings of US$350,465
yearly
